DESCRIPTION:
The Professional Sound Corporation PowerMax Ultra Power Distribution System
has been designed and built specifically to provide clean, quiet power for yourcomplete digital audio recording package. This new design easily handles theheavy power requirements of today’s digital recorders and mixers. Whenconnected to one or two sealed lead acid batteries it can output 12Vdc at up to
30 amps continuous, as well as 15 to 18Vdc (internally adjustable) to power youraudio mixer and wireless receivers. In addition, the PSC PowerMax Ultra
outputs 5 to 9Vdc (internally adjustable) for use in powering consumer digitalrecorders, small video monitors and other equipment. The PSC PowerMax Ultracontains two high capacity, on board battery chargers that are designed tooperate from either 100Vac to 240Vac or from 127Vdc to 370Vdc for worldwide
operation without adjustment. Each of the PSC PowerMax Ultra’s 12 output
connectors are equipped with dedicated EMI/RFI output filters to ensure clean,noise-free power for your equipment. In addition, each of the 12 output
connectors are individually Polyfuse protected and is monitored for proper
voltage output and over current faults. The status of all of these monitors can beviewed form the front panel BI-color LEDs. A green LED indicates proper
operation, a red LED, indicates a tripped Polyfuse (overload condition).

CHARGING:
The PSC PowerMax Ultra contains two built in chargers designed to charge up to
two external Sealed Lead Acid (SLA) batteries. That means you can connect
either one or two separate SLA batteries to the PowerMax Ultra. These batteries
can be 12V. 33AH Pelican battery boxes or large Deep Cycle batteries such as
Optima Yellow Top batteries. The PSC PowerMax Ultra will operate from a wide
range of AC or DC power so you can plug it in anywhere world without having toworry about making adjustments. The charger circuits used in the PowerMax
Ultra have been specifically designed for charging the batteries while thebatteries are in use powering low noise audio equipment. Unlike most battery
chargers, ours have a very low noise floor. Using a typical 33amp/hour SLA
battery you expect a recharge time of about 2.5 hours. Because of the two
independent onboard chargers, when you are using two 33amp/hour SLA
batteries, you can expect the same recharge time of about 2.5 hours. The
charging function is automatic and thus, it does not require your assistance inany way. Simply plug the PSC PowerMax Ultra into an AC outlet, turn on the AC
rocket switch located on the left side of the front panel and the charging begins.
Beware that the PowerMax Ultra may get warm during use. Be careful whentouching the surface of the PowerMax Ultra and be sure to allow ventilation air
gaps around the top panel mounted ventilation fans and also around the sides of
the Powermax Ultra for proper heat dissipation.

The PSC PowerMax Ultra is designed primarily for use with Sealed Lead Acid
batteries. These batteries do not have the memory effects associated with
NiCad batteries and unlike NiCads, SLA batteries life expectancy is based on
how deeply it is discharged, how long it is left in that condition and the number ofdischarge cycles. Thus if you want to get the greatest life from your SLA
batteries, you should keep them charged at all times.
This is easily
accomplished with the PSC PowerMax Ultra as it can be used while charging.
The PSC PowerMax Ultra has a built in “fuel” gauge style battery meter thatallows you to visually see the remaining battery capacity at a quick glance. The
PowerMax Ultra is also designed to protect your batteries from over discharge.
When your battery voltage drops to a pre-determined level (approximately
10.8Vdc) the PowerMax Ultra will automatically shut itself off and disconnect theload from the battery. Thus you cannot over discharge your batteries frommisuse or by accidentally leaving your equipment on over a weekend, etc. The
battery meter is also color coded from green to red as it falls from “FULL”
towards “EMPTY”. When the last red LED turns off, so does the PowerMax
Ultra.

Because the PSC PowerMax Ultra is equipped with such high capacity chargers,
care must be exercised in the type and condition of batteries to be charged. The
PowerMax Ultra is primarily designed to charge Sealed Lead Acid (SLA)
batteries. Additionally, it is recommended that you inspect your batteries
weekly for any signs of damage such as case cracks, leaks or bulging
cases. Do not connect the PSC PowerMax Ultra to batteries that aredamaged, or beyond their recommended life span. Failure to heed thiswarning could result in product damage and/or personal injury. Bulging battery
cases are a sure sign of a damaged battery and/or shorted battery cell. Charging
a battery in this condition can result in excessive heat build up and battery
venting (hydrogen gas discharge and/or explosion). While charging, the sealed
lead acid batteries should only get slightly warm to the touch. If they get very
warm or hot, something is wrong and charging should be discontinued
immediately and the batteries should be inspected.

VARIOUS CHARGER AND BATTERY CONFIGURATIONS:
Single Charger, Single 33AH Battery (1X Pelican Battery)If you are primarily operating off AC and you only want to use a battery for shortterm back up power, then you may wish to use the PowerMax Ultra with only one
33AH pelican battery. When used with only one 12V, 33AH battery, your battery
only run time may be anywhere from 2 to 5 hours depending upon yourequipment’s power requirements. We highly recommend that you use Pelicancase batteries that are equipped with Neutrik Speakon connectors rather than 4
pin XLR connectors. Standard 4 pin XLR connectors are only rated for use at up
to 9 amps of current. As the PowerMax Ultra can charge at up to 15 amps per
battery connection, the use of Speakon connectors is highly recommended.

Dual Charger, Dual 33AH Batteries (2x Pelican Batteries)

One common approach is to use the PowerMax Ultra with two Pelican Batteries.
In this case, you will have 66Amp Hours of power available and your run time onbatteries only will be slightly better than double that of using only one battery.
We highly recommend that you use Pelican case batteries that are equipped with
Neutrik Speakon connectors rather than 4 pin XLR connectors. Standard 4 pin
XLR connectors are only rated for use at up to 9 amps of current. As thePowermax Ultra can charge at up to 15 amps per battery connection, the use of
Speakon connectors is highly recommended.

Dual Charger, Single, Large Capacity Battery (1X Optima Yellow Top
Battery)

Note: Both Charger Leads Connected to One Battery
In some cases, you may wish to use one very large capacity battery with our new
PowerMax Ultra. In this case you can configure both chargers to operate intandem to charge the one battery. This will cut the charging time in half and also
gives you the added benefit of having redundant chargers for reliability. This“Dual Charger” mode should only be used with very high capacity batteries
such as those with amp hour ratings of 55AH or higher. Generally speaking,we are describing full “car size” batteries and upward. Typically this includes
deep cycle batteries such as Optima Yellow Top batteries. DO NOT use this“dual charger” mode on typical 33 amp hour batteries found in Pelicancases as it may result in battery damage and or personal injury. These
smaller capacity batteries will overheat when charged at such a highcharge current and possibly explode.

Dual Charger, Dual, Large Capacity Batteries (2x Optima Yellow Top
Batteries)

This approach will provide the longest run time on batteries only and isrecommended for equipment packages with very high current requirements
and/or for applications that require very long run times on batteries only (No AC
available). In this case, you will have up anywhere from 110 Amp Hours to 150
Amp Hours of power available to operate your equipment while on battery power
only.
BATTERY STORAGE:
Always make sure to charge your batteries before putting them into storage.
Your batteries should not be allowed to go below 10.6Vdc for any extended
period of time. It will permanently damage them. Because all rechargeable
batteries slowly self discharge while in storage, it is recommended that you
charge them every two to three months when you are not using them forextended periods of time. This will ensure that the batteries never self discharge
to a damaging level.

POWERMAX ULTRA USE:
The PSC PowerMax Ultra is designed for use in powering your entire digitalaudio recording package. The PowerMax Ultra’s twelve (12), 4-pin female XLR
output connectors provide all of the various output voltages at all times when thePowerMax Ultra is switched on. Thus all power cables wired for use between thePowerMax Ultra and your equipment must be wired correctly and professionally.
Anytime the PowerMax Ultra is plugged in and the AC power switch in “ON” itsbattery charger is turned on. Thus your batteries may be charged without thePowerMax Ultra’s front panel electronics being turned on. By pressing the round,
RED, “ON” button, the PowerMax Ultra will turn on and begin to supply all of thevarious output voltages to your equipment. If the PowerMax Ultra is connected
to a battery, but not plugged into AC, all of the power will come from the battery.
If the battery is discharged below a safe point, the PowerMax Ultra will not stayon when the “ON” button is pressed. If the battery level is good, the PowerMax
Ultra will latch on. When the batteries are discharged to the point where thebattery meter is readying empty, the PowerMax Ultra will automatically shut itself
off. You can also shut off the PowerMax Ultra at any time by simply
pressing the GREEN, “OFF” button for approximately 7 seconds. This“delayed” off function was designed into the PowerMax Ultra to prevent
accidental shut off of your entire sound package should the “off” button be
accidentally hit. You can also operate the PowerMax Ultra without batteriesconnected by simply plugging the PowerMax Ultra into AC and pressing the “ON”
button. The PowerMax Ultra will output all of the various voltages and supply up
to approximately 450 watts of total output power when connected to AC only.

OPERATING VOLTAGE: (100Vac to 240Vac or 127 to 370Vdc)
The PSC PowerMax Ultra has a “universal” input voltage and can even be
operated from high voltage DC current. This design was chosen to facilitate thePowerMax Ultra operating worldwide with having to be adjusted. Simply plug it
into a properly wired outlet and you are ready to go.

AC LINE SAFETY:Electrical safety codes require that electrical equipment be properly grounded for
operator safety. Many electrical outlets have been miss-wired with hot andneutrals reversed as well as having missing grounds. This is especially true on
film sets were all power lines are portable and neutrals get kicked out time andtime again. For your own safety and for the good of your equipment, you should
test any AC line before connecting to it. This can be done by using a small, lowcost line checker available at most hardware stores. These checkers look like anAC plug with three or four lights on them that indicate when the AC outlet is wired
correctly.

OUTPUT OVERLOAD PROTECTION:
The PSC PowerMax Ultra is equipped with Raychem Polyfuses that
automatically reset to protect the outputs of the PowerMax Ultra and also toprovide a degree of protection to your equipment. These solid state devices act
like ordinary fuses or circuit breakers. They interrupt the flow of dangerously
high electrical current in the case of a fault condition in the equipment being
powered. The PSC PowerMax Ultra contains Polyfuses on its battery inputs, its
voltage regulators and all 36 “hot” output voltage pins. The 36 separate
Polyfuses that protect the 12 output connectors are monitored separately.
The front panel of the PSC Powermax Ultra has 36 BI-color LEDs that provide aconvenient “quick glance” for user monitoring. Under normal operation, all 36 ofthese LEDs should be lit green. This indicates that there are no faults on any of
the outputs. If any one of the LEDs has switched from Green to Red then thatparticular polyfuse has been tripped. Because there are individual LEDsmonitoring the individual outputs, you can easily find out which output has the
problem. For example, the LED for output number 2, has turned from Green to
Red, you now know that whatever device you have plugged into output number 2
has a problem. Also, because each of the individual outputs is individually
polyfuse protected, if any one piece of your equipment has a fault, the rest of
your sound package will continue to operate. These Polyfuses will only reset
after the fault has been removed and the Polyswitch allowed time to cool down
(approximately 30 seconds). Please note that these output protection
devices should not trip during normal use of the PowerMax Ultra! If you
experience tripping of these devices on any continuing basis, something iswrong and a qualified technician should check your equipment and cables
immediately. Additionally, these polyfuses are rated at 4 Amps. This may
be higher than is safe for various types of equipment. Always make sure
your individual equipment is properly fused for its own protection.

Example of Proper Operation

Example of Tripped Polyfuse(Connector #1, Pin 3 Shorted)Additionally, the PowerMax Ultra has internal fuses on the AC supplies that
protect these main power supplies. These 5mm x 20mm white ceramic fuses are
rated at 6.3 amps and are of the “slow blow” type. These fuses should not failunder normal operating conditions. If either of these fuses fail, please take yourPSC PowerMax Ultra to a qualified technician for repair. Failure of these fusesor the power supply itself is indicated when the one or both of the front panel AC
indicators is not lighted when the unit is connected to AC and the main powerswitch is turned on. These front panel indicators are labeled “AC1” and “AC2”Safety note: There are no user serviceable parts within the PSC PowerMax
Ultra. Within the PSC PoweMax Ultra, there may be hazardous voltages
present. Do not disassemble the PSC PowerMax Ultra. Refer all servicing
to a qualified technician.

PROPER POWERMAX ULTRA COOLING:
Your new PSC PowerMax Ultra is a high power device. It has a rated output of
450 watts. Although it has been designed using high efficiency switch-mode
power supplies, the unit still does generate a considerable amount of heat whenrunning at its full rated capacity. This heat must be dissipated for proper
operation of the PowerMax Ultra. Because of this, the PowerMax Ultra isequipped with two, low noise Panasonic fans. These fans where chosenbecause of their efficient air moving abilities, quiet operation and super long life.
In addition, these fans are operated at two different speeds. The low speed isused most of the time. Each of the two main switch-mode power supplies areequipped with thermostatic switches that are used to control the fan’s operation.
When either of the two power supplies reaches 120 Degrees F (49 C) the fans
are automatically switched to operate at their higher speed for additional cooling.

SILENT OPERATION MODE:
There is a back panel mounted, “Fan Remote” connector that can be used tomomentarily override and shut off the cooling fans. This logic level connector
can be used to shut down the cooling fans during filming for completely silent
operation. It can also be connected to many remote roll devices so you can
automatically shut down the fans during every take. Whenever the “Fan Remote”
shutdown is activated, a front panel mounted RED LED that is labeled “FAN
OFF!”, will light, indicating that the cooling fans have been overridden (shut off).
The rear panel mounted “Fan Remote” connector is a 3 pin mini XLR connector.
You can interface to this by using a Switchcraft TA3F connector wired as follows:
Pin 1 = (-) Negative
Pin 2 = (+) Positive
Pin 3 = 12Vdc

Applying 5Vdc to 12Vdc across pins 1 & 2 with the polarity indicated above willcause the Fans to be shutdown for Silent Mode Operation.
Please note that the Fans should only be overridden for short periods of timesuch as when filming a scene lasting from one to several minutes.
The PowerMax Ultra cannot be operated for long periods of time without
the fans on. It will overheat and either shut down or be permanently
damaged. Damage caused by heating due to customer miss-use of the fanoverrides is not covered under the PowerMax Ultra Warranty.
The PoweMax Ultra is also equipped with a front panel mounted AC powerswitch. By turning this switch off, you are shutting down the chargers along withthe fans. If you have long scenes to record and you have batteries connected toyour PowerMax Ultra, then you can use the AC Power Switch as another way of
shutting down the fans for silent operation. Please note that no battery charging
is available when the AC switch is turned off. Because the PowerMax Ultra hassuch high capacity chargers, it can quickly recharge most batteries during breaks
in filming, lunch breaks, wardrobe changes, etc.

EQUIPMENT POWER CABLES:
PSC recommends that you use only two conductor, unshielded 16AWG
power cable for power distribution. Shielded cable is not recommended as
the shield may cause short circuits between adjacent pins on the connectors.
NOTE: Use only the pins required for the correct voltage to operate yourspecific piece of equipment! For example, if your Miranda Mixer requires
12Vdc to operate, then you should only connect pins 1 (ground) and pin 4(12Vdc). In this case you should not use pins 2 (6Vdc) or pin 3 (15Vdc) as thesevoltages are not required and could potentially damage your equipment. Manypieces of equipment use pins 2 and 3 for other functions such as battery
charging. There are no industry standards for the use of pins 2 and 3. Their use
may not be compatible with the PowerMax Ultra. Remember, use only 2conductor cable and wire only 2 pins on your connectors! Please see
examples below:

TYPICAL 12Vdc POWER CABLES:For use with PSC Miranda Mixer, PSC M6 RetroMix, PSC RF MultiMax, PSC RF
Multi Dual 1x8, Cooper CS208, Audio Developments Mixers, and most otheraudio mixers and recording devices that operate form 12Vdc and use a 4 pin

BATTERY POWER CABLES:The cables used to connect the batteries to your PSC PowerMax Ultra are of
special importance as they carry the entire electrical load of your sound recording
package from the battery. In addition, they must carry the entire charge current
to the battery. The battery cables must be made from heavy gauge cable(12AWG) and kept as short as possible to eliminate voltage drops acrossthe cable. Because you are working with 12 volt batteries, the loss of even 1

volt across a cable run is unacceptable. We have equipped the PSC PowerMax
Ultra with Neutrik Speakon connectors for use with your batteries. These
connectors are rated for use up to 30 amps. Each PowerMax Ultra is suppliedwith a pair of cables terminated in ring lugs for use with your SLA batteries. We
recommend that you have all your cables professionally built or buy speciallybuilt cables made by PSC from any authorized PSC dealer.

WARNING: It is highly recommended that you have your cables built by
qualified personnel and tested prior to use with your PowerMax Ultra. All
power cables should be clearly labeled on both ends as to what they are to
be connected to. For example, label one end “PowerMax Ultra” and theother end “Miranda Mixer”. This will help prevent inadvertently connecting
the cables to the wrong piece of equipment. We cannot stress enough theimportance of good quality power cables and careful connections. Poorly
constructed and/or labeled cables can result in equipment damage!
