SHORT-FORM DATAGENERAL DESCRIPTION
The FPT300 is an industrial grade power supply for the 3-phase mains
system incorporated in a rugged wall- mount housing with a degreeof protection IP54.

Output voltage
Adjustment range
Output power

It provides two to four stabilized outputs that is galvanicallyseparated from the input. The negative potential of the outputs ispermanently connected to PE within the unit.
The most outstanding features of the FPT series are the compact
size, the wide operational temperature range, the extremely low
input inrush current and the very high efficiencies, which areachieved by various design technologies. Large sized output
capacitors can absorb and store regenerative energy from breaking
motors.
Various connector options support the different needs of individual
applications. Please contact PULS for possible options. Highimmunity to transients and power surges as well as low
electromagnetic emission and an international approval package
makes usage in nearly every application possible.

OutputThe outputs provide a (PELV/ES1) rated voltage, which is galvanically isolated from the input voltage. The negative terminal of the outputs ispermanently connected to PE within the unit. Do not connect any output to PE (Ground)
The device is designed to supply any kind of loads, including capacitive and inductive loads. If capacitors with a capacitance >100mF areconnected to one output, this output might switch off after turning the unit or the output on or connecting the load.
All outputs are individually current limited. In case of an overload, the individual output switches off and needs to be reset manually with thereset button on the front of the device. A cycling of the input power does not reset the output. The failure signals are stored until a reset isintentionally initiated.
For protection reasons a delay of at least 5 seconds is mandatory, before an output can be reset after it has switched off. Otherwise the green
LED will be flickering after pushing the button. The unit will be shipped with all outputs turned on. The ON/OFF function has no safety featureincluded.
The sum of the configured output power of all outputs may exceed the total output power of available power. If this is the case, the output
with the highest number will switch off first followed by the next output to ensure that the lower output number will supply continuous powerand see no voltage dips.
Outputs start sequentially from 1 to 4 with an interval of 150ms.

Lifetime Expectancy
The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime expectancyof the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the capacitor’s
manufacturer specification.
The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131 400h). Any number exceeding this value
is a calculated theoretical lifetime which can be used to compare devices.

MTBF
MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It
is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
A MTBF figure of e.g. 1 000 000h means that statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can
not be determined if the failed unit has been running for 50 000h or only for 100h.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

LED Bar Overview
The user menu consists of the LED bar display and 3 push buttons for monitoring and configuration.
After the start-up of the PSU , the menu is in the output power monitoring mode by default.
Output Power Monitoring
The LED bar shows the actual output power in percentage of 300W. At 120W, the green LEDs up to and including 40% would be illuminated.
The LEDs illuminate orange if the delivered power exceeds 300W.
By default, the PSU displays the total output power after startup.
Status LED
The Status LED is used to signal operating conditions.
STATUS LED lights shows solid Green if theDC voltage is above 22V and all outputs are operating according to their settings.
STATUS LED is off if theDC voltage is below 22V or power supply is not powered.
STATUS LED shows solid Red if the
AC input drops below the specified levels.
STATUS LED flashes Orange slowly if theoutput is OFF during the 18s HiccupPlus mode.
STATUS LED flashes Red slowly if
the unit has turned off due to overtemperature. As soon as the temperature reaches normal operating range the output
turns on again and the STATUS LED changes to solid Green.

All parameters are specified at 24V, 12.5A, 400Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.

In power monitoring mode, press UP or DOWN button to change to channel output current monitoring mode.

•

The 7 current scaling LEDs are green (2A to maximum current – depending on the variant)•

One of the upper 4 orange LEDs is steady on and indicating the actual displayed channel.

•

Press UP or DOWN button to scroll between the available channels. After the highest or lowest channel number is reached, the output
power monitor is entered again.

•

If all 4 orange channel indication LEDs are off, the monitoring menu is back in the total output power monitoring mode.

Button lock feature•

Press UP and DOWN buttons simultaneously for 3s. All LEDs will flash for 5s to indicate that button lock status has changed.

•

The display will return to output power monitoring mode.

To Deactivate the button lock feature, press the UP and DOWN buttons simultaneously for 3s. All LEDs will flash for Ss to indicate that
button lock status has changed.

Reset and ON/OFF Push Buttons•

In a failure mode (output has switched off), the output can be turned on again by pushing and holding the reset button for more than
1 second.

•

In normal mode (output has not switched off), a 1 second push will turn the output ON or OFF. For protection reasons a delay of atleast 5 seconds is mandatory, before an output can be reset after it has switched off.

Channel LED Signaling Overview
Below is an overview of the output LED signaling.
LED is off if the
Output is switched off, by button or PSU is not energized.
Channel LED is solid Green if the
Output is switched on, current is below warning threshold (fix 80% of trip setting for units without external interface).
Channel LED flashes Green at a slow rate, 250ms ON / 250ms OFF
Current/Power Budget trip Reason:•

Sum of output currents was above PSU current rating, low priority Outputs get disconnected first.

Channel LED flashes Green at a fast rate, 125ms ON / 125ms OFF, if the
Button is pressed, but unit does not turn Output ON or OFF.
Reasons:•

Button is locked by “external interface” or “button lock feature”.

•

Interval between Charge Up/ Turn on cycles <5s (MOSFET protection).

•

Temperature of MOSFET is >90°C.

PSU output voltage not available.
Channel LED is solid Orange if the
Output is switched on, but current is above overcurrent warning threshold (fix 80% of trip setting for units without externalinterface)
Channel LED flashes Orange at a slow rate, 500ms ON / 500ms OFF, if the
Output is tripped due to overload, or charging a large capacitance.
•

Output overcurrent according to trip setting and curves. After pushing of a button, channel tries to turn on

Channel LED flashes Orange at a medium rate, 250ms ON / 250ms OFF, if the
Installation is Fault, Output Turned OFF. After pushing a button, channel goes to steady OFF.
Condition:•

PSU with NEC outputs: Difference between positive and negative current of the output has been >1A for 6-6.5s•

PSU without NEC outputs: Connector negative wire overcurrent according to negative trip curve, or Output wascontributing to negative overcurrent of another output.

Channel LED flashes Orange at a fast rate, 125ms ON / 125ms OFF, if the
Output is tripped due to short-circuit. The channel's output current exceeded a value of approx. 48A. The reason may be oneof the following:•

electrical short•loads beyond specification•

plugging-in a large capacitance during operation

Channel LED flashes Orange/Green at a slow rate, 250ms orange / 250ms green, if the
MOSFET overtemperature limit is reached (125°C). After pushing a button, channel is turned OFF. After cooling down to 90°C,
the output turns on automatically.

All parameters are specified at 24V, 12.5A, 400Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.

Application Notes
23.1. Repetitive Pulse Loading
Typically, a load current is not constant and varies over time. This power supply is designed to support loads with a higher short-term power
demand (BonusPower®). The short-term duration is hardware controlled by an output power manager and is available on a repeated basis. If
the average load is higher than the sum of all output power, the output voltage will dip.
To avoid this, the following rules must be followed:a)

The power demand of the pulse must be below 200% of the nominal output power.

b)

The duration of the pulse power must be shorter than the allowed BonusPower® time. (see output section 6)c)

The average power should be lower than the nominal output power.

The R.M.S. output current must be below the specified continuous output current. If the R.M.S. current is higher, the unit may respond with athermal shut-down after a period of time.

23.2. External Input Protection
The device is designed, tested and approved for branch circuits up to 20A (UL) and 32A (IEC) without additional protection device. If an externalfuse is utilized, do not use circuit breakers smaller than 6A B- or C-Characteristic to avoid a nuisance trip.

23.3. Two Phases Operation
No external protection devices are required to protect against a phase-loss.
Continuous two phase operation is not recommended for this power class since the supplying
3-phase network could become unbalanced. However, if one phase fails, the unit may continue
to operate if the load is below the power limit shown in Fig. 24-1.
Exceeding of these limits for an extended period may result in a thermal shut-down of the unit.
During power-on, some start-up attempts can occur until a permanent output power isavailable. EMC performance, hold-up time, losses, and output ripple differ from a three phase
operation. Such use is not included in the approval according to UL61010 and IEC62368.

23.4. Inductive and Capacitive Loads
The unit is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors, such as EDLCs (electric
double layer capacitors or “UltraCaps”) with a capacitance larger than 20mF are connected to the output, the unit might charge the capacitor
or the output might trip, chapter 6.

All parameters are specified at 24V, 12.5A, 400Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.

23.5. Back Feeding Loads
Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called return voltage immunity
or resistance against Back- E.M.F. (Electro Magnetic Force).
This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter
whether the power supply is on or off.

23.6. Mounting Orientations
The device can be mounted in various mounting orientations. The listed lifetime and MTBF values from this datasheet apply only for the
standard mounting orientation. The following curves give an indication for allowed output power in different mounting orientations foraltitudes up to 2000m (6560ft).
