This power/ current is continuously allowed up to an ambient temperature of +45°C.
Above +45°C, do not use this power/ current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
2) HiccupPLUS ModeAt heavy overloads (when output voltage falls below 6.5V), the power supply delivers continuous output current for 2s. After this, theoutput is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload
exists. If the overload has been cleared, the device will operate normally. See Fig. 6-3
3) Discharge current of output capacitors is not included.

9. REMOTE ON / OFF FUNCTION
This feature allows to switch-off the power supply output with a signal switch or transistor. A link
between pin 15 and 16 turns the power supply off. Pin 15 is referenced to the (-) output voltage.
The open-loop voltage between pin 16 and pin 15 can be up to 18V, the maximum current, when inremote OFF mode, can be up to 2.5mA.
The threshold level to switch-off the output is typically 5V and the turn-on threshold is typically 9V.
When multiple power supplies are connected in parallel, pin 15 and pin 16 are also allowed to beparalleled to control all units with the same switch or transistor.
Please note: The shut-down function has no safety feature included.

11. LIFETIME EXPECTANCYThe Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by
the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours andis 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.

12. MTBF
MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicatesreliability 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.
The MTBF figure is a statistical representation of the likelihood of a device to fail. 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 cannot be
determined if the failed unit has been running for 50 000h or only for 100h.

25. APPLICATION NOTES
25.1. PEAK CURRENT CAPABILITY
The unit can deliver peak currents (up to several milliseconds) which are higher than the specified short term currents.
This helps to start current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state
coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state
current and usually exceeds the nominal output current (including the PowerBoost). The same situation applies whenstarting a capacitive load.
The peak current capability also ensures the safe operation of subsequent circuit breakers of load circuits. The loadbranches are often individually protected with circuit breakers or fuses. In case of a short or an overload in one branch
circuit, the fuse or circuit breaker need a certain amount of over-current to open in a timely manner. This avoids
voltage loss in adjacent circuits.
The extra current (peak current) is supplied by the power converter and the built-in large sized output capacitors of
the power supply. The capacitors get discharged during such an event, which causes a voltage dip on the output.
The following examples show typical voltage dips for resistive loads:
Fig. 25-1

32A peak current for 50ms , typ.
(2x the nominal current)

Fig. 25-2 80A peak current for 5ms , typ.
(5x the nominal current)

Fig. 25-3 48A peak current for 12ms , typ.
(3x the nominal current)

Please note: The DC-OK relay triggers when the voltage
dips more than 10% for longer than 1ms.

Peak current voltage dips

Typically from 12V to 8.6V at 32A for 50ms with resistive load
Typically from 12V to 7.4V at 80A for 2ms with resistive load
Typically from 12V to 7.1V at 80A for 5ms with resistive load

25.2. 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.
The maximum allowed feed-back-voltage is 25Vdc. The maximum allowed feed-back peak current is 64A. Higher
currents can temporarily shut-down the output voltage. The absorbing energy can be calculated according to thebuilt-in large sized output capacitor which is specified in chapter 6.

25.3. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 30A (UL) and 32A (IEC). An external protection is only
required if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In
some countries local regulations might apply.
If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of
the circuit breaker. A minimum value of 6A B- or C-Characteristic breaker should be used.

25.4. OUTPUT CIRCUIT BREAKERS
Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems andmay also be used on 12V branches.
MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to
the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.
To avoid voltage dips and under-voltage situations in adjacent 12V branches which are supplied by the same source, afast (magnetic) tripping of the MCB is desired. A quick shutdown within 10ms is necessary corresponding roughly tothe ride-through time of PLC's. This requires power supplies with high current reserves and large output capacitors.
Furthermore, the impedance of the faulty branch must be sufficiently small in order for the current to actually flow.
The best current reserve in the power supply does not help if Ohm’s law does not permit current flow. The following
table has typical test results showing which B- and C-Characteristic MCBs magnetically trip depending on the wire crosschapter and wire length.

25.5. PARALLEL USE TO INCREASE OUTPUT POWER

Unit AACPower supplies can be paralleled to increase the output power. The output
voltage of all power supplies shall be adjusted to the same value (±100mV)
with the same load conditions on all units, or the units can be left with thefactory settings. There is no feature included which balances the load current
between the power supplies. Usually the power supply with the higher
adjusted output voltage draws current until it goes into current limitation. Thismeans no harm to this power supply as long as the ambient temperature stays
below 40°C.

If more than three units are connected in parallel, a fuse or circuit breaker with a rating of 25A or 32A is required oneach output. Alternatively, a diode or redundancy module can also be utilized.
Energize all units at the same time to avoid the overload HiccupPLUS mode. It also might be necessary to cycle the input
power (turn-off for at least five seconds), if the output was in HiccupPLUS mode due to overload or short circuits and therequired output current is higher than the current of one unit.
Keep an installation clearance of 15mm (left / right) between two power supplies and avoid installing the power
supplies on top of each other. Do not use power supplies in parallel in mounting orientations other than the standard
mounting orientation (terminals on bottom of the unit) or in any other condition where a derating of the output
current is required (e.g. altitude, …). Pay attention that leakage current, EMI, inrush current, harmonics will increase
when using multiple power supplies.

25.6. PARALLEL USE FOR REDUNDANCYPower supplies can be paralleled for redundancy to gain higher system availability. Redundant systems require acertain amount of extra power to support the load in case one power supply unit fails. The simplest way is to put two
decoupled power supplies in parallel. This is called a 1+1 redundancy. In case one power supply unit fails, the otherone is automatically able to support the load current without any interruption. Redundant systems for a higher power
demand are usually built in a N+1 method. E.g. five power supplies, each rated for 16A are paralleled to build a 64A
redundant system. For N+1 redundancy the same rules apply as for increasing the output power, see also chapter 25.5.
Please note: Always use a redundancy module to decouple power supplies from each other. This prevents that thedefective unit becomes a load for the other power supplies and the output voltage cannot be maintained any more.
Recommendations for building redundant power systems:
a)
b)
c)

Use separate input fuses for each power supply.
Monitor the individual power supply units. Therefore, use the DC-OK relay contact of the CP10 power supply.
It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

Unit AACPower supplies of the same type can be connected in series for higher
output voltages. It is possible to connect as many units in series as needed,
providing the sum of the output voltage does not exceed 150Vdc. Voltages
with a potential above 60Vdc are not SELV any more and can be dangerous.
Such voltages must be installed with a protection against touching.

Keep an installation clearance of 15mm (left / right) between two power
supplies and avoid installing the power supplies on top of each other. Do not use power supplies in series in mounting
orientations other than the standard mounting orientation (input terminals on bottom of the unit).

Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

25.8. INDUCTIVE AND CAPACITIVE LOADSThe 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 5F are connected to the
output, the unit might charge the capacitor in the HiccupPLUS mode (see chapter 6).

25.9. CHARGING OF BATTERIESThe power supply can be used to charge lead-acid or maintenance free batteries (SLA or VRLA batteries).
Instructions for charging batteries:a)
