OutputThe output provides a SELV/PELV/ES1 rated voltage, which is galvanically isolated from the input voltage. The output ofthe devices includes a decoupling MOSFET for building 1+1 or N+1 redundant power supply systems.
The device 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 1.5F are connected to the
output, the unit might charge the capacitor in the HiccupPLUS mode.
The device is featured with a “soft output regulation characteristic” in order to achieve current share between multiple
devices when they are connected in parallel. The “soft output regulation characteristic” regulates the output voltage insuch a manner that the voltage at no load is approx. 4% higher than at nominal load.

PowerBoost
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)

The fuse breaking current is an enhanced transient current which helps to start heavy loads or to trip fuses on faulty output branches. The output
voltage stays above 20V.

3)

At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the output isswitched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If theoverload has been cleared, the device will operate normally. See Fig. 6-3.

10. Lifetime Expectancy
The 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 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.

11. 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 meansthat 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.

20. Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground.
Type and routine tests are conducted by the manufacturer. Field tests may be conducted in the field using the appropriate
test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well
as all output poles before conducting the test. When testing, set the cut-off current settings to the value in the table below.
It is recommend that either the (+) pole, the (–) pole shall be connected to the protective earth system. This helps to avoid
situations in which a load starts unexpectedly or can not be switched off when unnoticed earth faults occur.

25. Application Notes
25.1. PEAK CURRENT CAPABILITY
The device 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 coiland a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state current andusually exceeds the nominal output current. The same situation applies when starting a capacitive load.
The peak current capability also ensures the safe operation of subsequent circuit breakers of load circuits. The load branches
are often individually protected with circuit breakers or fuses. In case of a short or an overload in one branch circuit, the fuseor circuit breaker need a certain amount of over-current to open in a timely manner. This avoids voltage loss in adjacentcircuits.
The extra current (peak current) is supplied by the power converter and the built-in large sized output capacitors of thepower 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: 20A peak current for
50ms , typ. (2x the nominal current)

Fig. 25-2: 50A peak current for
5ms , typ. (5x the nominal current)

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

25.2. ADJUSTING THE OUTPUT VOLTAGE
A voltage adjustment potentiometer can be found behind the flap on the front of the unit (see chapter ). However, it is
not recommended to change the output voltage since load sharing between power supplies connected in parallel can only
be achieved by a precise setting of the output voltages. The factory settings allow precise load sharing and only qualified
personnel should change the adjustment potentiometer.

25.3. OUTPUT CIRCUIT BREAKERS
Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and may
also be used on 24V branches.
MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to thewire 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 24V branches which are supplied by the same source, a fast(magnetic) tripping of the MCB is desired. A quick shutdown within 10ms is necessary corresponding roughly to the ridethrough 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 cross section and wire length.

25.4. PARALLEL USE TO INCREASE OUTPUT POWER
Power supplies can be paralleled to increase the output power. For redundancy
applications one extra power supply is always needed for sufficient output current
in case one unit fails.
The unit is permanently set to “parallel use” mode in order to achieve load sharing
between devices connected in parallel. The “Parallel use” mode regulates theoutput voltage in such a manner that the voltage at no load is approx. 4% higher
than at nominal load. See also chapter 6.
Energize all units at the same time. It also might be necessary to cycle the input
power (turn-off for at least five seconds), if the output was in overload or shortcircuits and the required output current is higher than the current of one unit.
Keep an installation clearance of 15mm (left / right) between two devices andavoid installing devices on top of each other. Do not use devices in parallel inmounting orientations other than the standard mounting orientation or in any
other condition where a reduction of the output current is required (e.g.
altitude).
Pay attention that leakage current, EMI, inrush current will increase when using
multiple devices.

25.5. PARALLEL USE FOR REDUNDANCYPower supplies can be paralleled for redundancy to gain higher system availability. The unit is already equipped with a
MOSFET as decoupling device on the output to avoid, that a faulty unit becomes a load for the other devices and the output
voltage cannot be maintained anymore.
Recommendations for building redundant power systems:a) Use separate input fuses for each power supply.
b) Monitor the individual power supply units by utilizing the built-in DC-OK relay contacts on each power supply.

Redundancy for 10A output current

Fig. 25-9: Wiring diagram, N+1
Redundancy for 20A output current

Observe the temperature derating requirements of Fig. 25-6 and Fig. 25-7 for N+1 redundancy applications.
Note: Use separate mains systems for each power supply whenever it is possible.

All parameters are specified at 24V, 10A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.

25.6. SERIES OPERATIONPower 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 thesum 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.
Earthing of the output is required when the sum of the output voltage is above
60Vdc.
Avoid return voltage (e.g. from a decelerating motor or battery) which is applied
to the output terminals.
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 (terminals on the bottom of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase
when using multiple power supplies.

25.7. CHARGING OF BATTERIESThis redundancy power supply is ideal for charging batteries due to the decoupling circuit built in to the output stage
which does not require a fuse or diode between the power supply and the battery.
It can be used to charge sealed lead acid (SLA) or valve regulated lead acid (VRLA) lead batteries when following these
instructions:
Instructions for charging batteries:a) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage.
b) Ensure that the output current of the power supply is below the allowed charging current of the battery.
c) Use only matched batteries when putting 12V types in series.
d) The return current to the power supply (battery discharge current) is typ. 3mA when the power supply is switched off(except in case a blocking diode is utilized).

25.8. TWO PHASE OPERATION
The power supply can also be operated on two phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying voltage isbelow 240V+10%.
The maximum allowed voltage between a Phase and the PE must be below
300Vac.

All parameters are specified at 24V, 10A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.

25.9. USE IN A TIGHTLY SEALED ENCLOSURE
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher thanoutside. In such situations, the inside temperature defines the ambient temperature for the power supply.
The power supply is placed in the middle of the box, no other heat producing items are inside the box. The temperature
sensor inside the box is placed in the middle of the right side of the power supply with a distance of 1cm. The following
measurement results can be used as a reference to estimate the temperature rise inside the enclosure.

25.10. MOUNTING ORIENTATIONSMounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous
output power or a limitation in the maximum allowed ambient temperature.
The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves
for continuous operation can be found below:
Curve A1 Recommended output current.
Curve A2 Max. allowed output current (results in approximately half the lifetime expectancy of A1).
