6. OUTPUT
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.
The output is electronically protected against no-load, overload and short circuit. In case of a protection event, audible
noise may occur.
The output is designed to supply any kind of loads, including inductive and capacitive loads. If capacitors with acapacitance >1F are connected, the unit might charge the capacitor in an intermittent mode.
At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s.
After this, the output 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.
The device is equipped with a “Single Use / Parallel Use” feature, which can be selected on the front of the unit. The“Parallel Use” mode regulates the output voltage in such a manner that the voltage at no load is approx. 4% higher
than at nominal load. This achieves a load sharing between power supplies when they are connected in parallel.

The device has an integrated Power Supply Condition Display (PSCD). It
shows all the different power supply condition values on the front of the
PSU for condition monitoring and easy analysis of power errors. Whenswitched on, all LED segments of the PSCD light up for 2 seconds to indicate
the full functionality of the display. At the next turn-on procedure, thePSCD shows the menu of the last turn-off sequence.

The PSCD has two operating modes:
The Real-Time Data Mode provides the concurrent condition values of the PSU on Page 1.

The Recorded Data Mode continuously records min./max. condition values for analysis and monitoring purposes on
Page 2.
To start a new cycle of analysis the recorded data can be reset to the concurrent condition values (see To reset
recorded data). For a more in-depth analysis, PEAK values of input voltage parameters can also be displayed andrecorded (see Display R.M.S./PEAK values).

If all errors are cleared, Alarm turns off and the PSCD returns to thepreviously selected display mode. In case of an output overload, thismight last up to 18 seconds (due to HiccupPLUS-Mode)

10. REMOTE ON / OFF FUNCTION
This feature enables the output to switch off by signal input.
A link between pin 15 and 16 turns the power supply off. Pin 15 is referenced to the (-) output
voltage.
When multiple power supplies are connected in parallel, pin 15 and pin 16 are also allowed tobeparalleled to control all units with the same switch or transistor.

16. 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.

17. MTBF
MTBF stands for Mean Time Between Failures, 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.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

21. DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground.
The output is insulated to the input by a double or reinforced insulation.
Type and routine tests are conducted by the manufacturer. Field tests may be conducted in the field using theappropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all inputterminals 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.
We recommend that either the + pole or the – pole shall be connected to the protective earth system. This helps to
avoid situations in which a load starts unexpectedly or cannot be switched off when unnoticed earth faults occur.

decoupled by utilizing MOSFET technology. Using MOSFETs instead of diodes
reduces the heat generation and the voltage drop between input and output. The
YR20.242 does not require an additional auxiliary voltage and is self-powered
even in case of a short circuit across the output.
Due to the low power losses, the unit is very slender and only requires 32mm
width on the DIN rail.
The YR20.242 can be used for N+1 and 1+1 redundancy systems.
Further information and wiring configurations can be found in chapter 26.6.

25.3. YR20.246 - REDUNDANCY MODULE WITH AUTOMATED LOAD SHARINGThe YR20.246 is equipped with two input channels, which are individually

The YR20.246 is optimized for 1+1 redundancy systems.
Compared to the YR20.242, the YR20.246 is featured with an automated load
sharing between the connected power supplies. The YR20.246 monitors thefunction of the redundancy circuitry and provides a signal in case of too high ofoutput current, which could prevent redundancy, if one power supply fails.

26. APPLICATION NOTES
26.1. 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. 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 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 overcurrent 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 three examples show typical voltage dips for resistive loads:
Fig. 26-1 20A peak current for 50ms, typ.
(2x the nominal current)

Fig. 26-2 50A peak current for 5ms, typ.
(5x the nominal current)

Fig. 26-3 30A peak current for 12ms, typ.
(3x the nominal current)

Please note: The DC OK relay might trigger when thevoltage dips more than 10% for longer than 1ms.

26.2. 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 24V 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 24V 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.

26.3. CHARGING OF BATTERIESThe power supply can be used to charge lead-acid or maintenance-free batteries. Two 12V SLA or VRLA batteries areneeded in series connection.
Instructions for charging batteries:a)

Use only matched batteries when putting 12V types in series.

b)

Ensure that the ambient temperature of the power supply stays below 40°C.

c)

Use a 30A or 32A circuit breaker or a blocking diode between the power supply and the battery.

d)Ensure that the output current of the power supply is below the allowed charging current of the battery.

e)

The return current to the power supply is typically 3.5mA. This return current can discharge the battery when the
power supply is switched off except in case a blocking diode is utilized.

f)

Set the device into “Parallel Use” mode and adjust the output voltage, measured at no load and at the battery
end of the cable, very precisely to the end-of-charge voltage of 27.8V at 10°C, 27.5V at 20°C, 27.15V at 30°C and
26.8V at 40°C ambient temperature.

26.4. SERIES OPERATION
Devices 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 must be installed with a protection against touching.
Avoid return voltage (e.g. from a decelerating motor or battery) which isapplied to the output terminals.

Devices can be paralleled to increase the output power. The output voltage ofall power supplies shall be adjusted to the same value (±100mV) in “Single

with the factory settings. After the adjustments, set the unit to “Parallel Use”
mode, in order to achieve load sharing. 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.
The ambient temperature is not allowed to exceed +60°C.

If more than three units are connected in parallel, a fuse or circuit breakerwith a rating of 15A or 16A is required on each output. Alternatively, a diode or redundancy module can also be
utilized.
Energize all units at the same time. It also might be necessary to cycle the input power (turn-off for at least fiveseconds), if the output was in overload or short circuits and the required output current is higher than the current of
one unit.
Keep an installation clearance of 15mm (left / right) between two devices and avoid installing devices on top of eachother. Do not use devices in parallel in mounting 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.

26.6. PARALLEL USE FOR REDUNDANCY
1+1 Redundancy:
Devices can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain
amount of extra power to support the load in case one device fails. The simplest way is to put two devices in parallel.
This is called a 1+1 redundancy. In case one device fails, the other one is automatically able to support the load current
without any interruption. It is essential to use a redundancy module to decouple devices from each other. This
prevents that the defective unit becomes a load for the other device and the output voltage cannot be maintained any
more.
1+1 redundancy allows ambient temperatures up to +70°C.
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple devices.
Recommendations for building redundant power systems:- Use separate input fuses for each device.
- Use separate mains systems for each device whenever it is possible.
- Monitor the individual devices. Therefore, use the DC OK signal of the device.
- It is desirable to set the output voltages of all devices to the same value (± 100mV) or leave it at the factory setting.
- Set the devices into “Parallel Use” mode.
N+1 Redundancy:
Redundant systems for a higher power demand are usually built in a N+1 method. E.g. four devices, each rated for 10A
are paralleled to build a 30A redundant system.
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
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 devices in parallel in mounting orientations other than the standard mounting orientation or in any othercondition, where a derating of the output current is required.
For N+1 redundancy the ambient temperature is not allowed to exceed +60°C.
Wiring examples for 1+1 and n+1 redundancy:

supplies and redundancy modules

In the following test setup, the device is placed in the middle of the box, no other heat producing items are inside thebox. The load is placed outside 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.
