6. OUTPUT
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.
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 > 0.3F are connected to
the output, the unit might charge the capacitor in an intermittent mode.
The output is electronically protected against overload, no-load and short-circuits. In case of a protection event,
audible noise may occur.

The unit 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 absorbing energy can be calculated according to
the built-in large sized output capacitor.
1) PowerBoost: This power/ current is continuously allowed up to an ambient temperature of +45°C. Above +45°C, do not use this power or
current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
2) At heavy overloads (when output voltage falls below 7V), the power supply delivers continuous output current for 1s. After this, the output
is switched off for approx. 9s 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.

13. 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.

14. 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.
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 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.

safety critical situations, which can happen e.g.
when ambient temperature is too high, ventilation
is obstructed or the derating requirements are not

18. 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 the
appropriate 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.

22.2. YR20.242 - REDUNDANCY MODULE
The YR20.242 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems.
The device is equipped with two input channels, each rated for 20A for ambient temperatures up to
+70°C and are individually decoupled by utilizing MOSFET technology. The inputs can also be
operated up to 24A when the ambient temperature does not exceed +45°C.
The output can be loaded with nominal 20A at +70°C or 24A at 45°C continuous current.
Using MOSFETSs instead of diodes reduces heat generation, losses and voltage drop between input
and output. Due to these advantages, the unit is very narrow and only requires 32mm width on the
DIN rail.
The device does not require an additional auxiliary voltage and is self-powered even in case of a short
circuit across the output.
See chapter 23.5 for wiring information.

23. APPLICATION NOTES
23.1. 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 load
branches 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 two examples show typical voltage dips for resistive loads:
Fig. 23-1 20A peak current for 50ms , typ.
(2x the nominal current)
Fig. 23-2 50A peak current for 5ms , typ.
(5x the nominal current)
Fig. 23-3 30A 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.

23.2. CHARGING OF BATTERIES
The power supply can be used to charge lead-acid or maintenance free VRLA batteries.
Instructions for charging batteries:
a)
b)
c)
d)
e)
Ensure that the ambient temperature of the power supply stays below 40°C for mains voltage of AC 120V or
higher and 35°C for a mains voltage of AC 100V.
Use a 15A or 16A circuit breaker or a blocking diode between the power supply and the battery.
Ensure that the output current of the power supply is below the allowed charging current of the battery.
The return current to the power supply is typically 8mA. This return current can discharge the battery when the
power supply is switched off except in case a blocking diode is utilized.
Set the output voltage, measured at no load and at the battery end of the cable, very precisely to the end-ofcharge voltage. Set the output voltage, measured at no load and at the battery end of the cable, very precisely to
the end-of-charge voltage. The voltage should be set to 13.9V at 10°C, 13.75V at 20°C, 13.6V at 30°C and 13.4V at
40°C ambient temperature.
23.3. 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 is
applied to the output terminals.

Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple devices.
23.4. PARALLEL USE TO INCREASE OUTPUT POWER
Devises can be paralleled to increase the output power. The output voltage
shall be adjusted to the same value (±100mV) with the same load conditions on
all devices, or the devices can be left with the factory settings.
The ambient temperature is not allowed to exceed +40°C.
If more than three devices are connected in parallel, a fuse or circuit breaker
with a rating of 15A or 16A is required on each output. Alternatively, a diode
or redundancy module can also be utilized.
Energize all devices 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 short circuits and the required output current is higher than the current of
one unit.

23.5. 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.
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 devices.
Keep an installation clearance of 15mm (left / right) between two devices and avoid installing the devices on top of
each other.
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.
For N+1 redundancy the ambient temperature is not allowed to exceed +40°C.

23.7. USE IN A TIGHTLY SEALED ENCLOSURE
When the device is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than
outside. In such situations, the inside temperature defines the ambient temperature for the device.
In the following test setup, the device is placed in the middle of the box, no other heat producing items are inside the
box. 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.
