6. OUTPUT
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.
The output 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 thecapacitor 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.

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 13V), the power supply delivers continuous output current for 1s. After this, the output is switched off forapprox. 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, thedevice will operate normally. See Fig. 6-3.

7. HOLD-UP TIME
The hold-up time is the time during which a power supply’s output voltage remains within specification following the loss of input
power. The hold-up time is output load dependent. At no load, the hold-up time can be up to several seconds. The green DC OK LED is
also on during this time.

13. 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 and is calculated according to thecapacitor’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 adevice. 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 thatstatistically 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.

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.
We recommend that either the + pole or the – pole shall be connected to the protective earth system. This helps to avoid situations inwhich a load starts unexpectedly or can not be switched off when unnoticed earth faults occur.

The device is equipped with two 10A nominal input channels, which are individually decoupled by utilizing diodetechnology. The output can be loaded with a nominal 20A continuous current.
The device does not require an additional auxiliary voltage and is self-powered even in case of a short circuit acrossthe output.
For a safe and vibration resistant wiring, the device is equipped with time saving quick connect spring clamp
terminals.
The unit is very narrow and only requires 32mm width on the DIN rail.
See chapter 23.5 for wiring information.

22.3. YR20.242 - REDUNDANCY MODULEThe 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. Dueto 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 acrossthe output.

22.4. YR20.246 - REDUNDANCY MODULE WITH AUTOMATED LOAD SHARINGThe YR20.246 is a dual redundancy module, which can be used to build 1+1 redundant systems.
The device is equipped with two input channels, each rated for 10A for ambient temperatures up to +70°C and are
individually decoupled by utilizing MOSFET technology. The inputs can also be operated up to 12A 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. Dueto these advantages, the unit is very narrow and only requires 32mm width on the DIN rail.

22.5. UF20.241 BUFFER MODULEThe UF20.241 buffer module is a supplementary device for DC 24V power supplies. It delivers power to bridge
typical mains failures or extends the hold-up time after the AC power is turned off.
When the power supply provides a sufficient voltage, the buffer module stores energy in the integrated
electrolytic capacitors. When the mains voltage is lost, the stored energy is released to the DC-bus in a
regulated process.
The buffer module can be added in parallel to the load circuit at any given point and does not require any
control wiring.
One buffer module can deliver 20A additional current and can be added in parallel to increase the output
ampacity or the hold-up time.

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 breakerneed 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 three examples show
typical voltage dips for resistive loads:

23.2. CHARGING OF BATTERIESThe power supply can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VRLA batteries are needed in seriesconnection.
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 for mains voltage of AC 120V or higher and 35°C for amains voltage of AC 100V.

c)

Use a 10A 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 8mA. This return current can discharge the battery when the power supply isswitched off except in case a blocking diode is utilized.

f)

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 27.8V at 10°C, 27.5V at 20°C, 27.15V at 30°C and 26.8V at 40°C ambient temperature.

23.3. SERIES OPERATION

Input

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 installedwith a protection against touching.
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 andavoid installing the power supplies on top of each other. Do not use power supplies inseries in mounting orientations other than the standard mounting orientation.

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 thedevices 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 ratingof 10A is required on each output. Alternatively, a diode or redundancy module can also
be utilized.

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).

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 caseone device fails, the other one is automatically able to support the load current without any interruption. It is essential to use aredundancy module to decouple devices from each other. This prevents that the defective unit becomes a load for the other device andthe 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 5A are paralleled tobuild a 15A 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.
