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 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.

Output voltage Nom. 24V

Adjustment range 24-28V Guaranteed value
Max. 30.0V This is the maximum output voltage which can occur at the clockwise end
position of the potentiometer due to tolerances. It is not a guaranteed
value which can be achieved.
Factory settings Typ. 24.1V ±0.2%, at full load and cold unit
Line regulation Max. 10mV Between 85 and 300Vac

Output capacitance Typ. 1 800µF Included inside the power supply
Back-feeding loads Max. 35V 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 13V), 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.

228 000h 271 000h 336 000h At 24V, 6A and 25°C

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 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.

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 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 in
which a load starts unexpectedly or can not be switched off when unnoticed earth faults occur.

The YR2.DIODE is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems.
The device is equipped with two 10A nominal input channels, which are individually decoupled by utilizing diode
technology. 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 across
the 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 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.

22.4. YR20.246 - REDUNDANCY MODULE WITH AUTOMATED LOAD SHARING

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. 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.
The device is equipped with an automated load sharing feature, which balances the load current between the two
input channels. It also monitors the function of the redundancy circuitry and provides a signal if the output current is too high, which
could prevent redundancy if one power supply fails. The signal also reports too low or too high input voltages.

22.5. UF20.241 BUFFER MODULE

The 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 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 three examples show
typical voltage dips for resistive loads:

23.2. CHARGING OF BATTERIES

The power supply can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VRLA batteries are needed 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 for mains voltage of AC 120V or higher and 35°C for a
mains 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 is
switched 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.

23.5. 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 5A are paralleled to
build 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.
