6. OUTPUT
The output provides a SELV/PELV/ES1 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. The output can supply any
kind of loads, including unlimited inductive and capacitive loads. If capacitors with a capacitance >2F are connected,
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.

Back-feeding loads
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) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2-5s. After this, the
output is switched off for approx. 7s before a new start attempt with duration of 1s is automatically performed. This cycle is repeated as
long as the overload exists. If the overload has been cleared, the device will operate normally.

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 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.

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. ACCESSORY
22.1. PIRD20.241 REDUNDANCY MODULE
The PIRD20.241 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.
The unit is very narrow and only requires 39mm width on the DIN-rail.
See chapter 23.4 for wiring information.
22.2. 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.
For longer hold-up times the UF40.241 might also be an option.

23.2. SERIES OPERATION
Unit A
AC
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.

(see notes)
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple devices.
23.3. PARALLEL USE TO INCREASE OUTPUT POWER
Do not use the power supply in parallel to increase the output power.
23.4. PARALLEL USE FOR 1+1 REDUNDANCY
The device can be used to built 1+1 redundant systems.
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.

23.6. 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
than outside. In such situations, the inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
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.
