1+1 Redundancy Use of two identical power supplies in parallel to provide continued
operation following most failures in a single power supply.
The two power supply outputs should be isolated from each other
by utilizing diodes or other switching arrangements.
E.g. two 20A power supplies are needed to achieve a 20A redundant
system.
N+1 Redundancy Use of three or more identical power supplies in parallel to provide
continued operation following most failures in a single power supply.
All power supply outputs should be isolated from each other
by utilizing diodes or other switching arrangements.
E.g.: To achieve a 80A redundant system, five 20A power supplies
are needed in a N+1 redundant system.

immediately turn power off and send the device to the factory for inspection.
The device is designed, tested and approved for branch circuits up to up to 30A (UL) or 32A
(IEC) without additional protection device. If an external fuse is utilized, do not use circuit
breakers smaller than 10A B- or C-Characteristic to avoid a nuisance tripping of the circuit

8 Output
The output provides a SELV/PELV/ES1 rated voltage, which is galvanically isolated
from the input voltage. The output of the devices includes a decoupling MOSFET for building
1+1 or N+1 redundant power supply systems.
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 >1F are connected to the output, the unit might charge the capacitor
in the Hiccup mode.
The device is featured with a soft output regulation characteristic in order to achieve
current share between multiple devices when they are connected in parallel. The soft output
regulation characteristic regulates the output voltage in such a manner that the voltage
at no load is approx. 4% higher than at nominal load.

Load impedance 10mOhm, see Figure 8.2.
Output capacitance typ. 8 000μF 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.
1This current is also available for temperatures up to +70°C with a duty cycle of 10% and/or not longer than 1 minute every 10 minutes.
2The fuse braking current is an enhanced transient current which helps to start heavy loads or to trip fuses on faulty output branches.
The output voltage stays above 20V. See chapter 26.1 for additional measurements.
3At 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. See Figure 8.2.
