Parallel operation
Devices of the same type can be connected in parallel to en-
able both redundancy and an increase in efficiency. No other
alignment is necessary when in the state of delivery. If the
output voltage is adjusted, a uniform distribution of power is
guaranteed by setting all parallel operated power supply
units to exactly the same output voltage. To ensure symme-
trical distribution of power, we recommend designing all
cable connections from the power supply unit to a busbar of
the same length and with the same conductor cross section.
The system makes it advisable to install a protective circuit
at the output of each device when more than two power sup-
ply units are connected in parallel (e.g. decoupling diode or
DC fuse). This prevents high reverse feed currents in the
event of a secondary device fault.

Redundant circuits are suitable for the supply of systems
which make especially high requirements on the operational
safety. If a fault occurs in the primary circuit of the first power
supply unit, the second device automatically takes over the
+

entire power supply, without interruption, and vice versa. For
this reason, the power supply units to be connected in paral-
lel are dimensioned in such a way that the total current re-
quirement of all consumers can be completely covered by
one power supply unit. 100% redundancy makes external

For n parallel connected devices, the output current can be
increased to n x I N . Parallel connection to increase efficiency
is used for the expansion of existing systems. It is advisable
to use parallel connection if the power supply unit does not

cover the current requirement of the most powerful consu-
mer. Otherwise the consumers should be spread among in-
dividual devices independent of one another. A maximum of
five devices can be connected in parallel!
