Parallel operation
Devices of the same type can be connected in parallel to
increase both redundancy and power. By default upon
delivery, no further adjustments are required.
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 symmetrical current distribution we recommend
that all cable connections from the power supply unit to the
busbar are the same length and have the same cross section.
Depending on the system, for parallel connection of more
than two power supplies a protective circuit should be
installed at each individual device output (e.g., decoupling
diode, DC fuse or circuit breaker). This prevents high return
currents in the event of a secondary device fault.
Redundant operation

Redundant circuits are suitable for supplying systems, which
place particularly high demands on operational safety. If a
fault occurs in the primary circuit of the first power supply unit,
the second device automatically takes over the complete

power supply without interruption, and vice versa. For this
purpose, the power supply units to be connected in parallel
must be large enough that the total current requirements of all
loads can be fully met by one power supply unit. External
decoupling diodes are required for 100% redundancy (TRIO-

For n parallel connected devices, the output current can be

is used when extending existing systems. A parallel

Otherwise, the load should be divided between individual
devices that are independent from one another.
A maximum of five devices can be connected in parallel.
