Data sheet
Short description
When failures might cause costly extensive downtimes, a design solution is a redundant power supply that uses several (N+1) identical power
supplies.
The redundancy module SLR01 is designed to create an N+1 redundancy
in combination with the PULS power supply SL40 or other 24...28V power supplies with an output current of up to 40A (max. 50A). One SLR01
is required for each power supply. The module decouples the output of
the connected power supply from the others so that in the event of
failure one power supply unit cannot overload the other units. A relaychangeover contact, picked up under normal conditions and dropped in
the event of failure, indicates the status of the connected power supply
unit.
A Dual Redundancy Module, SLR02, is available to provide redundancy
with two attached power supply units, each with an output current of
up to 30A (max. 35A). For smaller current values of 2.5A, 5A and 10A
PULS also offers the SLR2, SLR5 and SLR10 power supplies with integrated redundancy modules.
