Redundant Power Systems

DuraComm’s redundant power models incorporate a second module in passive (N+1) or active (1+1) configurations. DC ok/fail contacts for each model on the back of the unit.


N+1 passive redundancy models:  the second power module is in standby mode until the primary module fails

– HE1U-2524-N+1
– HE1U-1248-N+1
– RLP-4012-N+1
– RLP-2024-N+1
– RLP-1048-N+1

1+1 active redundancy models: these units have independent power modules in a parallel, load sharing configuration.  De-rate the total current output of each unit by half for 1+1 redundant output capacity.
