OVERVIEW
Redundant power units provide an easy to install and use method of giving you the peace of mind required
when managing safety tolerant systems.
This Redundant Power Unit (SMCRPU14) can supply 600 Watts of backup power to four switches in the event
of an AC loss or failure of an internal power supply. It ships with four DC Backup Power Cords included (IEC
connectors). Thermal overload protection prevents the RPU from overheating if a thermal overload occurs.
Over-voltage protection shuts down an output channel if the voltage exceeds a preset threshold whereas
over-current protection shuts down the RPU if the output load exceeds a preset threshold. Short-circuit
protection prevents the RPU from being damaged from a short circuit on any output channel. Four status in-
dicators for Link, Activity, Fan, Thermal, and Power are located on the RPUs front panel. While the AC supply
and DC backup receptacles are located on the RPUs rear panel. The SMCRPU14 can be mounted in a standard
19-inch equipment rack(brackets included) or on a fl at surface.
