3.8.1 Module Description
The PSU can be configured to provide one or two channels of regulated 48 VDC power.
The PSU features redundant inputs, allowing power to be supplied from two independent
240 VAC sources. The PSU can also be configured in a redundant output configuration
with an optional second rectifier module installed for each DC output. When two rectifier
modules are installed and operating normally, the failure of one module will not affect the
DC power output for that channel.
