Note:
For some models of powered devices, the control
pin of the RPS500-A3 can be controlled through a
special cable to support hot backup of power
supply. Namely, when the power supply systems
of the powered devices operate normally, the
RPS unit also provides part of the power feed to
the devices; when the power supply system of a
powered device fails, the RPS unit becomes an
independent power supply system to feed that
powered device.
2.2 Features
The RPS500-A3 can provide selective DC
outputs. Depending on the connected DC output
cable(s), the RPS unit can p12 VDC or –50

powered device.
Note:
As optional parts for the RPS500-A3, different
types DC output cables are available depending
on the requirement of the powered device. For
details about the DC output cables, please
