Overview
The PSR150-A1 is an AC-input and DC-output power module. The
PSR150-D1 is a DC-input and DC-output power module. Both power
modules provide an output voltage of 12 V and a maximum output of 150
W.
These power modules have the following features:
•
Provide output overvoltage, short-circuit, overcurrent, and
overtemperature protections. See
for the protection and
auto-recovery features of the power modules.
•
Two power modules can be connected in parallel to achieve 1+1
redundancy and load sharing.
•
Hot swappable. When you hot swap a power module, make sure the
device can operate correctly with the remaining power modules.
