H3C PSR300-12A & PSR300-12D
Series Power Modules
User Manual-6PW105
BOM: 3101A12G
Overview
Introduction
The PSR300-12A series (PSR300-12A, PSR300-12A1, and
PSR300-12A2) are AC-input and DC-output power modules.
The PSR300-12D series (PSR300-12D1 and PSR300-12D2) are
DC-input and DC-output power modules. These power modules
provide 12 VDC voltage and a maximum output power of 300 W.
The power modules support 1+1 redundancy an d load sharing and
are hot swappable.
The power modules provide overvoltage, short circuit, overcurrent,
and overtemperature protections.
• It shuts down and latches off when an overvoltage, short circuit,
or overcurrent condition occurs.
To restore the operation, reconnect the power cord . Make sure
you turn off the power switch on the po wer module when you
disconnect and reconnect the power cord.
• It shuts down when an overtemperature condition occurs and
automatically restores operation after the temperature
decreases to the acceptable range.
