Overview 功能简介
H3C PSR450 power module series include PSR450-12A, PSR450-12A1, PSR450-12AHD, and
PSR450-12D. The PSR450-12A, PSR450-12A1, and PSR450-12AHD power modules support AC and
high-voltage DC inputs, and the PSR450-12AHD supports 240V/336V high-voltage DC input. The
PSR450-12D supports DC input. They can provide a maximum output of 450 W. The PSR450-12A
provides power module-side intake and port-side exhaust airflows. The PSR450-12A1, PSR450-
12AHD, and PSR450-12D provides port-side intake and power module-side exhaust airflows.
PSR450系列电源包括PSR450-12A、PSR450-12A1、PSR450-12AHD和PSR450-12D这四款电源。
其中PSR450-12A、PSR450-12A1、PSR450-12AHD均支持交流和高压直流输入、直流输出的交流电
源模块，其中PSR450-12AHD支持240V/336V高压直流输入；PSR450-12D是直流输入、直流输出的直
流电源模块。在这四款电源模块中，PSR450-12A是电源侧进风，端口侧出风的吹风电源模块；
PSR450-12A1、PSR450-12AHD、PSR450-12D是端口侧进风，电源侧出风的抽风电源模块。
The power modules provide the following features:
PSR450系列电源模块特点：
Self-protection—The power modules provide output overvoltage, output current limiting, output short
circuit, overtemperature, and input undervoltage protections. See the following table for the protection
and auto-recovery features of the power modules.支持保护功能—支持输入过流保护、输出限流保护、输
入欠压保护、输出过压保护、输出短路保护、过温保护等功能
Redundancy—Two power modules can be connected in parallel to achieve 1+1 redundancy and load
sharing.支持冗余备份—支持双电源模块并联工作，以实现电源系统1+1备份，并且备份电源间具有负载
均流功能
Hot swapping—You can remove one of the two power modules in 1+1 redundancy while the device is
operating.支持热插拔—在设备正常工作的情况下，可对1+1冗余备份电源系统中的某个电源模块进行插拔
