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
操作
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.
