Functions 功能简介
The PSR250-12A and PSR250-12A1 power modules support AC and high-voltage DC inputs. They
can provide a maximum output of 250 W. The PSR250-12A provides power module-side intake and
port-side exhaust airflows, and the PSR250-12A1 provides port-side intake and power module-side
exhaust airflows.
PSR250-12A和PSR250-12A1均是交流或高压直流输入、直流输出的电源模块；最大输出功率可达
250W。两款电源模块的区别是：PSR250-12A是电源侧进风，端口侧出风的吹风电源模块；PSR250-
12A1是端口侧进风，电源侧出风的抽风电源模块。
The power module provides the following features:
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。
