Cabinet fan controller and cabinet temperature control system

According to the cabinet fan controller and the cabinet temperature control system, a switch power supply supplies power to a processor, the processor controls a switch control circuit to supply power to a fan, and according to setting of a temperature control mode setting module, operation of the fan is controlled through a fan control interface set on a shell; as the switching power supply is an AC/DC input dual-purpose power supply, the switching power supply can be applied to AC power supply occasions and DC power supply occasions, and compared with a single DC or single AC power supply scheme in the prior art, the switching power supply is wide in application range and convenient to apply. And moreover, a communication circuit is provided, so that a communication network can be realized, and the actual requirements of intelligent operation and maintenance can be met. 本实用新型提供一种机柜风扇控制器及机柜温控系统，其通过开关电源为处理器供电，其处理器控制开关控制电路为风扇供电，并根据温控模式设置模块的设置，通过壳体上的风扇控制接口组控制风扇运行；由于开关电源为交直流输入两用电源，所以可以适用于交流供电场合和直流供电场合，相比于现有技术的单直
