4WAZMK-1 Bus Intelligent Relay Module

4WAZMK-1 is a serialized SSPC module product, which integrates 4 channels of 35A solid-state power output, and has 4 independent channels of emergency control. Various overcurrent protection and short circuit protection thresholds can be set within the range of its specification through software, which make it meet the power distribution needs of different working current devices in the intelligent power distribution system.


  • 4-way load
  • Emergency switch
  • Over current protection, short circuit protection
  • Current Detection
  • High output power
  • Small size and light weight
