Its working principle is that the AC power supply undergoes rectification, filtering
/conversion-related protection circuits and other links to output a stable DC voltage. It has dual overvoltage and overcurrent protection, and meets the performance requirements of intrinsic safety. Technical parameters Input rated voltage
