TZ220AC-50 AC Intelligent Power Distribution Module

TZ220AC-50 AC Intelligent Power Distribution Module

The TZ220AC-50 AC intelligent power distribution module complies with the “SJ20668-1998 General Specification for Microcircuit Modules”. With the intelligent functions such as automatic protection and detection, this series of products also have good resistance to high and low temperature, vibration and impact, and is of small size, light weight and high reliability. It can replace the conventional power distribution method of AC contactor/relay + fuse/circuit breaker, and is suitable for single-phase AC power distribution circuit of new generation weapon system.
