Wireless temperature sensor



Wireless temperature measurement module

Communication power collection terminal
ZRZD3 is an intelligent AC power parameter acquisition module that can be used for multi circuit power parameter monitoring. Collecting three-phase voltage, 3-9 current, active power, reactive power, apparent power, power factor, frequency and other electrical parameters in three-phase power lines, the module has RS-485 communication interface, convenient and fast wiring method, which is very suitable for low-voltage distribution online monitoring system renovation projects. It does not require changing the distribution equipment's primary line, and can be installed without power outage. It is easy to disassemble and maintain, and can meet various application needs.
