Intelligent electrical measuring instruments are developed and produced in accordance with standards such as GB/T 22264.1-2008 "Installed digital display electrical measuring instruments - Part 1: General requirements for definitions" and GB/T 21705-2008 "Low voltage electrical quantity monitors". The AC part is suitable for AC single-phase or three-phase power systems and automation control systems that use AC sampling calculation technology to monitor voltage or current in the system; The DC part is designed for applications such as power station DC screens, solar power generation, and telecommunications base station DC systems. The instruments in this part can measure the voltage, current, power, forward and reverse electrical energy in the DC system. Supports direct signal input, current splitter input, and DC signal transmitter input.
This series of instruments has multiple expansion functions, such as external switch detection, relay output or alarm, RS485 communication, etc.
