Application
1.Full digital design, AC sampling, human machine?interface is large LCD display.
2.Designed with friendly human care, module asse-mbly,flow-line figure
3.It can display power factor, voltage, current, active?power, reactive power, distortion rate of total voltage?harmonic waves, distortion rate of total current har-monic waves, frequency average value, and capacitor?switching status and etc.?
4.Parameter setting, to be instructed in Chinese?words and English, digit input.
5.Capacitor control modes, two kinds: three-phase?compensated together, combined compensation,?you can set the control modes through the menu
6.Two working modes: Hand compensation/Auto?Compensation
7.Parameter sampled is reactive power, it has the?function of measuring harmonics and protections.
8.The controller provides RS-485, MODBUS standard?communication port, used to connect with?intelligent switchgear system.
