KPM53 Three phase smart digital power meter
KPM53 three phase smart digital power meter is used to measure three-phase electrical parameters, display, power statistics, power quality analysis, digital input / output and network communications in one. With high precision Class 0.5s, strong isolation, stable performance, anti-interference ability, etc.; the device also has a very strong expansion capabilities, such as monitoring of external switching action, 4-20mA analog output. Also the network management of the instrument can be realized through RS-485 / Modbus communication protocol.
