ST420M Series Intelligent Network Power Meter
Product overview
ST420M1(ST420M3) series single-phase (three-phase) intelligent network power meters are used for measurement monitoring and control of power distribution systems. The instrument can measure voltage, current, active power, reactive power, apparent power, power factor, frequency and active power. There are 4 (6) switch inputs for monitoring the switch status, two relay outputs for controlling the switch, and 1 (2) analog output for DCS system or industrial monitoring equipment. ST420M series instruments combine precise measurement, intelligent multi-function and simple man-machine interface.
The ST420M series of intelligent network power meters can be used in data acquisition units of intelligent power distribution systems or enterprise process automation systems. Remote monitoring and management of equipment operation can be realized through RS485 Modbus-RTU communication port.
Due to the use of true effective value measurement, ST420M series intelligent network power meter is suitable for the measurement of high-order harmonics due to voltage and current distortion caused by nonlinear loads (such as frequency converters, electronic ballasts, computers, etc.).
