The LED Multifunction digital meter with voltage, current, active power, reactive power, power factor etc. function is an ideal device for power quality monitoring. The meter has the function of simultaneously measuring current, voltage, frequency, active power, reactive power, apparent power, electric energy, power factor, etc. in the power grid. It is suitable for distributed detection of transformers, generator sets, capacitor banks and motors, and on-site monitoring of power grids and automation control systems. multifunction power meter with RS485
Multi-function power meters can also be used in factory automation and building automation. It can measure all the power parameters, and can be easily applied to the measurement and data recording of AC-opening and industrial power supply distributed measurement and control systems of various ranges. On the basis of our company's multi-function power meter, a simple monitoring system can be established by simply adding a central communication master display software based on IPC industrial computer. CE approved panel mount programmable switchboard LCD digital power meter
Multi-function power monitor can replace many traditional panel or digital measuring instruments (such as ammeter, voltmeter, power meter, power factor meter, frequency meter, etc.), which can greatly reduce system cost, facilitate field wiring and improve system reliability. three phase digital ammeter digital input output. The multi-function power monitor is equipped with a serial port (RS-485), which allows connection to an open-structure computer network; the Modbus-RTU communication protocol is used to facilitate computer programming or reading. LED Multifunction digital meter with voltage, current, active power, reactive power, power factor etc. function. low voltage switchgear use digital panel meter with RS485
