voltage, current,active power, reactive power, power factor, power grid frequency, active power, reactive power.
Multi-function electric instrument can high precision measurement three-phase power grid system all commonly used electricity parameters: the three-phase voltage, three phase current and active power, reactive power, power factor, power grid frequency, active power, reactive power, and with a communication interface and electricity pulse output function. The MODBUS - RTU communication protocol, realize the LED display and remote RS - 485 digital communication. With convenient installation, wiring simple, maintenance is convenient, and the quantities of small, field programmable set the input parameters, etc., and will be able to accomplish and the different PLC and indusrial control computer network communication.
