 EV100 Series Single-phase power network meters, power distribution systems for continuous monitoring. Each instrument can measure true RMS voltage, respectively, current, active power, reactive power, apparent power, power factor, frequency, active power and so on. All the way analog output for the DCS system or industrial monitoring equipment, four digital inputs for monitoring switch status, two relay outputs for control switch action. All data are available through the RS485 port with Modbus ? RTU protocol to read out.
