Single-phase electric energy meter KET-PMM-301

DIN rail50 HzModbus

The KET-PMM-301 is a single-phase energy meter with LCD display and integrated keypad. It is particularly suitable for active energy measurement and cost allocation in applications up to 80 A (direct connection). It integrates the measurement of all power parameters (such as current, voltage, active power, reactive power, apparent power, frequency, power factor, etc.). It has the ModBUS-RTU protocol with RS485 interface to meet communication network management requirements.
