Single-phase energy meter up to 80 A
The KET-PMM-301 is a single-phase energy meter with LCD display and integrated keypad.
It is particularly suitable for active energy metering and cost allocation in applications up to 80 A (direct insertion).
Integrates 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.
