Three-phase power meter and counter for Rogowski coils - ModBUS RS485 communication. Includes a kit of Rogowski coils with 110mm diameter - Maximum current 1000A.

The KET-PMT-317.000 is the energy meter with a coil for measuring energy in KET-PMT-317.000 Rogowski energy meter in residential and industrial environments.
The advantages of this product are simple and convenient wiring, safe installation, cost savings in transformation, and improved efficiency for users.

It integrates the measurement of all power parameters (such as current, voltage, active power, reactive power, apparent power, frequency, power factor, etc.), multi-level electrical energy measurement, four-quadrant electrical energy measurement, harmonic analysis, electrical energy monitoring, and evaluation management.

It features the RS485 interface protocol, capable of meeting ModBUS-RTU communication network management requirements.

The LCD display is used to configure product parameters and check the status of the monitored system.

The power meter is supplied with a set of three Rogowski coils with variable diameter depending on the load to be monitored (see Order Codes table)
