Three-phase MID energy meter for active and reactive energy measurement with bi-directional metering for imported and exported energy, current (A), voltage (V), active power (kW), reactive power (kVAr), power factor (cos φ) and other electrical parameters. Connection via current transformers (CT). The device has an integrated communication module to the KNX bus.
The meter has four S0 pulse outputs for the transmission of imported and exported active and reactive energy data, which can alternatively be used for load control functions or for threshold monitoring of a maximum value. The device enables two- or four-tariff system management with switching of the active rate via a 230 Vac signal. Protection against manipulation is provided by sealable terminal covers. The device is designed for DIN rail mounting according to EN 60715 inside switchboards and control cabinets.
