Three-phase energy meter, direct 80A, 4M, S0, MID. Energy meter for four-quadrant measurement with the following accuracy classes: Active energy Class B according to DIN EN 50470-3, Active power Class 1 according to IEC 62053-21, Active power Class 1 according to IEC 61557-12, and Reactive power Class 2 according to IEC 62053-23. The bidirectional meter is factory MID certified (a sealing kit is included in the delivery) and features a resettable partial meter. Suitable for measuring energy consumption and energy delivery in all network systems. Two tariff measurements can be controlled via 230 V AC and output through two configurable pulse outputs. Digital display with backlighting for showing consumed and delivered active (kWh) and reactive energy (kvarh) for all tariffs. Additionally, real-time measurements for active power (kW), reactive power (kvar), apparent power (kVA), voltage (V), current (A), power factor, frequency (Hz), and tariff are displayed for each phase with a resolution of up to 9 digits including two decimal places. The pulse output provides measurement values for consumed and delivered active (kWh) and reactive energy (kvarh), as well as the consumed active energy (kWh) for Tariff 1 and Tariff 2. All measurement values and energy values for Tariff 1 and Tariff 2 can also be output via an IR interface. Wiring errors and connection errors are displayed, and the measurement data is periodically stored.
