Single-phase energy meter, direct 40A, 1M, S0, MID. Energy meter for 4-quadrant measurement with the following accuracy classes: Active energy class according to DIN EN 50470-3, active power class according to IEC 62053-21, active power class according to IEC 61557-12, and reactive power class according to IEC 62053-23. A sealing kit is included in the delivery. Suitable for measuring energy consumption and energy delivery in all network systems. Digital display for showing consumed and delivered active energy in kWh. Additionally, real-time measurements for active power in kW, voltage in V, current in A, power factor, and frequency in Hz are displayed with a resolution up to decimal places. Active kWh and reactive energy kvarh are output via pulse. All measurement values and energy values are also output via an IR interface. Wiring errors and connection errors are indicated, and the measurement data is periodically stored. ECP140D.
