kWh meters, WQR96 MKII

Application The kWh meters types WQR96 MKII and WQ2R96 MKII are intended for energy measurement in single-phase and 3phase networks, providing a class 1.0 measurement of the imported or exported energy. The meters are microprocessorcontrolled and equipped with a 7-digit electromechanical counter, which retains the reading in case of supply voltage failure. The meters are furthermore equipped with one or two pulse outputs. The meters can be adapted to the applied current transformers. WQR96 MKII

Meter with a 7-digit register and one pulse output for measurement of one type of energy only (kWh or kvarh).

WQ2R96 MKII

Meter with two 7-digit registers and two pulse outputs for measurement of two types of energy (both kWh and kvarh imported or exported).

WQR96-x MKII

Meter with both a 7-digit register and one pulse output for energy measurement (kWh or kvarh) and a 90° instrument for simultaneous indication of the momentary power value (active or reactive).

WQR96-c MKII

Meter with both a 7-digit register and one pulse output for energy measurement (kWh or kvarh) and a 240° instrument for simultaneous indication of the momentary power value (active or reactive).
