LP-2V3 Three Phase var Transducer
LP-2V3H Three Phase var Transducer with kvarh Pulse Output

The LP-2V3 three phase var transducer converts ac current and voltage signals into a bi-directional dc output signal proportional to the reactive power flowing in the circuit.

The transducer is designed for 3 phase 3 wire systems
with an unbalanced load.
Optional output for scalable kvar-hour pulses. (LP-2V3H)

Ordering information: LP-2V3, inputs including CT & VT ratios, output, calibration, power supply.
Example: LP-2V3, inputs 250/5A 110V, output ±10mA, ±50kvar, 110Vdc supply
