LP-2W3 Three Phase Watt Transducer

The LP-2W3 three phase watt transducer converts ac current and voltage signals into a bi-directional dc output signal proportional to the active power flowing in the circuit.

The transducer is designed for 3 phase 3 wire systems
with an unbalanced load.

Ordering information: LP-2W3, inputs including CT & VT ratios, output, calibration, power supply.
Example: LP-2W3, inputs 500/5A 11kV/110V, output -10mA to 0 to +10mA,
-10MW to 0 to +10MW, 110Vdc supply

Note. The LP-2W3H pulse output version is no longer available.
