LP-1W4S Single Element Watt Transducer

The LP-1W4S single element watt transducer converts ac current and voltage signals into a dc output signal proportional to the active power flowing in the circuit.

The transducer is designed for 3 phase 4 wire systems with a balanced load.
The output of the transducer is unidirectional only.

Ordering information: LP-1W4S, inputs including CT & VT ratios, output, calibration, power supply.
Example: LP-1W4S, inputs 250/5A 400V, output 4-20mA, 0-200kW, 230Vac supply
