LP-1W1S Single Phase Watt Transducer

The LP-1W1S single phase watt transducer converts an ac current and voltage signal into a dc output signal proportional to the active power flowing in the circuit.

The transducer is designed for single phase systems.
The output of the transducer is unidirectional only.

Ordering information: LP-1W1S, inputs including CT & VT ratios, output, calibration, power supply.
Example: LP-1W1S, inputs 250/5A 230V, output 4-20mA, 0-100kW, 230Vac supply
