INTEGRATING POWER/ REACTIVE POWER TRANSDUCER

INTEGRATING POWER TRANSDUCER
WHP-83A-□
INTEGRATING REACTIVE POWER TRANSDUCER
WVHP-83A-□■ Use
This product converts power/reactive power of single phase/ 3-phaseand 3-phase 4-wire to proportional pulse output/ analog output.

■ Features
1. Power/reactive power can be measured accurately in distortedwave.
2. Integrating power can be measured in short period of time such as
20-30 seconds.
3. Variety of pulse output signal method can be selected.
4. Product with analog output (option) can be manufactured.
Analog output: with line surge (2,000A 8/20µs) protection andsignal is outputted in remote place.
5. As output limiter circuit is equipped, output can be limited toapprox. 1.5 times of rated value even at an excessive input.
