HC model SPWK watt / var transducer is compact, designed to be a very accurate mode with DC 1mA output directly proportional to an AC rated input. output of watt & var are isolated each other to eliminate ground effect. For utility, the units are useful including industry, laboratories & process control requiring accurate power or energy measurements.
- 2 models available
- 3 phase 3 wires / 2 elements
- 3 phase 4 wires / 3 elements
- Dual isolated output watt / var eliminating ground loops effect
- Accuracy of reading base 0.25% reading + 0.02% ro
