AC 380V Three Phase Multi-function Electric Meter

Availability:
Quantity:

Three-phase multi-function electric meter is to measure all three-phase electrical parameters: three-phase current, three-phase voltage, three-phase active power, combined phase active power, three-phase reactive power, combined phase reactive power, three-phase apparent power, combined phase Apparent power, three-phase power factor.


1. Real-time high-precision measurement of three-phase power factor, three-phase active power, three-phase reactive power, three-phase total power, electric energy and other parameters

2. Complete isolation of power supply, collection and communication, high reliability

3. Use transformers to collect current parameters to achieve high-power current collection
