Electricity Meter 3 Phase Measure Current Voltage Power Frequency Energy w/ LCD RS485 Communication

Electricity Meter 3 Phase Measure Current Voltage Power Frequency Energy w/ LCD RS485 Communication

Attention:
1. The accuracy of this meter is 0.5 level, that is to say, if the current you measure is 100A, the error will not exceed 0.5A, the voltage is the same;
2. The maximum straight-through measurement current is 5A, and the maximum current 9999KA can be measured with a transformer. The current transformation ratio can be set freely. For example, 100/5A can be used to set the CT ratio to 20, 3000/5 can be set to CT Transformation ratio is 600;
3. The maximum straight-through voltage is 750V, greater than 750V can be equipped with voltage transformers, the maximum can measure 9999KV, and its voltage transformation ratio can also be set by itself. For example, if you use a 1000/100V voltage transformer, you can set PT to 10 and use 20000/100V. Transformer can set PT to 200.
