12 Channels Mutual Inductance Power Meter Module &Electrical Parameters Collector
The JSY-MK-138 12-channel mutual inductance power metering module can collect, measure, and transmit AC parameters, such as three-phase AC voltage, current, power, power factor, frequency, electrical quantity etc. It can also measure 12 single-phase AC voltage, current, power, power factor, frequency, electrical quantity etc. It provides 1 RS-485 communication interface and separate power supply, MODBUS-RTU protocol, has excellent cost-effectiveness.
JSY-138 can be widely used in energy-saving renovation, power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries to monitor the current and power consumption of AC equipment.
Features:
1. Capture 12 channels AC electrical parameters such as three-phase and single-phase voltage, current, power, power factor, frequency and energy etc.
2. Adopting dedicated measurement chips and effective value measuring methods, with high measurement accuracy.
3. With one RS-485 communication interface.
4. Modbus-RTU protocol, which has good compatibility and is convenient for programming.
5. RS-485 communication interface with ESD protection circuit.
6. Wide working voltage AC80~265V.
7. High isolation voltage, withstand voltage up to DC2000V.
8. Solid-core and split-core current transformers optional.
9. Can configure one voltage input randomly according to the actual wiring situation.
