Chinese wholesale Dual Sided Power Meter - JSY-MK-138 12 channel mutual inductance electric energy metering module – JIAN SI YAN Detail:

Description

Jsy-mk-138 12 way mutual inductance electric energy metering module can be widely used in energy-saving transformation, electric power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries to monitor the current and power consumption of AC equipment.

Features

1. Collect 12 AC parameters, including three-phase or single-phase voltage, current, power, frequency, electric energy and other electrical parameters.

2. RS-485 communication interface with one ESD protection circuit adopts MODBUS-RTU protocol, which has good compatibility and is convenient for programming.

3. Electrical insulation withstand voltage 2000vac.

4. Wide voltage operation AC80 ~ 265V.

5. Multiple specifications can be selected, single turn through core PCB fixed or open transformer, which is convenient and easy to use.

6. It can be changed and customized according to customer requirements.

Technical Parameter

1. Single phase AC input
