RS485 Modbus Single-channel AC/DC Power Meter Voltage Current Power Energy Acquisition Module



Introduction

      CWT-JSY-MK-229 single-channel AC/DC collector is a highly integrated measurement and digital communication technology. It can complete the measurement, collection and transmission of DC electrical parameters. It can accurately measure DC voltage, current, power, electricity and other electrical parameters. It has a RS485 communication interface, completely isolated circuit, small volume and simple interface. It can be easily embedded into various equipment that need to measure DC power consumption and has excellent cost performance.

CWT-JSY-MK-229 AC/DC collector can be widely used in energy-saving transformation, AC/DC charging pile, electric power, communication, railway, transportation, environmental protection, petrochemical, steel and other industries, and used to remotely monitor the use of AC/DC equipment.
