I. System overview
      CL6880MA is a product developed for the application of power integration system, which integrates the related detection and control functions of the AC and DC bus of the charging cabinet. It can be used as the overall monitoring of the integrated system with one charge and one battery, and can also be used as a sub-monitor of a large system with two batteries and two batteries or three batteries and two batteries.
      CL6880MA adopts integrated design, which simplifies system design to the greatest extent. Compared with the configuration screen monitoring system, CL6880MA×1=7inch configuration screen monitor×1+24VAuxiliary power×1+DB9Signal Adapter×1+RS232/RS485Protocol Converter×1+< /span>AC/DC integrated detection unit×1+IRIG-BTimer×1+Hall current sensor×2.
In addition,CL6880MAThe monitoring system adopts modular The design idea, combined with modular power distribution monitoring products, can flexibly meet diverse design requirements.
