The DC power supply monitoring device (HSC6880V2) adopts serial bus structure, decentralized control and centralized management mode. The organizational structure of its monitoring system is shown in Figure 1. Each functional module in the DC system is an intelligent unit with a CPU, and all have self-diagnosis capabilities; the communication between the module and the monitor is all serial communication; when any module fails, it will not affect the normal operation of other units, and the centralized monitor It can respond to the current faulty module through alarms in time. Advanced control logic and communication verification algorithm can ensure that the system will not malfunction under any interference environment

The HSC6882V2 battery inspection and acquisition module can detect the voltage of 31 batteries and upload the detected data through the RS485 communication port. It adopts the shape of a rail-mounted industrial control case, which is small in size and light in weight. It can be installed near the battery pack to achieve local acquisition of voltage and temperature. It has the advantages of simple wiring, strong anti-interference ability, and high acquisition accuracy.

CL6882M02 is an online battery inspection module designed for UPS, EPS, DC power supply, communication power supply and other systems. It can complete the monitoring and alarm functions of battery pack voltage, battery current, single battery voltage and battery ambient temperature.
