YZIB5Z Series Intelligent DC Miniature Circuit Breaker is suitable for low-voltage power grid lines with a rated DC voltage of 48V/250V (customizable) and a rated current up to 63A/100A (customizable). It integrates comprehensive protection, high-precision measurement, control, and communication functions, and is equipped with RS485 communication mode. Cooperating with an intelligent gateway, it can upload real-time data, operating status, line faults, alarms and other information to the electrical safety Internet of Things supervision platform in a timely manner. This realizes data monitoring, hidden danger management, energy consumption management and power consumption optimization of the power distribution system, effectively improves the comprehensive perception ability of the line, and enhances the safety and reliability of power supply.

DC/DC storage battery capacity verification technology is an "energy feedback type" capacity verification technology developed to solve the pain points of traditional capacity verification. It realizes on-line constant current discharge and charging of storage batteries through DC/DC boost-buck circuits without detaching from the system, reducing the impact on power supply continuity. DC/DC storage battery capacity verification technology adopts high-frequency DC/DC modules (the main core is boost circuit and constant current charging module), contactors, diodes and other components, and its working states include three modes: standby floating charge, capacity verification discharge and constant current charging. In the standby floating charge state, the storage battery is directly connected to the system; during capacity verification discharge, the DC/DC boost circuit raises the storage battery voltage to be higher than the DC bus voltage, making the storage battery supply power instead of the rectifier; after discharge, it automatically switches to constant current charging to restore the storage battery capacity.
