The work principle of the DC system
AC-to-DC Power Conversion
In normal operating mode, the AC power distribution unit channels grid electricity to the high-frequency rectification modules. These modules efficiently convert the alternating current into direct current, simultaneously charging the battery system and supplying stable DC power to the connected load through the DC distribution network. This seamless AC-to-DC conversion ensures uninterrupted operation, making the system well-suited for mission-critical applications requiring a reliable and consistent power supply.
AC power loss working state:
In the event of an AC grid outage, the system seamlessly transitions to battery backup mode. As the rectifier modules cease operation, the battery pack immediately takes over powering the connected DC loads without interruption. A monitoring module tracks the battery's discharge voltage and current in real-time, triggering alarms when the set end-of-discharge threshold is reached. Simultaneously, the module processes and displays data from the power distribution monitoring circuits, providing comprehensive status updates during the grid failure.
