DC panel used in large, middle and small power generating plant or substation, output DC source for the ON/OFF operation, relay protection, auto control, lighting tor high voltage switches at normal status or fault status. The reliability of the DC panel is essential for auxiliary power sources in substations and power plants.
This series features small size, high efficiency, module design n+1 heat redundancy backup, and high reliability. Utilizing advanced resonant voltage dual-loop control and "four remote operations" via RS-485 and RS232 interfaces, it excels over traditional power sources.
Automatically switches on/off according to voltage for closing operations using stepless or step voltage drop devices reliably.
Monitors running parameters of each module, including AC source voltage, battery discharging current, and insulation parameters, uploading them to a host machine.
Includes surge protection, output over-voltage/current limiting, short circuit protection, and over-temperature protection.
Flexible combination of power modules to match battery capacities from 10Ah to 3000Ah, ensuring continuous operation even if one module fails.
Utilizes Valve Regulated Lead Acid Batteries that do not require acid or water refills, managed by a smart controller.
