An AC/DC power supply panel is an integrated power distribution cabinet that integrates AC incoming distribution, AC load output and DC operating power supply into a single cabinet body. It is widely used in small and medium-sized substations, industrial distribution rooms and box-type substations, providing a compact, all-in-one power solution for both power equipment and control systems.
The panel is usually divided into upper and lower functional compartments. The AC compartment introduces mains or generator power, and distributes power to AC loads such as lighting, ventilation, heating and maintenance sockets through circuit breakers and surge protection devices. The DC compartment integrates rectifier modules, backup batteries and DC distribution circuits, outputting stable 110V or 220V DC for high-voltage breaker operating mechanisms, protection relays and monitoring devices.
Compared with installing separate AC distribution boxes and independent DC systems, the integrated AC/DC power supply panel has obvious advantages. It saves installation space and reduces on-site wiring work, which is especially suitable for compact box substations and small power distribution rooms with limited space. The unified structural design also simplifies later operation and maintenance, and the centralized monitoring screen allows operators to view the operating status of both AC and DC circuits at a glance.
Most panels are equipped with complete protection functions including overcurrent, short circuit, overvoltage and undervoltage protection. Premium models also support remote communication and fault alarm, which can be connected to the upper monitoring system to realize unattended operation.
When selecting a model, users need to confirm the AC incoming voltage, the number and capacity of AC output circuits, the DC rated voltage and current, and the backup battery capacity. Wall-mounted panels are suitable for small stations with low capacity requirements, while floor-standing cabinets are recommended for medium-capacity scenarios that require more output circuits and longer backup time.
