The GZDW series DC power supply panels adopt cadmium-nickel storage batteries and floating charge generators, and are equipped with automatic detection and alarm devices. They feature a long service life, no pollution, easy maintenance, stable voltage, ultra-low internal resistance output, strong resistance to large current surges, high adaptability and reliability.

These DC power supply panels are ideal DC operating power supply devices, which can be widely used in substations with a voltage of 500 kV and below, and power plants with a single-unit capacity of 200,000 kV and below. They are also applicable in sectors such as metallurgy, mining, petrochemicals, radio and television, computer rooms, subways, and high-rise buildings, serving as DC control power, signal power, power-off protection, and the opening and closing current for the circuit breaker operating mechanism
