The GZDW series DC screen is equipped with cadmium nickel batteries, float charging motors, and automatic detection and alarm devices. It has the characteristics of long service life, no pollution, easy maintenance, stable voltage, ultra-low internal resistance output, strong adaptability to high current impact, and high reliability. It is an ideal DC operation power supply device that can be widely used in substations and power plants below 500KV, as well as in metallurgy, mining, petroleum, broadcasting and television, computer rooms, underground railways, high-rise buildings and other departments. It can be used as a DC control, signal power supply, power-off protection and circuit breaker operation mechanism opening and closing power supply.

This product complies with the standard JB/T5777.4-2000 "General Technical Conditions and Safety Requirements for DC Power Supply Equipment in Power Systems".
