Description

GZDZ series cadmium nickel battery DC screen is an upgraded product, suitable for use in power system of small power plants, substations, industrial and mining enterprises, control rooms, as the switching battery of high-end circuit breaker DC operating system, and also plays the role of control circuit, relay protection, signal circuit and accident light.

Product Features:
1. With three-phase full control bridge collator instead of hammer saturation type main filling and floating machine in traditional products, it overcame the traditional shortcomings of low voltage accuracy, low current accuracy, loud noise and high temperature rise.
2. Use non-contact switch input as the Alternate channel transferring way.
3. This series DC screen adopts the best charging way for battery, prior constant current and later constant pressure, and can realize automatic conversion in charging status.
4. This series DC screen has functions of automatic current stabilizing, automatic voltage stabilizing, current-limiting, short circuit protection and overvoltage protection.
5. The machine can output signal contacts of bus voltage high or low, bus grounding, charger fault, etc.
