Maglev【Auxiliary filter】

The charger drives all DC24V DC load and meets the charging requirements of the battery. The battery can be floating charged according to the charging characteristics of the battery. The battery box has the temperature compensation control function.When the train has no network pressure, the capacity of the battery should be able to supply the internal emergency lighting, external lighting, emergency ventilation, on-board safety equipment, broadcasting, partial display, communication system for 30 minutes, and the train should be switched once and the auxiliary power supply can be started when the network pressure is restored.
