The power supply security device for railway crossing equipment includes F type, FN type and other products, which combine AC power supply and DC power supply security device. Ac power supply in recent years The way of protection with lightning-resistant transformers has become mainstream, and the security device for AC power is no longer needed, so the structure is simplified to only the DC power part. And because The DC power supply part is also separated into external and internal lines, the wiring separation operation is more simplified, if you want to increase the internal power capacity of the appliance box, as long as the internal line is added FMBM type security device is available.
