Low Voltage Disconnect | Marine Toggle Switch Panels, Fuses, Circuit Breakers Manufacturer | YIS Marine
Rear insulating cover helps protect rear terminalsBF455 is designed to protect batteries from excessive discharge by automatically disconnecting non-essential loads when battery voltage drops below the preset level. It is an ideal battery protection solution for single-battery boats, vehicles, caravans, RVs, and other DC power systems where maintaining enough battery power for engine starting or essential equipment is critical.
BF454 is designed to manage charging between two battery banks, and BF455 focuses on load protection. When the battery voltage becomes too low, the unit disconnects the connected load to help preserve battery capacity. Once the battery voltage recovers, the unit automatically reconnects the circuit. With a compact and durable design, BF455 is suitable for harsh marine and vehicle environments. The waterproof housing, robust terminal design, and flexible mounting options make it easy to integrate into new or existing DC power systems. YIS Marine is a high-quality marines and boats Low Voltage Disconnect, Low Voltage Disconnect (LVD)-BF455 manufacturer from Taiwan, China since 1992. YIS Marine is a professional manufacturer devoted to providing high quality marine electrical and electronics products. By designing and manufacturing in-house and having quality control at Taiwan headquarter, we are able to offer high quality marine products at competitive prices.
