The Battery Voltage Protector BGW-400 is an intelligent, user programmable, fully waterproof low voltage disconnect. The battery voltage protector prevents excessive discharge of the battery (which would damage the battery) and protects electronic appliances against overvoltage. The BGW automatically detects the battery voltage (12 or 24V). The battery voltage protector is capable of carrying 400A continuous load and 410A transient load. There is a choice out of 10 on/off threshold voltage programs, for both 12V and 24V battery systems, which can be easily programmed. The BGW-400 has additional options for a remote off switch and an alarm output for connecting a buzzer, LED strip or relay. With its new rubberized polyurethane construction and low profile design, the battery voltage protector can be easily mounted in any location. Input: 6-35 VDC. Output: 6-35 VDC. Amps: 400 Amps. Weight: 2.2 lb. Dimensions: 2.1" X 8.1" X 3.45".
