BGW-40 Waterproof Battery Guard - 40 AmpsThe Battery Guard Waterproof BGW-40 is an intelligent, user-programmable, fully waterproof battery guard. The battery guard prevents the excessive discharge of the battery (which would damage the battery) and protects electronic appliances against overvoltage. Includes “Automatic Board System Detection,” the BG automatically detects the battery voltage (12 or 24V). The BGW-40 battery guard is capable of carrying a 40A continuous load and 45A 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 has additional options for a remote off switch and an alarm output for connecting a buzzer, LED strip, or relay.Features:Can be set to connect/disconnect at several different voltages with jumpersHelps batteries last longerPrevents damage to connected componentsPrevents excessive voltage caused by faulty alternators or chargersFully waterproofApplications:Marine, automotive, and recreationalSpecifications:Input: 6-35 VDCOutput: 6-35 VDCAmps: 40 AmpsWeight: (lbs) 0.4 / (kg) 0.2Dimensions: (inch) 2.44" x 2.83" x 1.26" / (mm) 62 x 72 x 32 *No battery included
