    40A Battery Guard

    The universal programmable Battery Guard (BG) prevents the excessive discharge of the battery (which would damage the battery) and protects electronic appliances against overvoltage. The BG40 battery guard has an “Automatic Board System Detection”; the BG automatically detects the battery voltage (12 or 24V). The BG40 battery guard is capable of carrying 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.
