Programmable Battery Guard is the ideal solution for operators and installers, when batteries need to be protected from heavy discharge due to additional loads being fitted. The Battery Guard is a Microprocessor controlled battery guard. The unit has four faston connections, 2 input and 2 output connections to guarantee low losses. A yellow LED shows the status. In programme mode it shows the programme position. The BG has an 'Automatic Boardsystem detection'; detecting which battery voltage(12 or 24) is used. This does not need to be programmed manually. There is a choice of 10 on/off threshold voltage programmes, for both 12 and 24 V, which can be programmed in a simple way. The BG uses very little current. During overvoltage the BG uses just 2mA or less.
