The SA3000 additional bus power supply is a unit that, when properly housed in the plastic box or metal box, which can be purchased separately, makes it possible to increase the availability of power and the amount of devices connected to the MP3000 control panel. The board has 2 output buses and an additional power supply output, which can be galvanically separated from the central unit power supply by jumper JP2. The power supply is connected via BUS to the central unit from which it is supervised. It is possible to connect 7Ah batteries in a plastic box or 18Ah batteries in a metal box; jumper JP3 allows appropriate selection of charging current for 7Ah or 18Ah batteries.
