MajorBCD 300 Watt DC Charger
12 VDC / 24 VDC |

MajorBCD300
The MajorBCD300 battery charger is capable of charging up to two independent banks of batteries at 12 VDC or 24 VDC. The two stage charging profile charges the batteries at a constant current equal to the maximum continuous output of the unit. When the battery voltages come up to the float voltage that the unit is set to, the current into the batteries will taper off as necessary to maintain the batteries at the float voltage.
The MajorBCD300 can be left permanently connected without fear of overcharge or damage to the batteries. The adjustable float voltage feature allows the unit to be used for any type of battery including lead acid and gel cell.

MajorBCD305
Multiple stages of filtering reduce radiated or conducted noise to very low levels. Applications include charging the compulsory battery on vessel's over 20 meters, temporarily brightening 12 volt headlights or work lights, increasing voltage into an automotive or marine ignition system for hotter spark and/or prevention of failures due to voltage drop during engine start, stabilizing 12V and 24 VDC power systems in marine, automotive or aeronautical environments and more.
