Analytic Systems BCD300-32-24
The BCD300 battery charger outputs up to 300 watts to charge a 12V or 24V battery system (1 or 2 banks) from any higher voltage between 20 and 45 volts. The source and the batteries under charge must share a common ground. Multiple stages of filtering reduce radiated or conducted noise to very low levels.
The two stage charging profile charges the batteries at a constant current until the battery voltage reaches the float voltage that the unit is set to and then the current into the batteries will taper off as necessary to maintain the batteries at the float voltage.
The unit 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 lead-acid battery including lead acid and gel cell.
