This advanced three-stage, 50-amp battery charger is a cost-efficient way to automatically charge 12V deep cycle lead acid batteries or power a 12VDC load from either a 120- or 230-volt AC source. 120VAC, 50/60 Hz input is the default, but you can change this to 230VAC 50/60 Hz input with an internal jumper setting.
A DIP switch allows you to select between a two-stage and three-stage charging algorithm depending on whether the batteries to be charged are connected to a DC load. The SEC-1250UL battery charger is compatible with all varieties of 12V lead acid batteries (flooded, AGM, and gel cell) and can charge up to three separate battery banks at once with no isolator needed.
Featuring overload and short-circuit protection, the Samlex SEC-1250UL can also be used as a DC power supply for 12VDC loads.
