This advanced three-stage, 40-amp battery charger is a cost-efficient way to automatically charge 24V deep cycle lead acid batteries or power a 24VDC 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-2440UL battery charger is compatible with all varieties of 24V lead acid batteries (flooded, AGM, and gel cell) and can charge up to two separate battery banks at once with no isolator needed.
Featuring overload and short-circuit protection, the Samlex SEC-2440UL can also be used as a DC power supply for 24VDC loads.
