Samlex 50A 12V 2-Bank 3-Stage Battery Charger

The Samlex SEC-series is a 50A 12V two-bank three-stage charger, UL-1564 listed, working as a battery charger, regulated DC power supply or part of a DC UPS.

Doing three jobs is what distinguishes this from a plain marine charger. As a regulated DC supply it can run equipment directly, and in a UPS role it keeps DC loads alive through a power failure. That suits communications gear, monitoring equipment and any installation where the load has to keep running rather than simply being recharged afterward.

Switch-mode design makes it lighter, quieter and more efficient than a transformer-based charger of the same output, which matters at 50 amps where a transformer unit is very heavy indeed. Three-stage charging is standard with a two-stage mode selectable, and it supports flooded, AGM and gel batteries.

UL-1564 listing is the safety standard for battery chargers, and it is worth having on equipment left running unattended. Fifty amps across two banks is substantial output, suiting boats, recreational vehicles and fixed backup installations alike. Explore more 2-bank battery chargers.
