Samlex 15A 12V 3-Bank 3-Stage Battery Charger

The Samlex 15A Battery Charger is a fully automatic three-stage charger built for all types of 12 Volt lead-acid batteries, including Flooded, Absorbed Glass Mat (AGM), and Gel Cell. It runs off either a 120 VAC 60 Hz or 230 VAC 50 Hz source and can charge up to 3 separate battery banks simultaneously without an isolator.

A DIP switch allows conversion to a two-stage algorithm for batteries connected to a DC load, and the unit can also serve as a standalone DC power supply. A voltmeter, ammeter, and LED power status display support monitoring, while the Universal Protection Circuit guards against short circuit, overload, and reverse battery polarity.
