Samlex 25A 24V 2-Bank 3-Stage Battery Charger

The Samlex 25A Battery Charger is a fully automatic three-stage charger built for all types of 24 Volt lead-acid batteries, including Flooded, Absorbed Glass Mat (AGM), and Gel Cell. It runs off either a 120 VAC or 230 VAC source at 50/60 Hz and can charge up to 2 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. Built-in voltmeter and ammeter monitoring, fan cooling, and protection against overload, short-circuit, reverse polarity, and thermal overload keep charging safe, and the included temperature sensor prevents under or overcharging as conditions vary.

Frequently Asked Questions

Can this charge two battery banks at once? Yes, it can charge up to 2 separate battery banks simultaneously without needing an isolator.

What does the DIP switch control? The DIP switch selects between 2-stage and 3-stage charging and allows configuration of the AC input voltage between 120 and 230 VAC.

How does this compare to the 12V 50A model? This charger (SEC-2425UL) outputs 25A at 24V, while the 50A version (SEC-1250UL) outputs 50A at 12V; both share the same features and protections.
