Samlex 30A 12V 3-Bank 3-Stage Battery Charger

The Samlex 30A 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.

Frequently Asked Questions

Can this charge multiple battery banks at once? Yes, it can charge up to 3 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 50A 2-bank model? This charger (SEC-1230UL) outputs 30A across 3 banks, while the SEC-1250UL outputs 50A across 2 banks; both charge 12V lead-acid batteries with the same voltage/frequency flexibility.
