The Samlex SEC-1280UL is an advanced fully automatic three-stage 80 Amp marine battery charger. It is ideal for charging all types of 12 Volt lead-acid batteries ( Flooded / Absorbed Glass Mat (AGM) / Gel Cell) from a 120 V, 60 Hz or 230 V, 50 Hz AC source. By means of a DIP switch setting, conversion to a two-stage algorithm is possible to charge batteries connected to a DC load (DC UPS). The unit can also be used as a DC Power Supply. Features include overload, short-circuit and over-temperature protection. This automatic smart charger allows charging of up-to 2 separate battery banks.

Great product at a premium price
Have 12 of these units powering amateur radio repeaters. They last about 10 years then fail to put out proper voltage. Bought 2 units for spares. Best price from this seller. Would use a cheaper unit but the temperature sense is a must.
