Industrial SEC-2425UL Automatic Battery Charger

The Samlex SEC-2425UL is a 24-volt, 25-amp automatic battery charger designed to safely recharge all types of 24‑V lead‑acid batteries, including flooded, AGM, and gel cells, from either 120 VAC at 60 Hz or 230 VAC at 50 Hz. This safety-listed, fully automatic charger delivers three‑stage charging (with a DIP switch to select two‑ or three‑stage operation) and includes a Half Power Mode for smaller batteries. It can charge two separate battery banks simultaneously and can also function as a DC power supply when connected to a battery, making it versatile for both charging and providing auxiliary power. Protection features encompass overload, short‑circuit, reverse polarity, and thermal overload protection, helping prevent damage to both the charger and connected batteries. A battery temperature sensor is included to enable temperature‑compensated charging for optimal performance across temperatures.
