Samlex SEC2425UL 24V 25A 2-Bank Battery Charger 3-Stage with Temperature Sensor

The Samlex SEC-2425UL is an advanced fully automatic three-stage 25 amp battery charger designed for charging all types of 24 volt lead-acid batteries including flooded, absorbed glass mat (AGM), and gel cell from a 120V 60Hz or 230V 50Hz AC source. This versatile unit can charge up to 2 separate battery banks simultaneously without requiring an isolator, and can also function as a DC power supply or DC UPS when used in conjunction with a battery.

Key Features:

• Switch mode technology delivers high efficiency, lightweight design, and quiet operation
• Automatic operation compatible with all lead-acid battery types: flooded, AGM, and gel cell
• Dual-bank charging capability charges 2 battery banks simultaneously without isolator
• User configurable AC input voltage: 120 VAC or 230 VAC, 50/60 Hz
• DIP switch selectable 2-stage or 3-stage charging algorithm for standalone or loaded batteries
• Half power mode reduces maximum charging current to 50% for safe charging of lower capacity batteries
• Built-in voltmeter and ammeter for real-time monitoring
• Temperature-controlled cooling fan activates based on output current
• Includes external temperature sensor to optimize charging and prevent under/overcharging in variable temperature environments
• Comprehensive protection: short circuit, overload, reverse polarity, and over-temperature
