Samlex SEC-2440UL 24 Volt 40 Amp Battery Charger

The Samlex SEC-2440UL charger is ideal for bulk charging 24 volt battery systems (AGM, Gel, or wet) of 150 amp hour (ah) or more, or as a floating charger (long term maintenance) for batteries 100 ah or more. This unit has proportional fan cooling, mute selection for silencing the fan, and temperature compensation. They can be set for true Gel batteries, 115 VAC or 230 VAC input, or to function as a power supply. Typical applications include automotive, marine, RV, communications, military, robotics, etc. These are industrial quality, reliable units, and excellent for commercial and military applications. We have been waiting for these higher amp units for some time. This unit requires a 30 amp circuit when used at 115 VAC. Replaces SEC-2440A.

Samlex Battery Chargers

Samlex battery chargers are microprocessor controlled, fully automatic electronic devices, which use switch-mode technology to change AC input voltage to DC output voltage at much faster rates than traditional ferroresonant type chargers, which allows for a much smaller transformer, less size and weight, and increased efficiency. Samlex switch-mode chargers also will function as a power supply with a battery in the system, and the proper dip switch setting. These units are switch selectable for AC input voltage, battery type (wet, AGM, Gel), and power supply operation (battery with load). The 'battery with load' setting deactivates the boost mode, so the charger can function as a power supply without entering the elevated voltage level, which can damage a battery if applied for long periods. Proper maintenance of lead acid batteries keeps them healthy, and maximizes their life expectancy.
