As a power supply, the unit's tightly controlled regulation allows the user to operate a nominal 12VDC load up to 55 amps.
As a battery charger, the unit will maintain the battery, delivering its full-rated current when the battery capacity falls sufficiently low. The voltage is set to deliver its maximum current for the necessary period of time to minimize undue stress to the battery caused by heating of its cells. This helps to ensure the longest possible life of the battery. Over time, as the battery nears its full capacity, the DLS-55 will automatically drop the current, providing a float-charge to the battery to prevent self-discharge of the cells.
