The DLS Series Power Converter/Battery Charger with IQ4 Smart Charge Controller from IOTA, converts nominal 108-132 AC voltage to 13.4 DC voltage for both DC load operation and 12V battery charging. As a power supply, the unit's tightly controlled regulation allows the user to operate a nominal 12VDC load up to the unit's specified 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 converter/battery charger will automatically drop the current, providing a float-charge to the battery to prevent self-discharge of the cells.
