The DLS power converter/battery charger from IOTA Engineering converts 108-132 AC Voltage to 54.4 DC Volt for both DC load operation and 48 Volt battery charging. To properly charge a 48 Volt lead-acid battery bank the Iota IQ4 Smart Controller has to be added, this turns the unit into a proper 4-stage charge controller.

As a power supply, the unit’s tightly controlled regulation allows the user to operate a nominal 48 VDC load up to 13 Amp.

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 will automatically drop the current, providing a float-charge to the battery to prevent self-discharge of the cells.

Dual Voltage Jack

The DLS is equipped with a dual Voltage jack and dual Voltage plug that allows manual switching from a long-term float Voltage of 54.4 VDC to 59.0 VDC. When the dual Voltage plug is inserted in the jack, the Voltage increases to 59.0 VDC for occasional fast charging. When the plug is removed, the Voltage drops to 54.4 VDC to reduce battery water loss. The dual Voltage jack also allows for easy installation of an external IQ4 Smart Controller (sold separately) for automatic 4-stage charging (optional).
