The IOTA DLS-54-13 is a solid-state, high-efficiency battery charger and AC power converter. It converts nominal 120-volt AC power to 54.4 volts DC for charging 48V deep cycle batteries.
As a battery charger, the DLS-54-13 will maintain the battery, delivering its full-rated current when the battery voltage falls sufficiently low. During the recharge phase, as the battery nears its full capacity, the DLS-54-13 will automatically taper the current to achieve constant voltage. An RJ11 telephone-style jumper plug (included) selects between the upper and lower voltage setpoints.
