IOTA Battery Charger - 24V, 40A (DLS-27-40) 

The IOTA DLS-27-40 Battery Charger is a solid-state, high-efficiency battery charger and DC power source. It converts 120 nominal (108 – 132) volts AC to 27.2 or 28.4 volts DC for either direct load operation or 24V battery charging. 

As a power supply, its tightly controlled regulation allows you to operate a nominal 24VDC load up to 40 amps. 

As a battery charger, the DLS-27-40 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-27-40 will automatically taper the current to achieve constant voltage. An RJ11 telephone-style jumper plug (included) selects between the upper and lower voltage setpoints. Using the optional IQ4 controller, the Charger becomes a 4-stage smart charger, delivering its maximum current only for the necessary period of time to minimize overcharging and undue stress. This helps to ensure the longest possible life of the battery.
