All IOTA DSL units sold by Southeast Marine as battery chargers have output voltages custom set to values  which will assure proper bulk, absorption and float charging, of deeply discharged batteries. Standard IOTA factory settings are intended for power supply applications and will not properly charge batteries in any reasonable amount of time. Additionally float voltages may be improper.

The DLS Chargers feature a Two-Step Voltage Jack which allows switching from a long-term float voltage of 13.2VDC to 14.4VDC for rapid charging by simply inserting the dual voltage plug (included) into the jack. Adding an external IQ smart-controller allows automatic 3 stage charge control as well as manual equalization charging if it should become necessary. If this unit is to be used as a  battery charger and an equalization function is desired, the Iota chargers offered by some outlets with the IQ4 function built in can not be used with the equalization option as the rapid charging function is disabled. Furthermore, in applications where the primary source of charging is a generator which is only run for limited periods of time, it is best to use  the charger with out the IQ 4 option. In those cases the fastest and most complete charging is realized by utilizing the The two stage voltage jack plug in , as this will raise voltage to the higher level and maximize charging during the limited generator run period. It is up to you however to control the charge and stop charging when complete. However, If the charger is also going to be connected to shore or grid power than the IQ4 controller should be used when so connected.

Ouput currents available: 75 and 90 Amps at 12 VDC and 40 Amps at 24VDC.

The units are not ignition protected so must be mounted outside of engine spaces in gasoline powered boats to comply with ABYC and USCG requirements.

IQ4 Dual option allows two chargers to be paralelled to double charging capacity.
