Iota Charge Controller

Charging Phase Voltage Charge per Cell:
Bulk Charge 2.46
Absorption Charge 2.36
Float Charge 2.26

Bulk Charge
The batteries are charged from the full rated output of the DLS charger. During this stage, the batteries are recharged quickly to reduce charge times.

Absorption Charge
The batteries are then held in the absorption stage for a controlled period, insuring a full and complete charge. During this stage, the battery cells are equalized to 14.2vdc for increased capacity.

Float Charge
During the float stage, the DLS charge voltage is reduced to 13.6vdc. This minimizes gassing, while maintaining a full charge. If the battery voltage drops below 12.6vdc, the IQ4 will restart at the bulk charge stage and repeat this cycle.

Weekly Equalization
If the batteries have not received a "smart charge" during a 7 day period, the IQ4 will switch the DLS charger into a pre-programmed, equalization stage to top off the batteries. This ensures full batteries all of the time without over-charging. IQ4 Controllers feature an installation jack plug. Simply plug the IQ4 Smart Controller into the Dual Voltage Jack on the top of the DLS unit. The smart-charge circuitry is then automatically engaged.
