Iota IQ4 FACTORY- INSTALLED for DLS Series

The IQ4 Controller allows the DLS charger to operate as an automatic 3-stage "smart charger". This gives the customer the benefit of Bulk, Absorption, and Float stage charging, increasing the charging capacity of the DLS charger and decreasing charge times, insuring proper and safe battery charging and minimizing over-charging. This "smart" technology monitors the battery at all times. If the DLS voltage remains in the long term float stage for more than 7 days, the IQ will automatically deliver a boost charge for a predetermined time, then automatically return to the normal float stage.

DLS power converters can be ordered with the IQ Controller option internally integrated into the unit.

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 12V systems) for increased capacity.

Float Charge
During the float stage, the DLS charge voltage is reduced. This minimizes gassing, while maintaining a full charge. If the battery voltage drops below 12.6vdc (for 12V systems), the IQ Controller 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 IQ Controller 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.
