Iota Charge ControllerThe IOTA IQ4 Smart Charge Controller provides automatic bulk, absorption, float and equalization charging control for IOTA DLS Series battery chargers. The four-stag charging process reduces charge times, ensures a complete and constant charge, and prolongs battery life by preventing stratification and sulfate accumulation that occurs while the battery is not in use. The IQ4 is easily installed by plugging directly into the voltage jack on the DLS charger, automatically activating the IQ charge control circuitry. For use with any 12V or 24V DLS Series battery charger of any amperages. Includes 10" cord. 2.6" x 1.3" x .7". Includes 2-year warranty.Features:Provides Intelligent Automatic Charging Control For Your DLS Battery ChargerAllows The DLS Series Battery Charger To Operate As An Automatic 4-Stage "Smart ChargerBulk Stage Allows The Batteries To Be Charged From The Full Rated Output Of The ChargerHelps Prevent Gassing, Boiling, And Bulging Of BatteriesProtects Batteries From Stratification And From Sulfating Of Battery PlatesFlashing LED To Indicate Current Charging StageEasy InstallationLimited 2 Year WarrantyCompatibility: DLS Series Battery ChargersVoltage Rating: 12 To 48 VoltDisplay Type: No DisplayWith LED Indicator: YesCharging 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.
