|Take your DLS Battery Charger|
to the next level...
The IQ Smart Controller offers automatic charging control for DLSBattery Chargers, providing longer and safer use of your system'sbattery. The IQ Smart Controller is compatible with any DLS BatteryCharger model and is covered under our standard Two-Year Warranty.
|TheIQ Controller allows the the DLS Charger to operate as an automatic3-stage "smart charger." This gives the customer the benefit of Bulk,Absorption, and Float stage charging, increasing the charging capacityof the DLS charger and decreasing charge times, insuring proper andsafe battery charging and minimizing over-charging. This "smart"technology monitors the battery at all times. If the DLS voltageremains in the long term stage for more than seven days, the IQ willautomatically deliver a boost charge for a predetermined time, thenautomatically return to the normal float stage.|
Reduced Charge Times
The Bulk Stage allows the batteries to be charged from the full rated output of the DLS charger. During this stage the batteries are recharged quickly to reduce charge times
|Increased Battery Capacity|
After the Bulk Stage, the batteries are held in the Absorption Stagefor a controlled period, insuring a full and complete charge.
|Reduced Battery Stress|
During the Float Stage, the DLS charge voltage is reduced. Thisminimizes gassing while maintaining a full charge at the nominal rateof the battery.
|Weekly Equalization for Longer Battery Life|
If the batteries have not received a "smart charge" during a seven-dayperiod, the IQ Controller will switch the DLS charger into apre-programmed equalization stage to top off the batteries, dissolvingany sulfate layer on the battery's internal plates and avoidingstratification.
The LED Indicator on the IQ4 informs the user as to the status of thebattery and the charging stage. When first activated, the IQ4 will readthe number of cells in the battery and indicate the voltage of thebattery through a number of flashes.
6 flashes = 12 volt battery
12 flashes = 24 volt battery
18 flashes = 36 volt battery
24 flashes = 48 volt battery
After reading the battery, the IQ4 will initiate either a Bulk Chargephase or Float Charge phase depending on the battery's charge status.When the IQ4 is in the Bulk Charge mode, the green LED indicator willflash rapidly. When the Bulk Charge is complete, the IQ4 begins theAbsorption Charge and the LED indicator will flash at a slower rate.When the battery charging is complete and the IQ4 begins the FloatCharge, the LED will remain lit and no longer flash. If, when firstactivated, the battery is not in need of charging, the IQ4 willimmediately begin the Float charge phase and the LED will be remain litafter it has counted the battery cells.
The charging voltages used to charge the battery during the threestages differ depending on the voltage of the battery being charged. Ifyou are interested in knowing the various voltages, they are easy tocalculate. Follow the simple steps below:
1) Determine the number of cells your battery has by counting the flashes on the IQ4 when it is first activated (1 flash = 1 cell)
2) Multiply the number of cells by the appropriate voltage for the individual charging stage. Use the table below for reference:
|Charging Phase||Voltage Charge per Cell|
Example: A 12V battery (6 cells) will Bulk Charge at 14.76V (6 x 2.46).
|EXTERNAL IQ DIMENSIONS|
|Most DLS Models are available with the IQ Smart Charger already internally integrated within the unit. External IQ models can be installed by simply plugging the IQ cord into the Dual Voltage jack located on the top of the DLS Models. The IQ circuitry is then automatically engaged. .|
