Description The IQ4 Charge Controller allows the DLS Series battery charger to operate as an automatic 4-Stage "Smart Charger," delivering the charge your battery needs at the time it needs it. The IQ4 uses four different charging modes to keep your battery in peak condition...
BULK STAGE The Bulk Stage of the IQ4 allows the batteries to be charged from the full rated output of the charger (for example, a 12V charger will charge at a maximum of 14.8V). This increased charging period reduces the overall charging time of the battery.
ABSORPTION STAGE After the Bulk Stage, the IQ4 then moves to the Absorption Stage (14.2V for a 12V battery). This mode will continue for up to 480 minutes (8 hours) to ensure that the battery receives a complete charge.
FLOAT STAGE During the Float Stage, the IQ4 reduces the DLS charge voltage. This reduced voltage maintains the full charge while minimizing 'gassing' of the battery. The IQ4's float stage prevents boiling and bulging of the battery caused when the battery is exposed to higher charging voltages for too long.
EQUALIZATION STAGE If the batteries remain in a "float stage" for a seven-day period, the IQ4 will switch the DLS charger into a pre-programmed Equalization Stage. This protects the life of your battery by dissolving any sulfate layer on the battery's internal plates and avoids stratification that can occur when a battery has not been in use for extended periods.
IQ4 Standard IQ Smart Charging pendant upgrades any 12V or 24V DLS battery charger to an automatic 4-stage charger.
54V IQ4 Modified for optimal performance with any 54V DLS battery charger.
IQ4 Parallel Includes specialized cord for 4-stage charging control of two 12V or 24V DLS chargers operating in parallel.
Installation The IQ4 can be easily installed by plugging the IQ4 cord into the Dual Voltage jack located on the DLS*. The IQ circuitry is then automatically engaged. NOTE: The cord provided with the IQ4 is only designed for use with the charge controller. Do not use the IQ4 with any cord other than one that is supplied with the unit.
If you are using an IOTA DLS Battery Charger that does not feature a Dual Voltage Jack, you can still attach an IQ4 Smart Charge Controller to your system
