The IQ4-54V Smart Controller provides intelligent automatic charging control for your 54V DLS Battery Charger, keeping batteries fully charged and operating for long life. IQ4-54V Charge Controllers are available for any 48V DLS Battery Charger model and are backed by IOTA's Two-Year Warranty. For 4-Stage Charging, use either the external IQ4 pendant or a DLS charger with built-in IQ4 control.

The IQ4-54V 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 48V charger will charge at a maximum of 59.2V). 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 (56.8V for a 48V battery system). 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.
