IQ4 40HOUR Smart Charge Controller

3-Stage Smart Charge Controller for the IOTA DLS Featuring Extended Bulk Charging for Larger Systems

By Iota

  • Overview
  • Specifications
For lead-acid battery banks with increased Amp-Hour ratings, the IQ4 40HOUR delivers an extended Bulk charge duration to service the larger capacity before reverting to standard ABSORPTION, FLOAT, and MAINTENANCE modes.
Installation
The IQ4 40HOUR Smart Charge Controller easily plugs into the Dual Voltage Jack of your IOTA DLS Battery Charger. Once plugged in, the IQ Smart Charge circuitry is automatically engaged and your IQ module will activate. Your DLS will now provide an automatic and trouble free charging profile to your batteries!
Note: External IOTA IQ Smart Charge Controllers are not compatible with DLS units with internal IQ charge controllers.

IQ4 40HOUR Charge States

The IQ4 40HOUR progresses through the following stages while charging your batteries:
Bulk (Extended)The Bulk Stage of the IQ4 allows the batteries to be charged from the full rated output of the charger. This increased charging period reduces the overall charging time of the battery.
FloatDuring 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.
MaintenanceIf the batteries remain in a "float stage" for a seven-day period, the IQ4 will switch the DLS charger into a pre-programmed Maintenance 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.
