IQ-4 Smart Chargers
For DLS Charge Controllers

Already own an Iota DLS Charge Controller? Use these IQ Smart Controllers to turn it into a "smart charger"!

IOTA IQ Smart Charge Controllers are plug-and-play charge control modules that plug right into your IOTA DLS Charger to deliver automatic enhanced performance, overall faster charging, and better maintenance for optimal battery life.  Simply plug the IQ Smart Controller into the Dual Voltage Jack on the top of the DLS unit. The smart-charge circuitry is then automatically engaged. 

IQSmart Controllers offer automatic charging control for the DLS power converters/chargers to provide longer and safer use of your system's battery. All of the controllers can charge a battery from zero.  The IQ Controller is compatible with any DLS model, and is covered under IOTA's standard Two-Year Warranty.

Here are the different models:

• IQ4: The traditional IQ4 Smart Charge Controller delivers 4 basic charging functions: BULK, ABSORPTION, and FLOAT, and a seven-day MAINTENANCE cycle. The IQ4 is an excellent way to maintain your stored flooded lead acid batteries, such as in an RV that is parked for extended periods of time. (**Factory installed, 54V, and Parallel Charging options also available).
• IQ-TURBO: The IQ-Turbo delivers a powerful yet controlled voltage to help charge batteries in minimal time. Perfect for batteries that are used frequently but with limited time for re-charge, such as when connected to a generator or solar panel system.  The Turbo offers rapid charging for continually-cycled batteries, and can charge from zero the fastest.
• IQ-EQUALIZER: The IQ-Equalizer is a useful charge control tool that initiates a constant current BULK charge to your flooded lead acid battery, ensuring that all cells receive an adequate, complete charge in an abbreviated timespan. After a predetermined period, the IQ-Equalizer drops into a trickle charge until re-inserted for additional equalization.
• IQ-LIFEPO: The IQ-LIFEPO is tailored for use with today’s state-of-the-art LiFePO4 batteries that use a Battery Management System (BMS). The IQ-LIFEPO allows the DLS to deliver proper voltage to charge the larger 4-cell design of the battery and remains in a stand-by trickle mode ready to deliver a fresh BULK charge when needed.
• IQ4-GEL: The IQ-GEL features an extended BULK stage but with a slightly decreased voltage that is just right for Gel lead-acid batteries. After a period of seven days, the IQ-GEL will initiate the standard Maintenance cycle to ensure the battery remains in peak charged status.
• IQ-AGM: The IQ-AGM provides tailored absorption charging for AGM (Absorbed Glass Matt) batteries by delivering an optimized BULK/FINISH stage before reverting to the FLOAT stage.
• IQ-40-HOUR: For larger systems - lead-acid battery banks with increased Amp-Hour ratings.  The IQ-40-Hour delivers an extended Bulk charge duration to service the larger capacity before reverting to standard ABSORPTION, FLOAT, and MAINTENANCE modes.

NOTE: External IQ Smart Chargers are NOT compatible with DLS with internal IQ charge control. Also, current models are are only designed for 12V and 24V DC applications.
