Iota IQ4-X Specification Sheet

IOTA’s IQ4-X Smart-Charging Technology enables any DLS-X Series

charger to automatically deliver the advantages of Bulk, Absorption,

Float, and Equalization stage charging, resulting in fast, safe charging

of system batteries and protection against sulfation and stratiﬁcation for

optimal battery life.

SMART CHARGING BENEFITS

The Bulk Stage allows the DLS unit to charge batteries at its full-rated output

for a predetermined duration, reducing the time needed to charge the battery.

Absorption

During the Absorption Stage, the voltage drops and the batteries are then

held for a controlled period at a voltage slightly less than the Bulk voltage to

ensure a full and complete charge.

Float

At the Float Stage, the DLS unit delivers a ‘trickle’ charge, maintaining the

battery’s full charge while avoiding the dangers of “gassing” or “boiling” caused

by over-charging.

IQ FUNCTIONS

Rev. 060617

Automatic, worry-free maintenance

of system batteries.

Delivers a full charge quickly without risk of

boiling or increased gassing of the battery.

Optimizes battery life by preventing dam-

aging stratification and sulfation.

On-board docking of the IQ4-X module al-

lows for easy installation on DLS-X models

without additional mounting.

Equalization

If the battery remains in the ‘Float’ state for an extended period, the IQ4-X

charge controller re-initializes the smart-charge cycle to dissolve any sulfate

layers accumulated on the battery plates and to prevent stratiﬁcation.

The external IQ4-X module connects to the module docking port on

the end of the DLS-X unit. Simply remove the screw securing the

port cover, and insert the IQ4-X module. The IQ4-X flanges will snap

into place and the IQ4-X will automatically initiate the smart-charging

circuitry. Re-attach the screw to secure the IQ4-X onto the DLS-X.

LED indicator light provides a visual indication

of the current charging stage of the IQ4-X.

OPERATION The LED Indicator on the IQ4-X informs the user of the DLS-X charging state and the battery charge status. When first activated, the IQ4-X will read the number of cells in the battery and indicate the voltage of the battery through a number of flashes. Refer to Figure A Figure A: LED Code Table LIT/FLASHING LED - After reading the battery, the IQ4-X will initiate in Bulk Charge phase. When the IQ4-X is in the Bulk Charge mode, the green LED indicator will flash rapidly (approx.
