The IQ4 Controller auto-configures to 12, 24 or 48 volt configurations. It allows the DLS charger to operate as an automatic 4-stage "smart charger". This gives you the benefit of Bulk, Absorption, and Float stage charging, increasing the charging capacity of the DLS charger and decreasing charge times, insuring proper and safe battery charging and minimizing over-charging. This "smart" technology monitors the battery at all times. If the DLS voltage remains in the long term float stage for more than 7 days, the IQ4 will automatically deliver a boost charge for a predetermined time (180 minutes), then automatically return to the normal float stage. All DLS converters are compatible with IQ4 Smart Control Technology. The IQ4 Smart Charger allows a DLS charger to operate as an automatic (Bulk, Absorption, and Float) smart charger plus a weekly equalization function. The IQ4 Smart Charger installs simply by plugging into the DLS Dual Voltage Jack. The Smart Charge circuitry is automatically engaged.

I fell in love with your company when I was on the phone with Tom. I had this large quote and he started telling me all the things I could do to cut the cost.
Hooray! you guys are great, and I plan to buy more stuff from you in the future when I upgrade some things.
It is so nice to find pleasant people to do business with and you folks are very pleasant, thank you!
Wow! I have never spoken with anyone who knows about this stuff like you and I have never spoken with anyone who could explain it to me so that I could understand it too!
Keep In Touch!
We will never sell or share your information to anyone
