55 amp IOTA DLS Series AC-to-DC converter and battery charger for 12V RV battery systems. Compatible with the optional IQ4 smart charging controller for automatic multi-stage charging and improved battery charging and maintenance.
The IOTA DLS-55 is a 55 amp converter charger that converts 120V AC shore power or generator power into regulated 12V DC output for RV battery charging and DC load operation. It can power compatible 12V DC loads while also maintaining the RV battery bank.
When used with a compatible IQ4 smart charging controller, the charger automatically manages charging through multiple stages instead of holding a single fixed voltage. This helps bring batteries up to charge, reduce overcharging risk, and maintain the battery bank during storage or extended hookup. The IQ4 controller is sold separately and is not included with this converter.
Provides up to 55 amps of regulated 12V DC output for charging and DC loads
Supports automatic multi-stage charging when used with an optional IQ4 controller
Useful for RV, camper, trailer, and mobile 12V DC power systems

The DLS-55 is commonly used in travel trailers, fifth wheels, motorhomes, truck campers, cargo conversions, and off-grid mobile power systems that use a 12V battery bank and need a 55 amp converter/charger. It may be used as a replacement for compatible RV converter chargers when the AC input, DC output rating, wiring, battery chemistry, mounting space, and ventilation requirements are verified.
