75 amp IOTA DLS Series AC-to-DC converter and battery charger for 12V RV battery systems. The built-in IQ4 smart charging module provides automatic 4-stage charging for battery charging, maintenance, and stable high-current DC power supply operation.
The IOTA 274ETS DLS-75/IQ4 is a 75 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 lights, fans, pumps, control boards, and other DC loads while also charging the RV battery bank.
With the built-in IQ4 smart charging controller, the DLS-75/IQ4 automatically manages battery charging through bulk, absorption, float, and maintenance charging stages. This makes it a strong choice for higher-demand RV electrical systems that need more charging output than a 30A, 45A, or 55A converter can provide.
Provides up to 75 amps of regulated 12V DC output for charging and DC loads
Integrated IQ4 controller adds automatic 4-stage battery charging
Useful for larger RV, trailer, coach, and mobile 12V DC power systems
Includes short circuit, reverse polarity, overload, and thermal protection
The DLS-75/IQ4 is commonly used in larger travel trailers, fifth wheels, motorhomes, bus conversions, specialty vehicles, and mobile power systems that use a 12V battery bank and need a high-output 75 amp converter/charger. It may be used as a replacement or upgrade for compatible RV converter chargers when the AC input circuit, DC output wiring, battery chemistry, mounting space, fuse protection, and ventilation requirements are verified.
• One IOTA 274ETS DLS-75/IQ4 75 amp converter charger • Built-in IQ4 smart charging controller • AC power cord as supplied by manufacturer • Installation/operation documentation as supplied by manufacturer
This 75 amp converter should be installed in a dry, protected, well-ventilated location with properly sized AC input wiring, DC output wiring, grounding, fuse protection, and battery connections. Because 75A and larger units can draw more AC current than smaller converters, verify the RV’s AC branch circuit, receptacle/plug type, wire gauge, battery bank size, and converter compartment ventilation before installation.
Converter charger installation involves 120V AC power and high-current 12V DC wiring. Incorrect installation can cause electrical shock, fire, equipment damage, battery damage, or improper charging. Installation should be performed by a qualified RV technician or electrician familiar with RV converter/charger systems.
The IOTA 274ETS DLS-75/IQ4 is a 75 amp 12V converter charger with built-in automatic IQ4 4-stage charging for compatible RV battery systems. Verify AC input circuit, battery chemistry, wiring, fuse protection, and installation space before ordering.
