40 HP Phase Converter

The 40 hp/40 kVA 3 phase converter from American Rotary is designed to power most loads up to 20 hp or 56 amps.

The AD40 is the perfect solution for voltage-sensitive equipment such as welders, ovens, EDMs, and CNCs. It was designed with our microsmart controller to give you more precise power and efficiency.

Benefits of the AD40 include reliability, precision, and longevity.

The ADX40 is our most versatile series designed to give you the cleanest, most balanced power for high inertia loads such as pumps, air compressors, and equipment with a flywheel, yet it is able to handle the most sensitive type of loads. Advantages to the ADX40 include our CTR Technology which allows for on-demand call of power for the toughest starting loads. Making the ADX40 the best choice for all consumers.

The AUL40 offers the same great technology as the ADX40, but it comes with a UL registration needed in certain applications. Ask your electrician if UL registration is required in your installation.

The AI40 takes the precision and power of the ADX40 and packs it into a fully enclosed NEMA 3R-rated enclosure. Advantages to the AI40 include a lifetime wash down filter, solar reflective paint, and a 3R weatherproof enclosure allowing you to put the AI40 outdoors or indoors. So whether it is dust or the outside elements you are looking to protect your equipment from, you will benefit from the AI40 phase converter.

Rest assured that whichever American Rotary model you choose, it will give you many years of reliable power and is backed by its lifetime warranty.

The AR, AD, ADX, and AUL models are available in floor mount and wall mount configurations. Some assembly required.
