Reintroducing the ADUW Hard-wire, High-Power Step Up/Step Down Voltage Transformers

ACUPWR has reintroduced our ADUW hard-wire, knockout box voltage transformers/converters. These step up/step down models—110-120 to 220-240 volt, and vice-versa—are hard-wire types that connect directly to an electrical junction box and the actual appliance. For that reason, the ADUWs do not have plugs and receptacles.

As a step up transformer, the ADUW will convert power from the 110-120 volt standard used in the USA and Canada up to 220-240 volts. This will satisfy the high power (220-240 volts) demands of appliances such as cook tops, wall ovens, ranges, clothes dryers, and steam generators. When operating in its step down mode, the ADUWs will convert any hard-wireable 220-240 volt appliance down to 110-120 volts for use in the USA and Canada. A switch easily converts voltage modes.

The ADUW models are knockout models; they look like other ACUPWR transformers except for one side having a knockout hole that accepts AC input and output wiring.

We particularly recommend the ADUW models for use with such products as Bosch 500 series, Bertazzoni Professional Series, and Viking Pro Series cook tops, and Wolf range/wall oven/stove models. They’re available in 500-, 1000-, and 1500-watt models (the ADUW-500, ADUW-1000, and ADUW-1500 respectively).

Note: ACUPWR recommends that the ADUW and other hard-wire models be installed by a qualified and licensed electrician.
