Bigger appliances such as ranges, cook tops, grills, and steam machines typically require 220-240 volts and 30/60 amps of power. ACUPWR’s ADUW-1500 step up/step down voltage transformer is ideal for this purpose. It’s a 1500-watt knock-out box/hard-wire model that wires directly to the appliance or a junction box, and therefore doesn’t have a plug and receptacle. As a step-down unit, is allows overseas models that run on 220-240 volts to operate in the USA and Canada (where the voltage standard is 110-120 volts). 

The ADUW models, like all ACUPWR products, are manufactured in the USA with the best materials available, including copper wiring and silicon steel. They’ll work perfectly under duress and in heavy-duty situations. Moreover, unlike less expensive, foreign-made products using aluminum wiring, our products are designed to last for decades. Each unit is hand assembled in our factory and bench-tested beyond rated wattage to ensure years of dependability. Among the ADUW’s features is thermal protection; the unit will turn off when overheated.

ACUPWR stands by its products by providing a lifetime warranty. We count military and government agencies, including NASA’s Goddard Space Flight Center, among our customers for good reason: ACUPWR products are the best-made, most dependable, and most long-lasting transformers available.

When considering which model ACUPWR transformer/voltage converter is best for your needs, keep in mind that our products are safe for continuous power at 120 percent beyond the stated wattage, unlike other products that adhere to an industry standard of 1.5 times the appliance’s stated wattage. So, for example, an appliance rated for 300 watts of consumption would, according to the industry standard, require a 450-watt transformer. With an ACUPWR transformer, you can safely use your 300-watt appliance with a 300-watt transformer/converter; our products, remember, it can handle 120-percent beyond their stated wattage handling ability.

The ADUW-1500 comes with a lifetime warranty.
