    ACUPWR’s AUD model is a grounded step up/step down transformer that will convert voltage from 110-120 volts to 220-240 volts, and from 220-240 volts to 110-120 volts at the flick of a switch. It's suitable for home, commercial, and industrial applications. Compatible appliances include ceiling fans, security systems, home theater systems, garage door openers, desktop computers and much more (please refer to our transformer guide). This model comes with a Schuko (type F) wall plug and a NEMA 5-15R grounded receptacle for up to 15 amps output.

    As with all ACUPWR products, the AUD models are proudly manufactured in the USA using the best materials available. This includes copper wiring that allows the AUD-500 to operate under heavy duress, and in the most heavy-duty situations. 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 at a full-load (the maximum stated wattage) to ensure years of dependability. Among the AUD-500 features is thermal protection; the unit will turn off when overheated.

    ACUPWR stands by its products by providing a lifetime warranty and insurance coverage up to $10,000. 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 20 percent beyond the stated wattage in the event of an emergency. Further, ACUPWR transformers are 100-percent safe at their stated wattage , unlike other models on the market that require you to buy twice as much wattage as necessary--otherwise, their transformers will likely break down if you approach their stated wattage. 

    ACUPWR recommends that you purchase our Global Surge Protector to protect your appliances from voltage spikes. Additionally, our Global Surge Protector allows you to plug in up to 6 appliances using any plug type, thus ensuring its use anywhere in the world. We also highly recommend our voltage stabilizers/line conditioners, in countries where the line voltage is particularly unstable.
