ACUPWR Global Surge Protectors and Voltage Stabilizers/Line Conditioners

It’s a known fact that many countries, especially developing ones, don’t have the infrastructure to provide steady, stable and clean AC power to their populations. For example, voltages can fluctuate wildly in places like Brazil; normal AC power is 130 volts but it can swing up to 160 volts or more. Argentina’s AC is normally 220-240 volts but fluctuations typically bring it up to 280. This situation is frequent in Africa, India, the Mideast, and elsewhere. Note that these over-voltages aren’t just millisecond-long surges but often continuous enough to damage or destroy your appliances.  Another factor with unsteady line voltage is transients—essentially voltage surges or spikes Appliances and electronics can often withstand some over-voltage, and by “some” we mean 10-20...

ACUPWR Hermetically Sealed Voltage Transformers

All transformers perform a same essential function by converting electricity in some way, shape, and form. It could be converting AC to DC, or from one voltage level to another, and so on. Hundreds of different kinds of transformers exist, including the international voltage transformers and converters that we make at ACUPWR. All transformers can be modified for various applications, and one such example is a process called hermetic sealing. Here, the transformer’s tank, which contains viscous liquid—usually oil—is completely airtight, sealed, and thus protected from harsh weather and environmental factors. These factors also include dust, pollution, steam, mold, and extreme cold or heat. Hermetically sealed transformers are noticeable in electrical substations and elsewhere along the power grid. They’re distinctive...

Customized Voltage Transformers, Built for Your Specific Needs

If you don’t see the voltage transformer/converter that suits your needs, don’t fret: we can build precisely what you’re looking for. Examples include step-up/step-down variations that transform between 220-240 volts and 127-130 volts, that we created for a customer in Brazil. Another example is a live sound touring company that required a few 220-240 volt to 100-volt step-down model to be used in Japan. Amongst our offerings are hermetically sealed, water-proof transformers in any wattage size up to 16,000 watts, in step up or step down (or dual operation) configurations, and various voltage transfers. Need a hermetically sealed 127-130 volts to 220-240 volts model? No problem! Need a special plug and input like a Type I plug and a Schuko...

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....

Using ACUPWR’s ADC and AUC Voltage Transformers with Wine Coolers

If you’re passionate about wine and food, you probably have a cooling device specially for wine. Maybe you’re a wine enthusiast who keeps a few dozen bottles on hand to pair with particular food, or you might be a serious collector and trader with a basement cellar containing hundreds of bottles and who often visits vineyards throughout the world and attends tastings regularly. If you move throughout the world and bring a wine cooler with you, this article will be of interest to you. Wine coolers—refrigeration devices made specifically for wine—are available in many different sizes, with a vast array of features and, generally, two different cooling mechanisms: Thermo-electric and Compressor types. Thermo-electic wine coolers use two electrical conductors to...
