NJ Micro Electronic Testing, Inc. (NJ MET) tested an ACUPWR AUD-500 transformer and a PowerBright VC-500W transformer in comparative side-by-side electrical testing. NJ MET engineers found the ACUPWR AUD-500 to be more efficient, better at generating specified voltage, and safer. The ACUPWR AUD-500 was manufactured in Wisconsin, USA and the PowerBright VC-500W was manufactured in Suzhou, China.
NJ MET, Inc. is an AS9100 & ISO 9001 registered company in operation for 40 years and is a full service laboratory for testing electronic components and counterfeit detection of electronic components. NJ MET, Inc.’s main offices and laboratory are in Clifton, NJ.
Both models are step-up/step down power transformers, meaning that they can convert voltage from the wall up or down to meet the requirements of an electrical device. NJ MET engineers test how they performed in step-down mode, converting 240 voltage down to the 120 voltage commonly used in the United States. This would allow usage of US standard devices in a country where 240 volts is the standard.
