Review on 1000W Voltage Transformer Converter SEYAS with Auto Step Up and Step Down, 110-120V to 220-240V, Soft Start, Full Load Capability, 24/7 Continuous Run, Circuit Breaker Protection, U.S. Patent No. US9225259 B2 by Noe Epps

I waited a few months before posting a review. But now I'm sure it's the device. First of all, the absence of extraneous smells and absolutely dead silence copes with its task perfectly, even when it is on 24/7. I'm using this to power a DAC bought in Europe (made for 230V) to run it on 110-115V in the US. Surprisingly, unlike other converters, this unit doesn't just double the input voltage. former. A 120V input will not convert to 240V. All other devices in a similar price range I've tried have given me 220-250V with 110-125V input, but this device stayed between 230-240V and 230V most of the time, which is perfect for my DAC. AC input voltage.
