Simran 500 Watt 110v to 220v Step Up Down Voltage Converter Transformer with Built-in Power Regulator, AR-500

Vintage electronics usually only operate on either 110V (120V) or 220V (240V). I feel more confident using this regulator to power my vintage electronics with a consistent regulated voltage. Still, to avoid any potential accidents with the wrong voltage, I've labeled the vintage machine's AC/DC plugs just in case. Pro: This voltage regulator has a nice retro look-and-feel. Perfect to power vintage electronics. The voltage regulator is very quiet, but not completely silent, with an almost inaudible 60Hz hum. The instructions are translated to English with a few typos, which is alright. Just follow the steps described. Beware that the input voltage selector on the back of the unit must be set to the voltage supplied to the unit, which may not be entirely clear from the instructions. Cons, a minor one but may matter: The AC lead to the unit has a standard European grounded plug. A US-EU converter plug is supplied to power the converter from a US socket. This converter plug has no ground pin, which would have been much better to ensure the unit and output are properly grounded when powered from a grounded US AC socket.

good!

Unit looks used.. Fuses keep poping and the is not working.

Seems well built. But output voltage still seems to vary through when an air conditioner elsewhere on the circuit switches on and off. Nice touch that they included spare fuses.

I have traveled around the world to areas were power is not always regulated well. I have used this to save some of the more sensitive electronic items. Works well. The case had some screws that rattled out in delivery, but took 5 seconds to fix.

this item heats up after few minutes and gives hum. THE PRODUCT IS NICELY MADE BUT ELECTRICAL PERFORMANCE IS POOR.

The unit now works well and I am very pleased with the value for money, but I had some initial issues with it. First was the two pin US plug, had to buy a VCT Electronics VP13 adapter for it to be properly grounded. Second was that it was DOA; some quick fault finding identified a bad connection in the fuse on the front panel (easy fix), but during this fix noticed that the majority of the sheet metal screws that secure the cover had stripped threads and required new bigger screws on reassembly. In short, it is true stabilized power supply that works very well, it is a really good deal, but the QC and the 2 pin US plug need some attention.

Good to have if you you are travelling to Country where the Volts are 240 and you have US 120 V items to run there. I have one issue though that it does stabilizes the fluctuation of the volts that frequently happens in India, my home country.

Después de dos meses sigue funcionando bien y sin problema. Lo recomiendo, producto muy robusto y confiable, de buena calidad.
