Simran AR-1000 Converter Transformer Voltage Regulator Stabilizer, 1000 WATT, Cream

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.

Product did not match the advertised photo with multicolored outlets which would have been a nice safety feature. But the transformer I did receive performs well beyond expectations. Measured output exceeded stated wattage, enough to support a submerged water pump, oil furnace and refrigerator (up to 25 continuous amps {3000w} with occasional rare instantaneous start-up bursts of up to 34.7 peak amps {4164w}).The regulator function is great. Voltages stay right even when fluctuations in the supply occur.BTW the transformer came through Chicago Electronics with the brand name "Superite" not "Seven Star"

It stabilized the voltage pretty exactly.. the issue with just transformers (step up / down) is that if the input voltage is slightly higher, the output voltage is too.. but here it doesn’t matter.. the output voltage is either 120V or 230V.. it also doesn’t matter, if the load is just a few Watt or the full range.. it stabilizes load independently..I really like it.. don’t waste money by buying just a step-up / step-down generator.. if the voltage is out of specific of your connected devices, they get damaged..So a clear buy!!

First, it come without instruction and seller doesn’t provide for instruction. It is confusing to wire this thing up since it doesn’t have anything to indicate which knob is Neutral, which Knob is Live.Second, when I flipping this converter up to see if anything writing at the bottom and find out that this unit is damaged, the bottom was deformed and 2 screws lost that causing the inside stuff got loose. It is heavy so I only find out when I lift 45 degree up and found that the things inside sliding down loosly.This may be a good product like other 3 reviewers gave it credit for, but my unit wasn’t the one that deserve more than 1 star and given how much trouble I am seeking for how to get this hotwiring. I am not happy with the purchase and other buyer should be aware of getting this. The seller has very limited knowledge of what he is selling.

This is the second Simran voltage transformer I have purchased, the first being an AR-4000 model. I have used them both in the UK for almost 3 years now, and have ZERO issues. One of the nice features is there is an audible "click" sound when the voltage spikes, or drops, as well as being able to see the input voltage on the meter window...and it’s comforting to know that all my electronics are still getting the same even voltage they need, and their life isn’t being shortened by the ever changing voltages while traveling.I have only one cautionary note of interest. Since the transformer is quite heavy, and shipping is quite unpredictable…I would HIGHLY suggest that you take the cover off after pulling it out of the shipping boxes. Reason is to make sure none of the wire connections where worked loose during shipping as you may notice the transformer itself being a bit wobbly/loose. My first Simran AR-4000 had the ground wire completely disconnected from the screw it was under…just from the weight of the transformer moving back and forth during shipping (it’s quite heavy).
