Hello All - I purchased Denon X3700H AVR from US. The power spec says 120 v, 60 Hz and 660 Watts. Can you please recommend a good step down transformer preferably with a stabilizer from your experience?

Thanks much for your help

You can try bluebird step down transformer. Many brands have come due to sudden increase in oxygen concentrator usage.

Maxine is a very old and reliable brand

Hi,

You have to take a few things into consideration.

Your choice should have atleast double power rating to your equipment. Now they come with ratings in VA.

I think you should atleast go for a stepdown rated at 1kVA.

Do note your average line voltage as well. Stepdown transformer work on ratio of input voltage to output voltage.

For example they deem the input voltage to be 220v and will give an output voltage of 120v. So the ratio is 1.83 : 1.

If you are getting 245v voltage at your place then the output of your stepdown will be 133v which is 10% higher then rated input.

It stresses the power supply and ultimately something gives.

So please bear this in mind.

Hope this helps
