Step down transformer recommendation for Denon Avr x4400h

[Chaitu124]

Hello All ,
I'm getting a Denon Avr x4400h from Canada. It is rated at 120 V, 60 Hz 710 W.
I'm planning to buy below transformer for 10k to get the av receiver running in India.
MAXINE 1.5 kVA/1500 Watts Copper Auto Wound Voltage Converter 220 V to 110 V Step Down Toroidial Transformer https://amzn.eu/d/3kcmJqr

1. Can you please share your thoughts on this ?
2. Is there any chance of Buzz or humming noise ?How can we reduce that?
3. Should I hookup a voltage stabilizer before step down transformer? If yes, please recommend the specifications.

Thanks!

Welcome,
Maxine setup down transformers are good with no buzz or humming noise in my setup.
Using the same with my Denon x3100 for past five years.
Better to add a stabiliser.(am using an online inverter)

Thanks for the response.
I found below one is the best with Inbuilt Stabilizer.

You can safely go with Maxine. They are good

Actually having a step down transformer before the AVR is a good idea. As long as the step down does not hum. The transformer will burn first, and protect the AVR if there are any very high voltage peaks.

Thanks for the suggestion. I got to know that, an online inverter can do the work of a voltage regulator + circuit breaker + power backup.
As I'm taking 1500w Stepdown transformer, Can I get the UPS of same ratings ?
Can you please give the name or link of the inverter you're using ? I haven't dealt with UPS, so this can be a starting point. Thanks!

Hope the 50Hz does not fry your 110V power transformer of your AVR. Simply stepping down is not the solution. You have no control on frequency. There may be many FMs swearing by Maxine and so on and AVRs working without issue but in the long run it harms the transformer.

Being an electrical engineer I will try to replace the power transformer with a 240V, 50Hz equivalent or would get a AVR that is dual voltage & frequency compatible.

This is correct. @Chaitu124 try to get a 240v to ( 110v & 60hz ) step down from canada as it might be 60hz there.

Most step down's I've seen in India are 50hz only. And 50hz can fry a lot of stuff. I have a Power regenerator with variable frequency output ( 50 to 70 hz variable ). And it is clearly mentioned not to run CD players or turntables with wrong frequency setting as it will burn the motor.

That won't help. Even that step down transformer from Canada or anywhere else may not withstand the 50Hz supply.

Frequency is set by the power system. You cannot change. Only a handful of countries have this 60Hz system.

Basically the operating frequency decides the core size and core size of 60Hz equipment (motor, transformer etc.) will be very small. The core heats up and can lead to failure of the transformer.

Open any mobile SMPS and see the little transformer inside? It works at very high frequency and are hence miniature compared to any 240/6V transformers of same capacity.

I imported a pioneer sa 8800 from Japan which step down converter is good...can anyone suggest a good one for indian use

Look at that. Your device is designed for 50 / 60Hz. In Japan they have both 50Hz and 60Hz grid so they design their transformers to work on electrically the worst case i.e., 50Hz. Any good step down transformer would work.

Which socket must I use in india...100v r 110v
