Hello ,
I finally bought this reciever which the buyer had got from USA and i am now looking for a 120 V convertor. Anybody using a AVR bouught from USA ? Any suggestions on the convertor.
Maybe this has already be discussed in the forum. Any pointers to that would also help.
thanks
Sachin
You need a simple Step Down transformer. At the input side (Primary) you feed 230V AC and at the output side (Secondary) you will get 120V AC. Remember trasformer can change voltage level but not the frequency, so after this Voltage Step down business , you AVR will operate at 120 V AC, 50 Hz. 50 -60 Hz doesn't make any difference as far as AVR is concerned.
Don't buy any ready made voltage converters, as most of them are meant for some small portable appliances such as Shavers, Hair Dryers etc . Get one such transformer made to your specific requirements.
Things to note here are:
1> Voltage ratio 230 -> 120 (or 230->110 V) check your AVR back panel for correct voltage level.
2> Current rating: Your AVR back panel will tell you power consuption in Watts. Divide it by 120 (or 110 as applicable) to know current rating, add some safty margin say 50% more to that.
3> Insist on high grade copper wire.
4> Insist on CRGO stampings to minimize heat (loss) and Hum.
5> Mount the transformer on a sturdy wooden platform.
6> Add good terminal strip with brass contacts, you need US style plug sockets . Easily available here in India.
7> Get a protective grill on the transformer.
A well made trasformer with above specs will cost you between Rs 1000 to Rs 3000 depending on current rating.
In your city check for any trasformer maker (small capacity) or check with anybody making UPS/ Voltage stabilizer for any pointers.
If you are in Bangalore, contact Mr Murthy, he will make one for you.
Hope this helps
