Isolation step-down transformer (Kolkata)

[mandark]

I'm looking for a 0.5KV isolation step-down transformer (convert 220v to 110v) for my blu-ray player in Kolkata.

I visited the outlet of "Sen & Pandit" (located at Chandni Chowk). The sales representative quoted a price of 2,800 + VAT for a 0.5KV transformer. But he was not able to say if the transformer was isolation or not.

I also contacted "Shah Electronics" (makers of MAXINE brand of transformers). They quoted me 3,250 for the transformer and 1,450 for auto wound (with enclosure, 1no. output socket 110v and mains cord) + VAT.

What is "auto wound"?

I would be interested in what fellow members from Kolkata are using for devices (specifically US ones) which needs a step-down transformer.

You don't need a 0.5 KVA transformer for your blu-ray player alone. Blu-ray players hardly consume 20W. Look for smaller VA converters like 50W and save your money.
