Need your suggestion on step down transformer for ONKYO HT-S5400

[nityanandmg]

Hi All - I am planning to buy ONKYO HT-S5400 from USA.

Below power info I found on ONKYO website for HT-S5400.

Power Supply: AC 120 V, 60 Hz
Power Consumption: 4.5 A
Standby Power Consumption: N/A

Could you please suggest me what kind of transformer or stabilizer I need to buy so that the system donot encounter any issue.

Thanks in advance

Always power(watt)=V*I=120*4.5=540 Watt...so it will be safe it you buy a 600-750 Watt step down transformer

Thank you Krishneo.....
One more question.
Will there be any issue with step down transformer, which might fluctuate current output?
Do I need to go for a stabilizer to save my HT.

Power supplly ->step down transformer ->stabilizer ->HT

hi sorry for the late reply.... power supply==>stabilizer==>step down==>HT also is fine...if you are living in a region where power fluctuations are constant then better go for it....

To be on the safe side you should get a transformer with twice the power rating of the device. So you need atleast a one kVA or better 1.5 kVA transformer. The formula for peak power is RMS*2*1.414.

About the stabilizer, as far as I understand, voltage fluctuations will not damage your HT. The power will go through the transformer first. So it may be ok to just buy a good quality transformer and a surge protector with good fuse to use before the transformer. But please consult the person you buy from to be sure. Or experts here may advice better.

Maxine transformers are usually considered good by forum members. You can actually order it on ebay or go to a local shop and ask for it. I recently got a Maxine one for 5400/- for 1.5kVA. You may be able to get a cheaper alternative in some local shop, but I would suggest a toroidal one for low noise and size.

For surge protectors, there are many: check on ebay or a local chroma type store. Belkin are usually considered good. You can also check mdrelectronics website. Just make sure you get the one with the right power rating and ideally with a replaceable fuse.

Most of the information I have given you has been taken from this forum only. So just giving back what I got

Maxine Stepdown transformers have very good reputation in this forum.

For surge protector look for Belkin in ebay.in.
