INT-150 from 230v to 240v?

didbox · 20th November 2012, 04:36 AM

Hello,

I have a INT-150 integrated amp and it is setup to operate at 230v. As the main AC in my appartment is 239v, is it possible to change it to 240 volts?

Thank you for your help.

9V is 3,9% increase

Hello,

Really no risk to damage the amplifier? It represents a considerable budget for me and I don't want to take any risk to damage it!

send an e-mail to PL , along with serial No. of your amp

that way you'll have proper information , in time

NP is not reading all posts here

another way is that you post some pictures of internals ( xformer wiring ) and I can help , but let's do it in right way

230 on 240 is not risky , if that 239 is just higher voltage on standard 230Vac mains

but - if your standard voltage is 240 , then you must count on usual 10% rise , and that will be too much

so - important question - is 240 standard voltage in your area ?

if 230 is , don't worry - amp is made for that

In Belgium, the nominal value is 230v with a tolerance of 10%.

In my building, I have almost 238v - 239v which is in the tolerance. I suppose that in that case, it would be better to change the amplifier from 230v to 240v, no?

I don't think its an issue in practice. In the UK we had "240V" for decades, then several years ago it was "rebranded" to 230V to supposedly bring us into line with other countries.

Only the tolerance changed from the old historical -/+6% to a new +10/-6% so in reality nothing really changed and we still see voltages near to 254 on a "good" day

Even if it is not really a problem, if the amplifier can be changed from 230v to 240v, it would better for it, no?

no

because mains voltage is fluctuating to both extremes (from nominal 230Vac ) , what's absolutely expectable

and amp is made for that

case solved

OK, thank you for your help!

We see to it that the amp is happy at 230 and 240. There is a slight
difference in power consumption, but it's all allowed for.
