Balanced mains transformers, surge protections?

[Ali Tait]

I'd like to give one a go, it's the prices that put me off!

[Ali Tait]

Well Dave, whichever way you go I would be very interested in hearing how you get on with the 5 kVA unit if you get it

With regard to SM PSU the answer of course is not to have any on the dedicated spur

+1.

Ali, if you ever bought one i have a very strong feeling you'd never want to be without one I don't know about the Premier as it's different & much more efficient so must work on a different principle, but the earlier Powerplants are a revelation when powering front end kit.

It gives that dead of night sound all the time. When everyone has fecked off to bed & the mains is cleaner....

To me that's worth a lot!

[Ali Tait]

Aye, I'll get round to one sometime. So it's no good with amps then?

I used to have the P500 was really nice but now very happy using just decent balanced mains unit which I perfer. Sometimes after long stints it makes a noise from the transformer thats in the background that would be my only real issue with mine. But you cannot hear this most of the time and never when the music is playing.
I also have dedicated spur with all new boards and its still makes a difference but I do have factories quite near me
I have no idea of this is right or wrong but I think the quality of the transformer can make a difference

Not with mine, the small one can draw over 1200W when pushed

What was the rating? 4.7% sounds like it was about 500VA maximum. There is such a thing as transformer regulation & the bigger you go the less this becomes. A typical 3KVA transformer will have a regulation of about 3%, 5KVA maybe 2.5% or less

1500VA

[Reid Malenfant]

1500VA

Hmmm, something like this then I just looked at Airlinks 1500VA toroidals & they are about 4% regulation, perhaps due to winding resistances because of the higher than average output voltage it makes it a tad worse

[jantheman]

They have changed the cases but the one I have is a BPS1500...maybe about 2 yrs old now.

Just placed an order for one of these:

I hear the sense of having as big a power supply as possible but decided to go for the 3.12kVA as opposed to the 5kVA on cost grounds. That VAT hike is a killer

Anyway, as I am going to install it in the loft in the direct path of the dedicated mains cable a screw terminal device is to be preferred to the socket outlets.

I'll report back my experiences in due course.
