[Amps] thyristor controlled soft start?

[Peter Voelpel]

Zero crossing SSRs are no good idea, better to switch on the peak voltage.

Far better is controlled switching,

Hi group,

I'm thinking about using thyristor controlled softstart on my amplifier PSU
transformer for my next project, is there anything I should be concerned
about using this type of softstart?

On another note, my last question about transformer winders in the UK,
thanks to everyone who replied... I've decided to go with Harrison &
Greenwood (Transformers) Ltd, the customer communication has been very good
and inspires confidence... Price is good to, and that's important these
days.

Cheers,

Andy
