choosing a bleed resistor

[Clive S]

Hi Doddy
I'm using a 500va 2x18volt toroidial transformer with 3 or 4 4700uf 100 v caps. 35 amp rectifier in my power supply, would the elektor circuit be ok with that power supply ? or should I hunt around for another soft start circuit ? Thanks in advance.
cheers

Andrew

Personally I don't think you need one. I have a 625vA one that runs without any trouble and 3 caps is ample.

Hi Clive
I'll put one I found on ebay https://www.ebay.de/itm/131927219743 in just not to strain my wiring. It's an old house in the country here in Austria with a new distribution box wired up about 15 years ago which happens to be in the workshop as well so cable runs are not too long. A little peace of mind is worth the added expense for me.

Hi Clive S,

You helped me with the parts list for the diy psu i have.

500va 2x25v.


No problems here either on 16amp B type CB.


Andrew, do you have issues on the mains power side?



In rush limiting is ok but not really needed when mains side is no problem.




Grtz Bert.

Hi Bert
I haven't put the supply together yet but it's an old house and I don't want to overload the the circuit breakers so it's really just for a bit of added protection.

Cheers
