Adrian,
Just use a NTC and you can just put it in the same cabinet.

Subject: [Amps] Step Start Relay
Hi all
I am near completion of the re-build of the power supply of my Dentron
ML2500 linear, and all is well. I now wish to add a Step Start facility.
However, there is limited space within the case of the linear so an
external step start would be in order. (I also have a TL922 as well as a
home brew 144MHz Linear, all of which would benefit from a step start
facility).
I was wondering what duration of delay to use with the step start. I
think about 250mS - 500mS would be about right. What are the groups
thoughts on this ?
I have a delay relay that will do the job, as its contacts are rated at
500v at 16A (AC), although the shortest delay on this relay is 1 second.
Thoughts anyone ?
Thanks
Adrian MW1LCR
