Hope the c word is correct English, hope you understand anyway if it's not...
Currently building a Coldamp amp with 2 smps supplies STS80 and 7 BP4078 amps.
Now, what I would like best would be every amp switching on after the other, so that hopefully the room light wouldn't dim 😀 and each amp could be automatically checked.
These amps work on 60-0-60VDC rails.
I'm not too fond on clicking relays but maybe some solid state relay could be used?
Sorry to say I don't have much experience with these things...
The BP4078 does have enable pins I think.
Thanks For Your Thoughts!

Does the smps module have a soft start circuit? If it does, I guess you can modify it for slower voltage ramping at power-on to avoid too high charge currents for the capacitor banks.
The PSUs themselves include a double soft start circuit so they shouldn't produce a too large inrush current:
First, the inrush current to charge primary capacitors is limited by a NTC.
Secondly, the controller has a slow start time of around 0.5-1second to avoid the high charge current of the secondary capacitors.
If you have any questions, just e-mail us.
