Make sure your transformer is up to it - big caps can mean higher peak
currents and more I^2xR in the windings.
## I thought the same thing. I used PSUD to see the results with
In actual usage, there is no issue.....provided the xfmr is the low Z
which most are. The ones that heat up a bit are always the high Z
types..... made for choke input supplies.
Yes, for any decent transformer it's not normally a problem - my comment
was meant as a caution against taking it for granted. I've seen it where a
transformer (not a choke input type) was marginal for the load so voltage
was sagging and someone thought they would add lots more C to try and prop
As you say, PSUD is your friend.
Not all transformers designed for SS and capacitor input are low resistance.
Ive come across several 1-4 kVA units designed for FWB that have 2-4 times
the winding resistance that many seem to take for granted as being fine for
all sorts of wild amounts of C.
