Rectifier bridge with 4-layer pcb building question

Arick · 27th October 2009, 08:02 PM

Hi everyone,
Per Anders kindly provided us with these very nice pcb's, in the group buy with the same title.
Following my purchase, I read the instructions listed on Per Anders site. However I still have a question for you guy's.
I live in Canada and we have 120 volts with 60 hertz's, so what should be used as far as condensers and resistances with this board? Or it does not mater

Also, I found this heat-sink for the board, available at Newark, for those of us in living in North America

Newark Part Number:09R3175

You mean a line filter?

Generally, this filter cares only about frequency and 10 Hz are not a big deal. Caps across primaries must be X-rated, means if they fail, they go open instead of short.

You probably do not need to change anything, but you should mail P-A to be sure.

Have fun, Hannes

He means the value of the R-C snubber.
