400 hz. Power Supply

[brianwilliamson]

Just installed a new power supply for the seats, as the previous Cheapo from China was emitting so much RFI that I could hear it halfway down the street. This of course can cause all sorts of interference in your computers.

The new one has a very large instruction manual, but is, as always, very complex and a simple explanation for our use would have helped. It took some fiddling around to get 200 Volts at 400 Hz. but we now have it running and the RFI has been vastly improved.

For those interested here is the link:
