FA: -36VDC Hobbyist Power Supply Printed Circuit Board
See
This power supply printed circuit board is a good working unit pulled from a Sharp model R1500-series microwave oven.
At a no-load condition it supplies an unregulated voltage of about
-36VDC.
Note: I suggest you don't run it too long in the unloaded condition since the electrolyic filter capacitor is rated at 35VDC. You could install a load resistor across the cap if necessary to limit it below
The Sharp part number is CPWBFB075MRU0 (which replaces CPWBFB060MRU0) and original retail cost was .04 each. This unit does not include a display.
I have 5 of these but want to offer one to just gauge the interest. E- mail me at snipped-for-privacy@usa.net if you want more than one.
