BOM_PSU_rev1.1_2020-08-09_17-15-03.xls

for SW1: don't use the MTA header


Build:

just install all parts from the BOM. use Glimmer(isolation) in case you attach both regulators to the same metal/cooler


for the switch  SW1 - don't use a header - connect directly cables to SW1.

use the trimmer to get the correct voltage

...

for the secondary fuse use a value which is 10-20% bigger than what your device ask (for example a TTSH works great with 2x  500mA fuses and should be work with a 320mA too (depends on the additional mods)
