- Q2 BD140 err in schematic - C and E flipped by mistake
- Q2 Pin 1 and R11 connected to GND by mistake.
- fuse holder for +5V should be changed
- virtual GND should be powered behind fuse
- Q2 becomes warm due to higher load on the positive supply when using Virtual GND on single ended supply.
100x100mm Optional cut in 2 where the top part can be used as a normal regulator board.
+/- 12V Supply
- Requires +-14,5v to +-27v. Input can be either linear transformer with/without bridge rectifier, or switched mode.
- Max 1,5A will require additional cooling of the regulators and larger diodes.
- Optional disable regulation
- Optional synthetic GND if only single ended supply is available.
+5V Supply
- Requires 7-25V input either as linear transformer with/without bridge rectifier, or switched mode PSU.
- Optional input from +15V thru supply
- Max 1,5A will require additional cooling of the regulators and larger diodes.
- Optional disable regulation
Thru
- Both 7V and +-15 input sections can be sent thru to a second module for daisy chaining of modules.
Reg out
- Regulated outputs can be send out to other power distribution modules or directly to Synth modules that does not require the Doepfer 10pin or 16pin power input.
