SSR03 Sjöström Super Regulator Power Supply

New product

Ultra high performance dual voltage power supply with super regulator topology. It's an unpopulated pcb. As a service you can have the AD825 soldered by me.

Interesting features

  1. Extremely low noise.
  2. Very low output impedance in the audioband.
  3. Well-known and well-tested in serious applications.
  4. Option for using three different kinds of smoothing caps, snap-in high performance, radial and axial.
  5. Option for the pass transisitor mounted on a heatsink on the pcb or with external cooling.
  6. Option for a pre-regulator LM317/337 mounted on a heatsink on the pcb or with external cooling.
  7. LM431 reference but I have made markings for anode, cathode and reference so it will be easy to mount any other 2- or 3 pin device like LM329.
  8. Trimpot for both reference and feedback in order to trim the output voltage easily.
  9. Short circuit protection via a PTC fuse and/or with a shunt and a transistor. The latter is more safe but will increase the output impedance somewhat. I recommend only the PTC fuse.
  10. All resistors 10 mm so it is possible to use a cut and bending machine for those parts.
  11. High output current, max 1-3 A but tests will determine how much. 1 ampere is garanteed.
  12. Nice looking pcb with double ground planes, gold plated pads and very thick copper, 70 um.
