The ML12 PSU is a high-quality four-rail linear power supply based around the ubiquitous 317/337 adjustable regulators. It was originally designed for the ML12 microphone preamplifier but is suitable for many bipolar circuit projects where a third positive voltage can come in handy for relays, LEDs, VU meters, control logic, etc. As such, this PSU provides:

  • 1 x Negative rail
  • 2 x Positive rails
  • 1 x Positive 48V rail for phantom power.

Using the provided BOM, the finished unit will fit in 1U rack enclosures and measures 6" x 2.5" x 1.18" (maximum height from the top of the tallest component to the lowest solder joint).
