From the project

DIY Eurorack power supply — 3× Meanwell IRM modules (±12V/5V) with LM350/LM337 linear regulation, KiCad design.

DIY Eurorack power supply based on three Mean Well IRM AC/DC modules, with linear post-regulation using LM350 and LM337.

The design was developed in KiCad specifically for Eurorack modular synthesizers, with separate power sources for the positive and negative rails and a dedicated +5 V supply.

- +12 V / -12 V / +5 V Eurorack power rails - 3× isolated Mean Well IRM AC/DC modules - Linear regulation of the ±12 V rails - LM350 positive voltage regulator - LM337 negative voltage regulator - Dedicated +5 V supply - Filtering and decoupling - Heatsinks on the linear regulators - KiCad schematic…
