The Doepfer A-100DIY1 is a complete power and hardware set designed for building your own custom Eurorack case. It includes a PSU with an external transformer, two bus boards, four 84HP rails, and all necessary cabling for internal power distribution. Also provided are building templates and layout guides to assist with case construction.

The PSU delivers ±12V at up to 1200 mA per rail when used with a suitable external AC transformer. It’s a safe, low-voltage system with no dangerous currents exposed inside the case. The included rails come with M3 nuts for flexible module mounting, and the open format allows easy adaptation for different case sizes and materials.

Ideal for users who prefer to craft their own enclosures, the A-100DIY1 provides a reliable electrical foundation for personal or studio modular systems.
