Compact ±12 V power supply module
An ultra-compact 4 HP power module for small and medium modular systems. It turns an external +12 V DC adapter into stable +12 V and −12 V Eurorack rails, with proper filtering, protection circuits and a Reverse-Action Safety Switch that prevents accidental power-on during patching or transport.
Features
- 4 HP compact format — ideal for skiffs and portable cases
- Stable ±12 V rails based on the MC34063 converter
- Reverse-Action Safety Switch — reversed switch logic, so an accidental press will not turn the power on
- Reverse-polarity diode, resettable PTC fuses, input/output filtering
- LED indicators for +12 V and −12 V
- BIGZUN signature panel with maths/electronics artwork
- Requires an external +12 V DC adapter (1–2 A recommended, 5.5/2.1 mm barrel)
- Bus board or flying bus cable not included
