Eurorack Power Bus Board – 11 Outputs, Low Noise Design*

Eurorack Power Bus Board – 11 Outputs, +12V / -12V / +5V, Low Noise Design**
Eurorack power distribution bus board designed for reliable and clean power delivery to modular systems. Suitable for DIY cases or upgrading existing setups.
### **Features**
* 11 × 16-pin Eurorack power headers (2×8 IDC)* Supports **+12V, -12V and +5V rails and CV/Gate signals**Screw terminal or pre wired pluggable power input* LED indicators for each rail (+12V / -12V / +5V)Expansion connector carrying power rails (+12V / -12V / +5V / GND) and CV/Gate signals for linking to additional boards or can be used as extension
### **Power Design**
Each connector includes local decoupling:
 capacitors for bulk filtering ceramic capacitors for high-frequency noise suppression
This helps to:
* Reduce power supply ripple and switching noise* Improve stability of connected modules* Limit noise coupling between modules
### **Benefits for Eurorack Systems*** More stable operation, especially with digital modules* Lower risk of noise in audio paths* Better handling of fast current changes (e.g. envelopes, DSP modules)* Cleaner CV and Gate behaviour
### **Build Details**
* Standard Eurorack 16-pin headers* Clearly labelled power rails* PCB designed for good current distribution* Onboard visual power indication
### **Specifications**
* Outputs: 11 × 16-pin headers* Rails: +12V / -12V / +5V up to 6A* Decoupling per connector: 10µF + 100nF per railScrew terminal block orPluggable connector 
### **Package Includes**
* 1 × Eurorack Power Bus Board (assembled)* 1 × Power input plug with pre-wired leads (for PSU connection)* 1 × Additional plug for extension * 10 × PCB mounting spacers* 1 × Chassis earth bonding wire
 **Notes**
* Power supply not included* Check ribbon cable orientation before use
Important – Power Connection WarningPre-wired power input leads are colour coded:Blue → -12VRed → +12VGreen → +5VBlack → GND (0V)Always verify polarity before powering the boardIncorrect connection may damage modules**Simple, reliable power distribution with proper filtering – ideal for most Eurorack builds.*
