Doepfer A-100 Small Supply / Bus


The Small Supply / Bus is a combination of a power supply and a busboard with eight connectors for Eurorack modules. It is intended for DIY applications where a maximum power consumption of 380mA is sufficient. The universal power supply can be used world-wide and it even has an IEC mains inlet.



The power supply used here is a switching power supply which can be used in the entire world as it accepts mains voltages from 100V to 240V
The PSU supplies you with 380mA at +12V and 380mA at -12V. In addition +5V with maximum 100mA can be provided, but the current is taken from the +12V line (i.e. the sum of +12V current and the +5V current has to be less than 380mA). The present voltages are displayed with individual LEDs for +12V, -12V and +5V
There is a safety cover at the bottom side covering all elements that lead mains voltage. A mains fuse is located at the circuit board as well.

Up to eight Eurorack modules can be connected to the product.

The board has several 3mm holes for mounting the Small Supply to a rear panel or a base plate.


A suitable IEC mains cable is not included with the A-100SSB and has to be purchased by the customer locally.
