Mean Well Power and Doepfer A-100 Bus Board – 9U Bundle

What is in the bundle:

• 2 x Mean Well switching power supply
• 3 x Doepfer – A-100 bus board
• Electric hook up wires
• Fused main switch

The Mean Well power supply is a switch mode, triple output enclosed power unit.

Power Supply each unit :
2800mA +12v,
500mA -12v
5000mA +5v.
Total output power is 65Watts x 2

It has a universal AC input of 110/230v AC.
Dimensions are: 129mm x 98mm x 38mm.
Whilst most of the components of the power supply are enclosed, the electrical connection terminal block is exposed and therefore it is essential in a eurorack case that these terminals are guarded and the installer should source a suitable guard, as one is not included. See notes below regarding installation.

The three Doepfer A-100 Bus Boards each connects up to 14 eurorack modules via 16-pin headers.  The red LEDs on the board indicate whether the correct voltage is available for the module showing the +12v, -12v and +5V.  The A-100 Bus Board includes four cables for connection to the Mean Well 12v DC power supply.
The cable lengths are approx. 300mm in length (30cm) with flat connectors at each end. The connectors fit the bus board, the connectors the other end should be snipped off and stripped back to suit the screw terminal connection of the Mean Well unit. (The A-100 bus board is also suitable for use with many other power supplies)

Dimensions of the A-100 bus board are:
390mm in length, 43mm wide, and 15mm high, without spacers.

This Mean Well power adaptor is a budget solution and not a purpose-built eurorack supply and whilst we understand there are many systems out there working well/satisfactory it is advisable to take a look at some of the forum talk around the use of these and in particular the loading requirements on the +5v rail.

Please be aware that the power supply carries mains voltage (115 or 230v AC) and connections /installation should be carried out by a competent qualified person.
