Future Sound Systems APOW3 +5Volts Adapter

Via MATRIXSYNT i recently discovered Future Sound Systems, a (small?) company in the UK that produces neat Eurorack modules and utilities.

Future Sound Systems APOW3
Besides a few interesting modules that they mention on their site, they also make and sell their own +5Volts adapter for use with Eurorack-modules that need the extra 5 Volts like the Doepfer A-190-1, the Doepfer A-113 Subharmonics Generator and various modules from other brands like for example the Mutable Instruments Braids Macro Oscillator that is shown in this next video.

The FSS APOW3 is basically a 10-pin to 16-pin Eurorack adapter with some electronics on it.
They are compatible with all types of Doepfer-style modules and provide a 100mA +5V supply.
The video below shows how it works and how to install it.

How to use the FSS APOW3 to power Eurorack synthesizer modules which require a +5V supply, without having a +5V rail from your system's power supply.

It looks like a pretty good alternative to Doepfer's own AD5 low cost adapter module, but the cost of this APOW3 is even lower... 
...and also a lot easier to install as the huge old Doepfer A-100NT5 5 Volt power supply which was 'suitable for qualified personnel only because of electrical safety'. (Doepfer doesn't sell these adapters anymore.)

Installing the A-100NT5 +5Volts Adapter (old type)

Some of the A-100 modules, for instance the A-113 Subharmonic Generator and MIDI-modules A-190 or A-191, need an extra 5 Volts power supply.
The old way was by doing this with the A-100NT5 5 V supply, but because installing it was 'suitable for qualified personnel only because of electrical safety' Doepfer doesn't sell these adapter anymore.

The 5V power supply needs to be mounted near to the main power input, on the blank upper back panel with four stand-offs, nuts, serrated washers, and bolts. 
Newer back panels (since summer 1999) are already equipped with the 4 mounting holes required for the 5V supply.

If you are considering installing and connecting the A-100NT5, it’s crucial to take note of the following safety instructions:
• The installation and connection of the A-100NT5 must only be carried out by a qualified electrician or technician.
• If no suitable expert is available, the rack must be sent to a service centre or direct to Doepfer Musikelektronik
for the power supply to be fitted.

• Danger! Before installation and connection of the power supply, it is essential that the whole rack is isolated completely from the mains current.


Note: The new A-100 AD5 5 V adapter module can simply be plugged into a free socket on the bus board; The current is taken from the 12V supply!
