A-100 Analog Modular System - Accessories and Spare Parts

The prices for the A-100 accessories you find in the price list in the section A-100 accessories or in the section spare parts.
As we are not an electronic distributor the prices for spare parts are high compared to the prices of an electronic distributor. So we suggest to order these parts only as spare parts and not for building other equipment. For the A-100 frames we use the 19 inch housing system of the German company Gie-Tec (www.gie-tec.de). Here you may get 19 inch housing accessories that fit to the A-100 system. But as we use the 19" standard the A-100 front panel may fit with frames from other manufacturers too. Doepfer only offers ready built A-100 frames, i.e. with built in power supply, bus boards, top/bottom/rear cover, mains inlet, power switch and fuse holder. Doepfer does does not offer single mechanical parts of the A-100 frames (like mounting rails).

The prices can be found in the price list in the section A-100 accessories 

Important technical note
In the new version of the A-100 bus board (labeled Version 6 / 2019) boxed pin headers are used which are equipped with a reverse protection (gap for the “nose” of the socket of the bus cable). When the bus cable coming from the module is connected to the boxed header in question the “nose” has to point to the right. The polarity of the cable is correct if the red wire of the bus cable then points to the bottom (to the continuous line labeled “RED WIRE” on the pc board). If this is not the case please do not connect the module to the bus board ! Otherwise both the module and the power supply may be damaged !  In that case please contact the manufacturer of the module and ask for a suitable bus cable with the correct polarity of the connector.

The bus cables of original A-100 modules manufactured by Doepfer are equipped with suitable bus cables since 2012. Only for older A-100 modules manufactured before 2012 it may happen that the polarity of the 16 pin female connector of the bus cable is wrong ("nose" points to the left when red wire points to the bottom). This is because in the past unboxed pin headers were used and the position of the “nose” did not matter. In such a case please contact Doepfer or one of their dealers and order a new suitable bus cable.

General technical notes A-100PSU3

Internally the A-100PSU3 uses a +/-15V switching supply (wide range input 100...240V for mains voltage) followed by the classical linear regulation circuit of the A-100PSU2 that generates the required +12V and -12V. Only the +5V is a pure switching supply without linear regulation. We discovered that a pure 12V switching supply was not good enough for the modular system (especially the generated noise and the load regulation was not satisfying for all 12V switching supplies we tried). That's why we added the well-tried linear 12V regulation of the A-100PSU2 to the 15V switching supply. As the current for +12V and -12V is different the currents for +12V and -12V are specified separately for all modules.

Technical note concerning the +5V fuse of  A-100PSU3

The +5V of the A-100PSU3 are equipped with a separate (hidden) fuse. The fuse is located on the pc board of the A-100PSU3 next to the +5V terminals. To reach the fuse it may be necessary to remove the power supply cover (2 screws). It's essential that the mains cable is disconnected before the cover is removed ! It's not sufficient to operate the mains switch only ! From the factory the A-100PSU3 is equipped with a 2A fuse (F/fast). If required the value can be increased up to max. 4A. But this is recommended only if really a higher current than 2A is required.

Notes for replacing A-100PSU2 by A-100PSU3

An existing power supply (A-100NT12 or A-100PSU2) can be replaced easily by the new A-100PSU3 because the A-100PSU3 has nearly the same dimensions and the four mounting bolts are at the same positions. No soldering is required because removable flat connectors are used for all connections. Nevertheless the replacement or installation has to be carried out by qualified personnel only because the correct wiring of the mains connection is essential. And it's essential that all parts that conduct mains voltage (cables, pc board, electronic parts on the pc board) are mechanically protected against any contact with the human body (touch-proof, e.g. by using a cover for the power supply). Otherwise there is Danger to Life ! Existing bus boards can be used. There is no need to replace the bus boards. Only if the +5V supply is required one has to add the cable(s) that connects the +5V terminal of the bus board(s) to the corresponding terminals of the A-100PSU3.

A-100MNT/MBP

 

A-100 Miniature Power supply and bus bord (A-100MNT / A-100MBP)

Different versions of the A-100 miniature power supply are in circulation. We will mention all versions at this point but only the latest version 4 is available. All versions are ready built and tested pc boards and include a small power supply with an integrated bus board with four bus connectors. The main application if the miniature power supply is the power supply for one or a few modules only (up to four/five). The miniature power supply is also used in the miniatur case A-100MC.

  • Version 1.0 (recognizable by the small blank heat sinks as shown in the left picture, no longer available): +12V/100, -12V/100mA, +5V/50mA, requires a 9VAC adapter (i.e. 9V AC not DC), min. 300mA
  • Version 1.1 (same as version 1.0, but with larger, black heat sinks, no longer available): +12V/200mA, -12V/200mA, +5V/50mA, requires a 9VAC adapter (i.e. 9V AC not DC), min. 500mA
  • Version 2 and 3: +12V/200mA, -12V/200mA, +5V/50mA, requires a 12-15VAC adapter (i.e. 12-15V AC not DC), min. 500mA
  • Version 4: five boxed pin headers (instead of four unboxed pin headers of the former versions, +12V/200mA, -12V/200mA, +5V/50mA, requires a 12-15VAC adapter (i.e. 12-15V AC not DC), min. 500mA

Technical notes:

  • devices manufactured until about end of 2016 (versions 1.0 and 1.1) require an external transformer (AC/AC adapter) with 9V AC voltage output and are named A-100MNT. Running the old version with the external supply of the new version (12-15V AC) will damage the built-in power supply !
  • devices manufactured from about 2017 (version 2) requires an external transformer (AC/AC adapter) with 12-15V AC voltage output and are named A-100MBP (Miniature Bus/Power supply).
    • These units are either marked by a label with the words "12-15AV/>400mA". The label is located on the pc board of the power supply.
    • or the pc board is equipped with an imprint "A-100MBP Miniatur Bus/Power Supply" and "12-15V/>400mA
  • If there is no such label or imprint it's version 1.0 or 1.1 and the above mentioned 9V AC supply is required.
  • When the +5V supply is used up to 50mA are available. But the +5V current is taken from the +12V line and is missing for +12V (when e.g. 50mA are taken from +5V only 150mA remain for +12V)
  • external power supplies with DC output (instead of AC) are not suitable ! In this case only the positive or negative supply voltage will be present (depending upon the polarity of the DC supply).

Available with or without AC/AC adapter (only version for 230V mains voltage and European mains connector available)

Comes without mounting material (e.g. screws, spacers, nuts, washers) as the requirements for these parts depend upon the case (especially material and thickness of the case material)
