EuroSynth Power Supply
and Busboard Solutions

A selection of power supply kits and modules to suit most needs

The following products do NOT involve mains wiring or circuitry
and are suitable for most CCK skill levels.

A PCB-assembly power unit providing +12V @ 1.2A and -12V @ 600mA.
Requires approximately 45mm height clearance.
Powered from a 15VDC external power supply (linear or SMPS).
Output connections are via 1/4" tabs.
Our 4HP Power Panel or Power Plate are recommended as solutions for getting power in to the ED122 Power Unit.
The assembly requires a height clearance of 50mm so is best suited to deeper racks/boats, a high-clearance zone within a boat/rack or in a custom housing.

A rack-mounting power module providing +12V @ 1.2A and -12V @ 600mA.
Requires approximately 45mm depth behind the front panel.
Powered from a 15VDC external power supply (linear or SMPS).
Output connections are via 1/4" tabs.

A 4HP rack-mounting power panel provides user access to the DC in socket, ON/OFF switch and power status LED.
Can be supplied in either of 2 configurations:-

  1. SINGLE MODE - This mode is used when the system has an internal DC-Dual DC power supply such as our ED111, ED126 or ED705. The external supply for these boards is 15VDC.
  2. DUAL MODE - This mode is used when the system only has passive busboards such as our ED123 or ED704. Two external supplies are used and they must both provide a well regulated +12VDC and have floating outputs.

Output connections to the busboard are via flying leads terminated with 1/4" tabs.

A small (64mm x 35mm) Power Plate can be mounted on the back or side of your case to provide user access to a DC in socket, ON/OFF switch and power status LED.
Output connections are via flying leads terminated with 1/4" tabs.
Rocker switch version now available

This adaptor connects to a power output on any busboard and provide a 5V @ 500mA supply. The adaptor has a pass-thru mode that allows a module to be connected to the same power output.

Two options are available via an onboard jumper:-

  1. Module-Only: This provides 5V only to the module connected to the adaptor. This helps isolate the module from any noise on the busboard 5V rail as well as reducing noise being fed back on to the busboard 5V rail.
  2. Loopback: This, in addition to feeding power to the connected module, also feeds the 5V back on to the busboard 5V rail for powering other 5V mdoules. Only ONE module should ever be connected to the busboard in this mode. If your system has multiple busboards then you can attach a EURO-5V-loopback to each busboard thus maximising the power rating of the overall 5V supply
This small low-profile power unit provides a 5V output with a loading capacity of up to 3A. Ideal for heavy-load modules like the Metasonix R55 which have a high initial warm-up loading (inrush current).
Designed to run from the systems 15VDC supply but can run from a separate supply as low as 9VDC.

This small low-profile power unit provides +12V @ 2A and -12V @ 750mA or -12V @ 1.5A and runs from 12VDC @ 4A.

The outputs from this unit are filtered Switch-Mode.

This would be an ideal adaptor for running your system from a 12VDC battery.

This small unit is ideal for a 3 boat BOCGS or Serge system providing +/-12V. This unit is also ideal for small modular systems or any design requiring a dual rail supply. Available as a kit (involves some SMD), PCB assembly or a housed stand-alone unit.

The PSU-10 runs from a 12VDC external laptop-style brick and can provide +12V @ 2.5A and -12V @ 1A.

The stand-alone version is fitted with a 2.5mm DC POWER IN socket and 3x 4-pin MIC connectors for output.

A small module that is inserted inline with a modules power cable and provides and adjustable delayed ON for the +/-12V rails.

Ideal for modules with a high inrush current, helping to ensure that the main power supply can start up cleanly.

Will support power rail loading up to 1A and has an adjustable delay period up to 10 seconds

Designed to be mounted inside your cabinet.

This would be an ideal adaptor for running your system from a 12VDC battery.

Most 4U systems run from a dual-rail supply of either +/-12V or +/-15V. Some older designs, however, also require a 3rd power rail of either 5V or 6V. An example would be the 73-75 panels.

This utility PCB is desigend to be installed in to a boat that only has a dual-rail power supply and generates the 3rd-power rail.

The PSU12 can be configured to generate other rail voltages by chaning the value of R1 .

 

The following products involve mains circuitry
and/or wiring and are supplied as OEM.
These MUST only be handled by skilled electricians

A more sophisticated dual-regulator circuit recommended for bigger systems
This kit lets you construct a mains AC to pre-regulated DC power supply module
A complete self-contained AC-DC power module. Supports 115VAC/230VAC supplies and incorporates a dual high-quality regulated DC power suppply
Power Module
A complete free-standing AC-DC power module.
Has a wide-range AC input (100VAC-240VAC) and delivers +/-15VDC @3A per rail.

EuroSynth Busboards

Our Euro-Synth busboards offer a range of both powered and non-powered busboards for Euro-Synths and
have been tailored to fit seamlessly in to our Studio Series of Euro-Synth rack systems.
All of the busboards use a common footprint (205mm x 1001mm) allowing for easier interchange of boards.
The busboards fit neatly in to a 3U 42HP sub-section of your rack and are easily linked together to provide
larger power distribution and, optionally, increase power capacity.

Please refer to 'Recommended Power Distribution Configurations for the Studio Series of Enclosures'
for recommended combinations of our powered and passive busboards

Module

Description
Active Linear Powered Busboard

This busboard provides 12 independently regulated module outputs.
Each +12V outlet can deliver over 500mA to its modules.
Each -12V outlet can deliver up to 300mA to its module although the total loading on the -12V rail across the whole busboard must be less than 700mA.

ED123

DISCONTINUED
See ED704

Passive Busboard
12x passive module outlet points. The ED123 is used to increase the number of modules that can be installed in to a system. Requires a well regulated +/-12V supply.
