Eurorack 12V to ±12V +5V Isolated DC/DC Converter PCB – 1.25A
Description
This PCB is an isolated DC/DC converter designed to convert a single 12V DC input into three separate DC output rails:
+12V DC
-12V DC
+5V DC
The board is particularly suited for Eurorack modular synthesizer systems, where these three supply rails are commonly required.
The converter uses isolated DC/DC conversion to generate the required positive, negative and +5V supply rails from a single 12V DC source.
Specifications
Input: 12V DC
Outputs: +12V DC / -12V DC / +5V DC
Maximum total combined output current: 1.25A
Conversion: Isolated DC/DC
PCB: Fully assembled converter board
Input power supply: External 12V DC supply required
Recommended input supply: 12V DC rated at least 3A for maximum rated output
Eurorack Applications
The board can be used as part of a Eurorack modular synthesizer power system, providing the required:
+12V / -12V / +5V supply rails
It can be used in conjunction with the Eurorack power bus board listed in my other sale items, allowing the converter PCB to form part of a complete Eurorack power distribution system.
Other Applications
Suitable for:
Eurorack modular synthesizers
Synthesizer projects
Audio electronics
DIY electronic projects
Test and measurement equipment
Control systems
Embedded electronics
Custom power systems
Important Information
This is an isolated DC/DC converter PCB — it is not a mains power supply.
Maximum total combined output current is 1.25A
The 1.25A rating is not 1.25A per output rail
A suitable external 12V DC power supply is required
The 12V input supply is not included
Observe correct input and output polarity
Do not exceed the rated output current
Check the voltage and current requirements of your equipment before use
Included
1 × 12V to ±12V +5V isolated DC/DC converter PCB
PCB only – no enclosure or Eurorack bus board is included.
The converter PCB can, however, be used in conjunction with the Eurorack power bus board listed in my other sale items.
