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.
