Isolated DC-DC Converters

Isolated DC-DC converters convert a source of direct current (DC) from one voltage to another, and contain an electrical barrier between the input and output to improve safety. They are suitable for a range of applications, including telecommunication equipment, industrial equipment and consumer electronics.


What are isolated DC-DC converters used for?

Isolated DC-DC converters are used within equipment and devices containing different circuits or sub-circuits where it is necessary to convert the voltage of a DC supply from one level to another. For converting AC to DC, an AC-DC converter would be used.


Types of isolated DC-DC converters

Isolated DC-DC converters come in a wide range of input and output voltages and a variety of mountings, such as:

  • Chassis mount
  • DIN Rail mount
  • Flange mount
  • PCB mount
  • Rack mount
  • Surface mount
  • Through hole

The advantages of isolated DC-DC converters:

  • Meet international safety standards and regulations.
  • Electrical isolation provides additional safety to personnel in case of internal failure.
  • Wide range of voltage conversion with high efficiency.

Certain models are railway- and medical-approved.
