DDi Series Voltage Converters Features

A list of features for the PSU Converter are listed below:

  • Ideal for small vehicles such as marine craft.
  • 12V-12V unit provides a stable output voltage as well as providing galvanic isolation for a variety of application.
  • Click ‘n’ fit’ mounting clip which is fixed in three points allowing it to be mounted on uneven surfaces. 
  • No ventilation holes to permit stray objects, dust or water droplets to enter the case.
  • Red LED indicates when there is output from the converter.
  • No external fuses.
  • Enclosed in a rugged aluminium extrusion.
  • Vibration and shock proof.
