Because of 4QD's designs, most of our controllers can be made in 48v versions. It generally involves upgrading several components to higher voltage devices and the use or higher voltage MOSFETs.

Modifying individual controllers is not commercially viable, and the demand for 48v versions is generally low, so only certain models are generally available as -48 versions.

Available 48v controllers

• 4QD series
  these are wide operating voltage range: the -48 version will work between 18v and 60v max
  • 4QD-150-48
  • 4QD-200-48
  • 4QD-300-48
• Pro-120
  • Pro-120-48 - limited availabilty, minimum quantity applies.
• Pro-150 is a wide voltage range programmable controller working from 18v to 60v.
• Uni series
  • Uni-4-48
  • Uni-8-48
• Porter controller
  • Ptr-040-48 is a wide voltage range controller working from 12v to 60v.
