  • Service & Support


The LE series of regulated DC-to-DC converters deliver up to 30 W of low noise, highly controllable, stable power. The series includes nine models that range from 1000 to 30,000 VDC. The models are available in single output positive or negative polarities and use 24 VDC inputs. Electrical and mechanical integration options can be factory-configured to meet your specific application needs.


  • Improve measurement repeatability, resolution, and long-term tool reliability
  • Enable more consistent high voltage performance in varying ambient temperatures and line loading conditions
  • Enhance high voltage output performance
  • Minimize control signal noise and drift
  • Simplify integration with responsive control of module performance
  • Fast track electrical and mechanical integration tasks


  • Low ripple output performance
  • Available temperature coefficient to 25 ppm/⁰C (optional 10 ppm/⁰C 1LE to 15LE only) with line regulation less than 25 ppm
  • High voltage output control via differential analog inputs
  • Full-featured 0 to 10 VDC control; interface includes voltage/current controls and monitors
  • Electrical performance and mechanical integration options
