Exceptionally Low Noise: 1.5 mVp-p Ripple

The VPS series is a chassis-mount high-voltage power supply module engineered for ultra-low ripple and minimal radiated noise using comprehensive shielding.
These characteristics make it ideal for noise-sensitive applications such as Photomultiplier Tubes (PMT), Scanning Electron Microscopes (SEM), and Electron Beam Lithography systems. The VPS series significantly enhances the precision and stability of integrated equipment.

FEATURES AND BENEFITS

  • Industry-leading ultra-low ripple performance of 1.5 mVp-p
  • Low radiated noise achieved through comprehensive metal shielding
  • Ideal for Photomultiplier Tubes (PMT) and Scanning Electron Microscopes (SEM)
  • Built-in protection features including voltage and current limiting circuits
  • Fast output discharge function for rapid voltage fall time
  • Compact design optimized for OEM integration
