Reversible Polarity & High Stability

KS-R series are compact HV power supply. Features of KS-R series are ultra low ripple and high stability. It is the perfect choice for SEM and MASS applications. It is possible to change the output polarity at high speed with external signal.

Features and Benefits

  • Designed for SEM, MASS and E-beam, I-beam applications
  • High speed polarity change 250 ms (10 kV type)
  • High Stability
  • Ultra Low ripple noise
  • Output voltage, current monitor
