• Notes

• The MR 50 HS is developed to power Electron Microscopes and similar equipment. The supply provides a variable DC output from 5 kV to 50 kV at 1 mA maximum, with reversible output polarity.
  The output drift is less than 4 parts in 10⁵ over 15 min. The long term drift is less than 1 part in 10⁴ over 24 hours at an ambient temperature change of less than 5 degrees C.
  Stability against ± 10 per cent mains variation is better than 4 parts in 10⁵.
  Output ripple is less than 2 parts in 10⁵.
  The equipment is also available with built-in stabilized filament and can be isolated, to work at 50 kV from hearth potential.
