MS0.2 Series

Precision High Voltage Module


Applications: Beam steering, Focus and bias supplies, Deflector Plates, Electron guns & Ion beams

  • High Stability, Low Ripple
  • Externally programmable - through zero control
  • Short circuit and flashover proof
  • 24 hour burn in

This power supply provides six outputs each separately programmable from -200V to +200V with respect to Gnd. It is intended for steering, focusing & biasing of electron & ion beam applications. Biasing steering plates in pairs, this can control X, Y & Z directions. Each output is controllable cleanly through zero.

Please consult the factory for special variants of this supply including high speed versions.

Electrical Specification
Input +24V dc ±0.5V <0.5A. 0V input common to HV return and chassis.
+15V dc ±0.5V <0.5A , & -15Vdc ±0.5V <0.05A.
Control of Output -10V to +10V for –100% to 100% ±2%, (Zin = 200Kohm)
Output Current 100μA per channel
Voltage monitor -8V to +8V ±2% for –100% to 100%. (Zout= 10k)
Current Monitor Not available
Ripple <25mV pk to pk
Line regulation <100ppm for 1V change in input voltage
Load regulation <100ppm for 10uA to maximum load
Temperature co-efficient <25ppm/ºC
Drift (after 1 hour warm up) <0.01% per hour, <0.05 over an 8 hour period
Protection (all outputs) Protected against intermittent arcing and continued short circuit to ground. While able to source or sink 100uA, the unit will be damaged by sustained sinking of a beam current in excess of 200uA.
