Typical application

The scanning electron microscope

Scanning Electron Microscope

EBM power mainly for scanning electron microscope provided: Acceleration power, bias and filament power supply. Weisiman EBM of high voltage power supply power supply dimensions, packaging, cost, performance, there is a significant advantage. Accelerating voltage with very high stability, low noise, low ripple, 200UuA current, the output voltage programmable from 0-30KV. Bias and filament power supply suspension in accelerating on the power supply. Power arcing, overvoltage, short circuit, over current protection.
