- Max Current: 5 A
- Rated output Power: 37.5 W
- Isolated voltage : 30 kV
COMPACT FLOATING FILAMENT POWER SUPPLY FOR ELECTRON AND ION BEAMS
The FDC series is a constant current DC power supply specifically engineered for floating filament applications. Despite its compact chassis-mount design, it provides high voltage isolation of up to 30 kV. This series ensures stable performance for driving filaments in electron guns and ion sources, making it an ideal choice for Scanning Electron Microscopes (SEM), Mass Spectrometry (MS), and X-ray tube applications.
