As alternative to an HPS high voltage power supply with integrated filament supply the FPS series is a dedicated current supply for filaments, often used in electron beam applications (e.g. EBPVD). The main advantage is the possibility to combine with HPS high voltage power supplies, where the filament supply can be driven on high voltage potential from the HPS. Therefore the FPS has a HV input connector and an HV-filament output connector.
