We are offering power supplies for scanning electron microscopes. Power supplies for sems are integrated systems consisting of multiple power supplies (high voltage power supply and filament supply floating on high voltage) that are characterized by extremely high regulation and stability. • voltage regulation (line and load) : 0.005% • current regulation (line and load) : 0.01% • stability : upto 0.01% per hour after ½ hour warm-up, 0.05% per 8 hours
