Housed in 25 x 12 x 20 cm enclosure, Model 3603 comprises 3 power supplies used by SEMs and inspection systems: -30 kV at 330 µA accelerator, -1 kV at 25 µA Wehnelt, and 5 Vdc at 3 A floating filament. Filament and Wehnelt voltages are floating on accelerator voltage. All 3 are remotely programmable via RS-232 or USB data port and connected to SEM through 3-pin Federal connector. Plug-in terminal block connects 24 Vdc input power, external safety interlock, and HV On status bit.
