The filament and Wehnelt voltages are floating on the accelerator voltage. The Wehnelt voltage is derived from the floating precision bias supply. All three are remotely programmable via an RS-232 or USB data port and connected to a SEM through a conventional 3-pin Federal connector. A plug-in terminal block connects 24VDC input power, an external safety interlock and a HV On status bit.
The Model 3603 has two status lights which show serial communication activity and a heartbeat lamp that indicates the Model 3603’s processor is active.
CPS provides a C-language demo program which allows controlling all supplies and reports communication activity. It displays the set-point of each supply, the actual measured outputs and an internal temperature sensor.
OEM quantity 2-9 pricing for the Model 3603 is $3,405. Volume discounts are also available.
