MODEL 3603
FEATURES

Triple output high voltage power supply: −0.5 to −30 kV @ 300 μA, 0 to +5 V @ 0 to 3 A floating, 0 to −2 kV @ 200 μA floating

  • Three outputs: −30 kV 330 μA, floating −1 kV 25 μA and 5 VDC 3 A
  • Compact enclosure
  • Interlock input and status LEDs
  • Federal Standard output connector
  • RS-232 remote control
  • Demo software with source code
  • Ideal for electron microscopes and similar applications
DESCRIPTION

Model 3603 contains three common high voltage power supplies used by scanning electron microscopes (SEM) within a compact 25 × 15 × 20 cm enclosure. The filament and bias voltages float on the accelerator voltage; all three are remotely programmable via the RS-232 data port. Connection to a SEM occurs through a conventional 3-pin Federal Standard connector. A plug-in terminal block connects 24 VDC input power, an external safety interlock, and a ″HV On″ status bit.

Functional block diagram

Model 3603 functional block diagram

Two status lights show serial communication activity and a heartbeat lamp indicates that the processor of the 3603 is active.

The bias voltage is derived from the accelerator supply and controlled by an electronically programmable Wehnelt resistor.

Software

A C-language demo program allows control over all supplies and reports communication activity. It displays the set-point of each supply and the actual measured outputs. Internal temperatures of the individual power supplies are also displayed.
