803x Series Overview
The 803x power supply series provides 8 or 16 independent HV channels, whose control can take place
either locally thanks to a 2.8" Touchscreen Graphic color LCD display or remotely, via USB 2.0 or Ethernet.
The units are available in three formats: double width NIM mechanics,
19” rack
module and Desktop case.
NIM and Desktop versions feat
ure 8 channels, the 19” rack units can house either 8 or 16 channels
.
5 output ranges are available (100V/10mA, 500V/10mA, 4kV/3mA, 6kV/20µA and 6kV/1mA), with either
positive or negative polarity; all units are provided also in “mixed” version, with half
of the channels
positive and half negative. 100V channels are delivered through BNC connectors, other versions feature
SHV’s.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel.
Safety features include:
•
OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the
programmed value by more than 2% of set value (minimum 10V).
•
Programmable VMAX protection limit via front panel trimmer; common to all channels
•
Programmable IMAX protection limit via front panel trimmer; common to all channels
•
OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit,
it enters TRIP status, keeping the maximum allowed value for a programmable time (TRIP),
before being switched off.
•
Common Interlock logic for channels enable/disable and individual inputs signal for channel Kill
function.
A complete set of Software Tools is available to control these units; the User can freely download low
level libraries, LabVIEW driver and Graphical application software.
