DESCRIPTION
Pins 1 and 2 should be interconnected to
use power supply in stand-alone regime
In this case, high voltage will appear at
the power supply output once HVPS-300
is powered
Pin 2 or 4 should be pulled to the ground to
enable the output. Output is disabled while
TTL high level is applied to pin 2 (4) or pin
2 (4) is left unconnected
To use power supply in stand-alone regime,
pin 2 (4) might be short-circuited with one
of Interface return pins (e.g. pin 1)
Output voltage monitor
Calibration is linear, 10V on pin 3
corresponds to V
at the output
MAX
Return of all Interface signals (Enable, HV
Monitor, Fault) except HV Program
-
Return of HV Program signal
In order to improve high voltage stability
isn't connected to the common ground of
Interface
5V if fault occurred, 0V elsewise.
Fault state is set in the next cases:
•
Overheating of HVPS-300
DC voltage applied between pins 9 and 7
sets up the high voltage level
Calibration is linear, 10V between pins 9
and 7 corresponds to V
MAX
Pins 9 and 10 should be interconnected to
use power supply in stand-alone regime
In this case output voltage is defined with
HV Program trimming potentiometer
Clockwise rotation decreases HV value
Counterclockwise rotation – increases HV
value
at the output
