Control inputs
•
Remote Control Voltage (CV)
V
V-SET
= 0 to 5 V
The output voltage is proportionally to the external control voltage of 0 to 5 V DC between
pin 8 (+ V
V-SET
, indirect coupled) and pin 6 (@GND, indirect-coupled).
Example: HPp 40 357, maximum voltage = 4 kV
V
V-SET
(V)
Output voltage (kV)
5.0
corresponds to 4.0
2.5
corresponds to 2.0
1.0
corresponds to 0.8
•
Remote Control Current (CC):
V
I-SET
= 0 to 5 V
The output current is proportionally to the external control voltage of 0 to 5 V DC between
pin 4 (+ V
I-SET
, indirect coupled) and pin 6 (@GND, indirect-coupled).
Example: HPp 40 357, maximum current = 350 mA
V
I-SET
(V)
Output current (mA)
5.0
corresponds to 350
2.5
corresponds to 175
1.0
corresponds to 70
•
INHIBIT
TTL level
High voltage generation will be
shut off
with help of the TTL-level
LOW
on pin 3 related to GND -
analogue (@GND-analogue indirect-coupled to GND-HV and metal box).
High voltage generation will be
started
according to the settings with TTL-level Low to
High
or
open
on pin 3 in case of “KILL” is disabled. If “KILL” is enabled also the push button “HV-ON” has to be
pushed.
Monitor outputs
•
Voltage monitor output
V
V-MON
= 0 to 5 V
An analogue monitor signal proportionally to the output voltage is available. This monitor voltage is
measured between pin 7 (V
V-MON
, indirect-coupled) and pin 6 (@GND, indirect-coupled).
Example: HPp 40 357, maximum output voltage = 4 kV
V
V-MON
(V)
Output voltage (kV)
5.0
corresponds to 4.0
2.5
corresponds to 2.0
1.0
corresponds to 0.8

Current monitor output
V
I-MON
= 0 to 5 V
An analogue monitor signal proportionally to the output current is available. This monitor voltage is
measured between pin 2 (V
I-MON
, indirect-coupled) and pin 6 (@GND, indirect-coupled).
Example: HPp 40 357, maximum output current = 350 mA
V
I-MON
