2. Description
The High Voltage PS of the HPx
)1
- 300 W series provide an output voltage of 0 up to 30 kV-DC at
max. 300 W output power.
The High Voltage PS of the HPx
)1
- 800 W series provide an output voltage of 0 up to 15 kV-DC at
max. 800 W output power.
Mains voltage is 85 - 264 V -AC 50/60 Hz (PFC is standard).
The output voltage and current are limited due to the hardware circuitry. The polarity is factory fixed
(
)1
x=p: positive;
)1
x=n: negative).
The shield of the HV output is always connected to the housing (
⊥
/PE-connector).
If this shield is intended to use as “reverse line“ , then a jumper has to be plugged between the “0 V“
(reverse current) and the “
⊥
/PE” connector.
If this jumper has been removed, the “0 V“ connector close to ground can be float up to max.
±
300 V.
In this case the user is responsible that - due to the voltage between “0 V“ and “
⊥
/PE“ connector - no
danger for the user may occur.
If the potential between “0 V“ and “
⊥
/PE“ connector is >

V then - in order to avoid damages for
the unit - the connections are short circuited with help of internal electronically protection circuits.
After “POWER ON“ the unit is ready to use, the displays are flashing.
The mode is “LOCAL“ now, the KILL-function is “disable“.
In “LOCAL“ mode the output voltage and the output current can be set via the 10 turn potentiometers
on the front panel. The generation of High Voltage at the HV output (on front or rear side) is starting
after pushing the button „ON/OFF“, the green LED “HV“ is flashing.
CAUTION ! The High Voltage which has been selected with help of the 10-turn potentiometer
is going to ramp with 3 kV/s to the chosen voltage, this ramp is a factory setting.
After pushing the button “ON/OFF“ again the HV will be shut OFF, the LED is off.
There are 2 control modes:
1. Voltage control “CV”:
Control of the output voltage according to the value “Voltage” (I
OUT
< value “Current“), the
LED “CV” is flashing.
2. Current control “CC”
Control of the output current according to the value „Current ” (V
OUT
< value “Voltage“), the
LED “CC” is flashing.
The KILL-function will be set with button “KILL” .
Disable: The output voltage will be limited after reaching I
OUTmax
.
Enable: The yellow LED “KILL ENABLE” is flashing.
The output voltage will be shut off permanently without ramp, if I
OUT
≥
I
OUTmax
.
The re-setting of the output voltage is possible after pushing button “HV-ON“ again.
