1. Safety instructions
This High Voltage Power Supply has to be installed by skilled personnel only.
Following instructions are made for the personal safety of the operator, the safe use of this product
and the connected units.
Caution
Dangerous Voltage
This unit is supplied from line voltage of 230V and generates an output voltage of up to
30 kV.
The disregard of this voltage condition can cause death, heavy injuries or material
damage.
Danger in case of missing connector at the HV output
The LEMO-HV connector will be used for units which generate output voltages > 6kV.
It is forbidden to switch on this unit without a suitable connector inclusive a cable which
is connected to the output connector and the load.
Before connecting to the local mains it must be proofed that the nominal line voltage of this unit is
equal to the local mains.
Caution: After system-assembly the guard connections have to be checked if they are connected
correctly !
The guard connection has to be proofed through a correct mains cable. An additional guard
connection is possible via the green-yellow guard connector next to the HV Output ( ⊥/PE-connector).
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 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 > ⎪300⎪V then - in order to avoid damages for
the unit - the connections are short circuited with help of electronically protection circuits.
The unit is prepared to be mounted into a 19“-cabinet. In this case the necessary air flow conditions
through the according air input and output slots have to be guaranteed.
If the unit will be used as desk top instrument then the enclosed unit bases have to be glued on the
bottom sheet in order to guarantee a certain distance to the desk.
Before the cover of the unit will be removed the mains connection has to be disconnected, the
discharge time of at least (> 15 s) of the output capacitance has to be kept and the discharge status
has to be checked afterwards.
Only skilled and authorised people are allowed to do any service, repair or maintenance for this unit.

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
( )1x=p: positive; )1x=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 > ⎪300⎪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” (IOUT < value “Current“), the
LED “CV” is flashing.
2. Current control “CC”
Control of the output current according to the value „Current ” (VOUT < 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 IOUTmax .
Enable: The yellow LED “KILL ENABLE” is flashing.
The output voltage will be shut off permanently without ramp, if IOUT ≥IOUTmax.
The re-setting of the output voltage is possible after pushing button “HV-ON“ again.

The Standard units of the HPx)1 - 300 W and 800 W series are with CAN- and RS232-Interface.
Available as options are:
- additionally IEEE-Interface and
- indirect coupled analogue I/O with VSET/MON = 0 up to 5 V instead of RS232-Interface.
In menu “SET“ under function 09 the interface of your choice has to be selected.
If an existing interface has been selected by menu „SET“ the control of the device will be activated
automatically due to receipt of the according commands coming in ( e.g. from a PC ) and the yellow
LED is flashing.
By pushing the push button „LOCAL“ the remote control will be stopped and the device will be
switched into „HV-OFF“. In case of receipt of remote commands the device will be reactivateted
immediately.
Analogue control via analogue I/O can be selected by push button „LOCAL“ (exception see menu
„SET“, function 08), the yellow LED „REM“ is flashing. By pushing „LOCAL“ again the devices runs
back to the mode „HV-OFF“ and manual mode.
In menu “SET“ further configurations are possible. You can access the Menu by pushing button “SET“
into “OFF“ mode.
With push button “SET“ all function are available by scrolling. The desired function will be selected by
pushing “SET“ and “LOCAL“ simultaneously ⇒Function “ENTER”.
The selected values will be stored and activated by the “ENTER“ function. If this has been made
successfully the unit is back in “HV-OFF“ mode.
Pushing the button “ESC“ is going back to menu “SET“ without any change of the pre-selected
values.
Pushing button “LOCAL“ is always leading back to manual mode. In this case the HV will be shut off.
( ⇒HV-OFF).
If no push button of the menu will be switched the display is automatically going back to the mode
„HV-OFF“ after a delay time of 30 sec.

4. Description of the CAN Interface.
The integrated CAN-Interface of the HPS series offers 2 functions.
Either the interface gives access to the implemented firmware of the processor controlled unit, this is
important for the service outside and for the update of software generally
or a remote control can be established via this robust and simple industry interface for up to 64 HV
units at one serial CAN-Bus line. A Command structure similar to the CAN-Open version (CAL-based
Draft Standard 301 / Ver. 3.0) has been used.
Function of the CAN-Interface
The use of the CAN-Interface can be selected by menu “F09“ “CAn“.
As soon as the unit receives the according commands via the interface the unit is running under
remote control and the yellow LED „REM“ is flashing.
Switching the push button „LOCAL“ again the control runs back to „HV-OFF“. The receipt of
commands via interface activates the remote mode again.
The electrical transmission of all CAN-commands is indirect coupled under signal CAN_L and
CAN_H, related to CAN_GND.
The pin assignment of the D-Sub-9 connector on the rear side of the unit is written in following table.
The CAN-Bus on the first and last unit has to be connected between CAN_H and CAN_L with an
impedance of 120 Ω.
PIN 2 3 5 7
Signal CAN_L CAN_GND (GND) CAN_SHLD (shield) CAN_H
During Power ON-Reset the HPS-unit is in CAN-Status “INIT“ mode ,
afterwards it changes to CAN-Status “Operational“.
The bit rate can be selected between 20, 50, 100 and 125 kBit/s ( factory fixed 125 kBit/s ).
Only through the global command “STOP“ the CAN-Interface can be switched to CAN-Status
“Pre-operational“ .
Only in “INIT“ or “Pre-operational“ mode the access to the service of the Network-Management (NMT)
and Distribution-Management (DBT) is possible.
The global command “ADJUST“ is able to change ADC-, DAC- , SUB-Identifier and Inhibit-time in
EEPROM in the DBT.
After using “Adjust“ the global command „ADJUST“ has to be locked again.
Only in status “Operational“ the HPS unit can be controlled via CAN-Bus (read values and status, set
values).
After Power ON-Reset or after global command “START“ the interface of the unit is automatically in
status “Operational“.
