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 85 to 260 V-AC 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 con-

nected 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 an additional “reverse line“ from the load to the “0 V“ connector must
been used and this 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 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.

3 Functional 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.

The control loop is designed to provide a constant voltag or current.

The High Voltage PS of the LPx)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 LPx)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 control loop is designed to charge a capacity in constant current control mode. This capacity will
discharge with the user circuit. You will find information to the discharge frequency dependence on
the discharge level in chapter 2.

On LPS devices, the Software voltage ramp (0…3000V/s) can be disabled. The device then ramps to
the choosen set voltages as fast as possible (see chapter 4 “Front panel operation” and 6 “Command
sets”).

Mains voltage is 85 to 260 V-AC 50/60 Hz.

The output voltage and current are limited due to the hardware circuitry. The polarity is factory fixed

)1

(

x=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 an additional “reverse line“ from the load to the “0 V“ connector must
been used and this connector close to ground can be float up to max. ± 300 V.

Attention: 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.

3.1 Operation states

The device has the following operation states:

- POWER-ON Device initialises the connected Hardware (Booting)

- LOCAL Device is controlled with buttons and rotary encoders at the front panel

- REMOTE Device is remote controlled via interface (CAN, RS-232, IEEE-488)

The states LOCAL and REMOTE are further divided into:

- HV-OFF No high voltage is produced

- HV-ON High voltage according to Set values is produced

In the HV-ON state there are two modes for high voltage creation:

1. Voltage control CV:
Control of output voltage according to set value V
(Output current I

OUT

< I

), LED „CV“ lighting.

SET

2. Current control CC (only with “Kill disable”):
Control of output current according to set value I
(Output current V

OUT

< V

), LED „CC“ lighting.

SET

The KILL function is be set with the KILL/ESC button:

Disable: The output voltage will be limited after reaching I

Enable: The yellow LED „KILL ENABLE” is lighting.

The output voltage will be shut off permanently without ramp, if I
The re-setting of the output voltage is possible after pushing button HV ON again.

3.2 Safety loop (Interlock)

The unit is equipped with a connector for a hardware safety loop (interlock) on the rear.

If the loop is closed an internal current source (open circuit voltage 15 V / short circuit current max.
40 mA) will drive a current of ca. 12 mA through the built-in safety relay.

That will work if the impedance of the closed loop is less than 200 Ohm.

If the safety loop is opened, the relay will be drop-out and the generation of high voltage will be
stopped without any semiconductor by the contacts of the safety relay only.

Caution: The internal and external capacities must be discharge about the load before the

output will be volt-free. The internal load is very high, so a very long discharging
time is possible according to the connected load.
The unit is not equipped with an active discharging circuit!

The safety loop is closed ex works with help of a wire strap.

It is not possible to switch on the high voltage generation if the loop is open.

If the loop will be closed again high voltage will be switch on with HV-ON on front panel or via the
digital interfaces only.
If chosen AIF ON in the menu F06 „Control with analogue I/O automatically“ it is able to switch
on high voltage with Low to High on the INHIBIT pin of the analogue I/O too.

By pressing ON/OFF again, the high voltage generation is turned off, the green LED “HV” goes off.
The high voltage is ramped down with the programmed ramp speed.

4.1 Displays

The device has two eight digit displays for voltage and current as well as for Menu control.

In HV-OFF state, the set values are shown on display for easy changes with the rotary encoders
VOLTAGE and CURRENT. These set values are stored in processor’s EEPROM and reloaded at
next start-up.

While displaying the set values for voltage and current, a small ’s’ is flashing at the left display side:

s1.000kV s800.0mA

Picture: Set values on display in HV-OFF state

In HV-ON state the measured values of voltage and current are displayed:

0.995kV 752.3mA

Picture: Measured values on displays in HV-ON state

By pressing the rotary encoder VOLTAGE or CURRENT in HV-ON state, the corresponding set value
is displayed for a short time to allow exact adjustment.

If the set values aren’t changed, the device shows the measured values again after four seconds. By
pressing the corresponding rotary encoder again, this delay can be shortened.

After turning high voltage off, the displays show the measured values while ramping down. After four
seconds an with measured voltage lower than 60 V, the device shows the set values again.

4.2 Menu

In HV-OFF mode the device menu is activated by pressing the button MENU.

If no button is pressed, the display switch back to HV-OFF mode after 30 seconds. The menu can
also be closed without changing any value by pressing the button ESC.

By turning the rotary encoder VOLTAGE you can scroll through the menu. By pressing the rotary en­coder VOLTAGE the displayed menu point is selected. The setting can be changed by the active ro­tary encoder (shown by yellow LED). By pressing the active rotary encoder the changes are stored
and the main menu is displayed again.
