Basic Information
It is strongly recommended to read the operator’s manual before operation.
To avoid injury of users it is not allowed to open the unit. There are no parts which can be maintained by users inside of the
unit. Opening the unit will void the warranty.
The mains connector is equipped with basic insulation and a protective earth conductor. The unit may only be operated with
protective earth conductor connected.
We decline all responsibility for damages and injuries caused by an improper use of the module. It is strongly recommended
to read the operators manual before operation.
The information in this manual is subject to change without notice. We take no responsibility for any error in the document.
We reserve the right to make changes in the product design without reservation and without notification to the users.
Violation of guidelines marked with „Warnin g “ can lead to death or severe injury
Violation of guidelines marked with „Attention!“ can lead to damages of the unit or the application

1 Safety notes
To avoid injury of users it is not allowed to open the unit. Before any operations on the HV output
or the application, the unit has to be switched off and discharge of residual voltage has to be
finished. Depending on application residiual voltages can be present for long time periods. These
residiual voltages can lead to severe injuries.
Only accessories which meet the manufacturer’s specifications shall be used. If the equipment is used in a manner not
specified by this manual, the protection provided by the equipment may be impaired. We decline all responsibility for
damages and injuries caused by an improper use of the module.

2 General information
2.1 Short description
The modules of the series SHQ are desk top high voltage power supplies which offer output voltages up to 6 kV for the use
in industry and research.
Main Characteristics:
• High voltage power supplies with front-panel operation and remote control via serial interface
• Output voltages with very low ripple and noise
• Compact housing with one or two independent high voltage sources
• Polarity is manually switchable with switches on the rear side of the housing
• Simultaneous display of current and voltage in a High Resolution format on the 2-line LCD
• Output short circuit and overload protection
