2.3 General Overview
The Surface Concept 19” HVPS-HC Module R012 is a high voltage module especially designed for the
Surface Concept 19”Basic Unit, a modular supply system.
The 19”HVPS-HC Module R012 comes as a 1 channel/ 2 channel version, which provides one/two separate
high voltages with a switchable polarity (must be manually switched by the user). It also provides the
capability to oat on a reference potential. Hereby each channel has its own, individual reference input. For
the 2 channel version, the both channels work absolutely independent on reference potential and output
polarity.
Depending on the maximum output voltage the 19” HVPS-HC Module R012 comes with either SHV
connectors (maximum output voltage <= 5kV) or with 10kV LEMO connectors type ERA.1S.405.CTL
(maximum output voltage > 5kV).
The device can produce lethal high voltages of up to several kV. Hazardous voltages are
present, therefore only persons with the appropriate training are allowed to carry out
the installation, adjustment and repair work.
Do not open the power supply, while it is in operation. Hazardous voltages are present.
In case that the device must be opened, turn o the device rst AND pull out the power
plug.
Note
The 19” HVPS-HC Module R012 is available with dierent output voltages and dierent
maximum oating voltages. Check the specication sheet of your specic 19” HVPS-HC
Module R012 for detailed information on those parameters.

3 Introduction
3.1 Initial Inspection
Visual inspection of the system is required to ensure that no damage has occurred during shipping. If
there are any signs of damage, please contact SURFACE CONCEPT immediately. Please check the delivery
according to the packing list (see Table 1) for completeness.
• 1x 19“ HVPS-HV Module R012
• 1x Termination Plug (SHV or LEMO 1S) per channel
Table1: Packing list for the 19“ HVPS-HC Module R012.
3.2 Installation
The general connection scheme of the 19”HVPS-HC Module R012 is as follows:
Figure 1: Exemplary basic connection scheme of a 2 channel Module R012 with SHV connectors.

819“ HVPS-HC Module R012 Manual | Surface Concept GmbH
The 19” HVPS-HC Module R012 is specied for the operation with an external reference
voltage. Please check the specication sheet of your specic module for the maximum
allowed reference voltage.
All 19” HVPS-HC Module R012 with a maximum output voltage <= 5kV come with SHV
connectors, independent on their maximum oating voltage.
Therefore it must be taken care o, that the sum of the module output voltage and the
applied oating voltage is not exceeding 5kV in total.
In cases that no reference voltage is applied to the device, the termination plug must
be used to ground the reference input of the 19” HVPS-HC Module R012. With a missing
reference potential the device is not providing any output voltage.
Finish the complete cabling of the 19”HVPS-HC Module R012 before switching on the 19”
Basic Unit and switch o the device rst before performing any changes to the cabling.
• Install the 19” HVPS-HC Module R012 into a free slot of the 19”Basic Unit (if not already installed).
• Use appropriate cables (SHV or LEMO 1S) to connect the outputs with the corresponding polarity
suitable for your application.
• Use the termination plugs (SHV or LEMO 1S) to terminate the output with the opposite polarity to GND
(e.g. terminate the negative output of channel 1 in case that the positive output of channel 1 should
be used).
• Alternatively an external reference potential can be applied instead of using the termination plug for
a termination to GND.

4.2 General Device Operation
After switching on the 19” Basic Unit, the display shows the “Surface Concept” animated logo, while the
device is scanning for the 19” HVPS-HC Module R012 and its specic settings. This can take up to several
seconds. If the 19”Basic Unit is ready for operation, it switches into the standby mode and shows an empty
mask for the voltage adjustment (see Figure 3).
Push the“Start/Standby” button in the lower left
corner of the display to switch on the high
voltage.
Alternatively one can press the“Channel”control
knob.
After switching on the high voltage the device
is in the so called operation mode. In operation
mode the display shows the name of the selected
channel in the top line (in this case“HV 1”) as well
as the output voltage of that channel.
The dierent HV channels can be selected by
turning the “Channel” control knob.
Figure 3: Standby mode.
Figure 4: Operation mode.
Figure 5: Operation mode – voltage adjustment.
The “Adjust” control knob is used to adjust
the output voltage. Turn the “Adjust” control
knob clockwise/counter-clockwise to increase/
decrease the value of the output voltage in a step
width as dened in the line “edit step”.
The line “set value” displays the nominal value
for the output voltage as adjusted by the user.
Voltage adjustment can only be made in this line.

11
Manual 19“ HVPS-HC Module
19“ HVPS-HC Module R012 Manual | Surface Concept GmbH
The line “actual” displays the actual value for the output voltage on the output connector as measured by
the device. The device always regulates the actual value of the output voltage to t to the nominal value
as set by the user. Hereby the voltage measurement is always a relative measurement between the two
HV outputs of one channel. Additional reference voltages (e.g. in oating operation) are not measured
and therefore are also not displayed (see the manual of the specic module for further details). Turn the
“Adjust” control knob clockwise/counter-clockwise while pushing it to increase/decrease the step width
in the line “edit step”.
Push the„Start/Standby“-button in the lower left corner of the display again to switch back to the“Standby”
mode.
4.3 Schematic Layout of the 19” HVPS-HC Module R012
Figure 6 shows the schematic layout of the 19” HVPS-HC Module R012 and especially the layout of the HV
outputs. An internal controller measures the output voltage and regulates it to the nominal value entered
by the user or set as default value within the device. Hereby the voltage measurement is always a relative
measurement. The output polarity is xed dened (see the specic specication sheet for details on the
max. output voltage and the polarity). Figure 6 also shows the internal load and measuring resistors.

12 19“ HVPS-HC Module R012 Manual | Surface Concept GmbH
when a HV module with oating capability is stacked on top of a reference voltage, then it can happen that
the oating,“upper” HV module “pulls up” the reference voltage of the “lower” reference HV module when
operating. This “pulling up” eect is caused by cross current ows from the one to the other HV module
and it depends on the output voltage of the oating HV module in respect to the output voltage of the
reference HV module as well as on the internal resistances to ground within the dierent modules and on
the polarity of the output voltages of the both HV modules (e.g. the“pulling up”eect is much stronger for
dierent polarities between the both modules then when both polarities are the same).
4.4 Floating Operation
For the 2 channel version of the 19” HVPS-HC Module R012, one can not only use external HV supplies
to provide a reference voltage, but also one of the both channels of the R012 can be used as reference
potential for the other HV channel.
The connection scheme of one HV channel of the 19” HVPS-HC Module R012 in oating operation in
reference to the second HV channel is shown in Figure 7.

channel.

Manual 19“ HVPS-HC Module
19“ HVPS-HC Module R012 Manual | Surface Concept GmbH
This eect occurs independent on using an external HV module or using the second HV channel of the
R012.
This “pulling up” eect can be minimized by installing an addition resistance to ground on the HV output
of the reference HV module, to create an additional current ow out of the reference HV module.The value
of the resistance depends on the necessary current ow, which should be larger than the current ow out
of the oating HV module (a typical resistance values for the oating operation of MCP based detectors is
10MOhms).
External resistances in a compact housing with SHV connectors are available from Surface Concept to
connect in between the HV line of the reference HV module.
The connection scheme of the 19”HVPS-HC Module R012 in oating operation with such external resistance
is given in Figure 8.
Figure 8: Connection example for the oating operation of HV
channel 2 with positive polarity in reference to the negative
output of HV channel 1 with an external resistance to ground
connected to minimise the“pulling up”eect.
