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 fit 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 floating operation) are not measured
and therefore are also not displayed (see the manual of the specific 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 fixed defined (see the specific specification sheet for details on the
max. output voltage and the polarity). Figure 6 also shows the internal load and measuring resistors.
