CAUTION!
CAUTION
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.

1 General description
WARNING!
WARNING!
The devices induce output voltages and currents which conformable to EN61010-1 are not
dangerous to life. But it is possible that they effect health damages to sensitive persons.
The iseg SHR modules are standalone High Precision HV laboratory SMU – Source Measuring Unit – equipped with the
finest iseg HV generation technology and iCS control system.
The SHR provides up to 4 channels, each with an independent voltage and current control and electronically reversible
polarity. The 6kV channel provides a maximum versatility: with three electronically switchable HV-output modes it can
supply 4mA up to voltages of 2kV, 3mA up to 4kV and 2mA up to 6kV. Alternatively the SHR can be equipped with cost
efficient 2kV/6mA channels.
A high quality 4.3” TFT display shows detailed information and can be controlled by capacitive touch. All comprehensive
features like logging, graphical display and customer specific plugins are also available by the precise jog-wheel and
buttons.

3 Handling
- to be continued -
CAUTION!
CAUTION!
The device is not designed to operate as a current sink.
Never apply external voltages of opposite polarity to the selected one or with values greater than the maximum
value of the selected output mode. This can damage the module.
4 Options
4.1 VCT – voltage correction by temperature
This option allows a temperature dependent correction of the output voltage. The temperatures are measured with a
distinct sensor for each channel. The temperature sensors are connected via BNC connectors on the backplane of the
module. An user-adjustable VCT-coefficient allows to specify a linear relationship between the measured temperature and
the output voltage. As an option one sensor per module can be orded.
4.1.1 Technical data
Sensor type EPCOS B57867S0502F140
Temperature range -40 … 80°C
Accuracy of temperature measurement ±0.5 K (0 … 60°C)
Resolution of temperature measurement 1 mK (0 … 60°C)
Temperature update rate 15 updates/min
Table 5: Technical data VCT sensor
4.1.2 Operation
The connector of the temperature sensor must be plugged in the slot of the corresponding channel on the VCT-connector
at the rear panel of the HV-module.
A programmable VCT-coefficient for each channel defines the rate and the direction of the voltage correction. The
temperatures, measured at the sensors can be read out from the module.
At the time a HV-channel is switched on or the output voltage is set by the user, the module registers the temperature of
the corresponding sensor and the set voltage as reference values.
If the temperature at the sensor changes, the output voltage is automatically adjusted according to the formula:
V = V
ref
+ a*(T-T
ref
) (a…VCT-coefficient)
Example: A channel is set to 60V. At the time it is switched on a temperature of 25°C is measured. The VCT-coefficient is
set to +1V/K. If the temperature now increases to 26°C the output voltage will increase to 61V. (For channels with a
negative output voltage the voltage changes from –60V to –61V).
A VCT-coefficient of -1V/K would decrease the voltage to 59V.
SHR – Desktop High Voltage Power Supply | Last changed on: 19.01.2018 | www.iseg-hv.com 7/11
Notes:
• During operation the values for Vset are adjusted. If a channel is switched off the adjusted set value will be kept, not the
original value set by the user.
• If the VCT-coefficient if modified during operation, Vref and Tref are reset to the present values to prevent a sudden
voltage change.
• If the temperature sensor is dis- and reconnected during operation, Vref and Tref are reset to the present values to
prevent a sudden voltage change.
• The temperature dependent voltage correction can be deactivated by setting the VCT-coefficient to 0 or by
disconnecting the temperature sensor. If this is done during operation, the channel will keep the actual voltage set.
• If the temperature sensor is disconnected a temperature of -273.15°C is shown for that channel.
• The VCT data points are described in the manual "iseg Hardware Abstraction Layer" (see appendix).
4.2 Single Channel Inhibit
INFORMATION
INFORMATION
INHIBIT is an external signal, that switches off the high voltage for the device or a specific channel
If none of the options IHB, IHD or VCT is ordered, modules are equipped with an INHIBIT for each channel via a Sub-D
connector on the backplane of the module. Channel 0 to 3 corresponds to Pin 1 to 4 at the Sub-D connector, Pins 5-9 are
connected to GND.
With option IHB the module is equipped with BNC connectors for the INHIBIT of each channel instead.
The INHIBIT signal are TTL-level, the signal logic and default states can be configured. The following settings are possible:
Case 1 – IU
INHIBIT signal logic: LOW-active (LOW HV-generation stopped)→
default state: HIGH (internal pull-up resistor applied)
open INHIBIT signal input: HV enabled
Case 2 – ID
INHIBIT signal logic: LOW-active (LOW HV-generation stopped)→
default state: LOW (internal pull-down resistor applied)
open INHIBIT signal input: HV disabled
Case 3 – NIU
INHIBIT signal logic: HIGH-active (HIGH HV-generation stopped)→
default state: HIGH (internal pull-up resistor applied)
open INHIBIT signal input: HV disabled
Case 4 – NID
INHIBIT signal logic: HIGH-active (HIGH HV-generation stopped)→
default state: LOW (internal pull-down resistor applied)
open INHIBIT signal input: HV enabled
SHR – Desktop High Voltage Power Supply | Last changed on: 19.01.2018 | www.iseg-hv.com 8/11
The INHIBIT signal must be applied for at least 100 ms to guarantee a detection. When the INHIBIT is no longer active, the
INHIBIT flag must be reset before the voltage can be switched ON again.
4.3 IHD - Detector INHIBIT
The option IHD is a special version of a single channel INHIBIT to be connected to the HV INHIBIT outputs of
detectors/preamplifiers from Ortec and Canberra. In order to enable the HV generation either a positive voltage signal
(Canberra) or a negative signal (ORTEC) must be applied. The INHIBIT signals are connected via BNC connector (one for
each channel) located on the backplane of the module.
4.4 L – Lower output current (HP only)
The output current is limited to a lower value, e.g. 100 µA.
4.5 T10 – Lower temperature coefficient (HP only)
Improved temperature coefficient of 10ppm/K
