High Voltage Divider V1G

For laboratory measurement, system test point, or control loop feedback, this precision, low drift, high voltage divider provides a low voltage output from voltages as high as 25,000VDC.
The 1000:1 divider is internally compensated for your digital multimeter’s 10MΩ input impedance. Ratio tolerance is 1% and temperature drift is a low 50ppm.

The V1G divider provides a low cost solution to high voltage measurement without the expense and bulk of a probe, and without the danger of an exposed resistor. Using high voltage encapsulation techniques, the divider is protected from the problems that occur when high voltage is exposed to dust and moisture.
PCB pins and mounting holes make this module ideal for PCB mounting. The high voltage connection is made through a 30 kV silicone wire.

The PHV1000-RO is a 400MHz, standard sized, 100:1 passive probe designed for instruments having 1MΩ input resistance.
This probe is recommended for probing applications in service and development environments and is adjustable for low and high frequencies. It is also recommended for transient measurements up to 6kV such as EMC testing applications.
The probe is rated with 1000V CAT II maximum input voltage and complies with latest safety standards. The DC fine adjustment enables trimming for preferred voltage ranges.


High Voltage Passive Probe, 100MHz, 20kV DC / 40kV Pulse, 1000:1


  • CeramCoreTM Hybrid Probe
  • Coaxial design
  • Optional Read-Out
  • System Bandwidth >100MHz
  • 20kV DC incl. AC Peak
  • Up to 40kV Pulse Peak
  • Optional Cable Length up to 12m

High Voltage Probes of the PHV4002 Series are the most powerful probes for performance measurements of fast high voltage signals.
Applications include measurements of ignition voltages, glitch-detection in low-voltage and medium-voltage systems, laser technology, drive technology, large-scale operations of frequency converters and many more.
With a system bandwidth greater than 100 MHz, even fast events can be captured.


Fiber Optic Interfaces

fiber-optic-interface F422-G

An interface module to convert the electrical signal of RS-422-B for an interference free data transmission via optical fibers.
The possible link distance exceeds 500m when using 200μm glass fiber cable and 75m when using 1mm plastic fiber cable.
For RS-422-B a 8 way RJ45 connector is used and the external power supply has a 4 way RJ11 connector.
The F422-G can be configured using internal jumpers, eg. as DCE or DTE device.

fiber-optic-interface LIMO-G

An interface module to convert the electrical signal of RS232-C (V24) for an interference free data transmission via optical fibers.
The possible link distance exceeds 500m when using 200μm glass fiber cable and 75m when using 1mm plastic fiber cable.
With its low power consumption the 25-pole connector can be plugged directly into a DCE or DTE connector without an external supply.
According to the specific requirements the LIMO-G is configured using internal jumpers.
For a 9-pole connector an adapter is available.

fiber-optic-interface UN series

Fiber optic connectors for serial, asynchronous and full duplex data transfer are available for 9-pole socket connector layout.
An external power supply is not essential.
Using these connectors at both ends, you can assembly a low cost and reliable link without special tools.
