Precision & power resistors

Our precision resistors are characterized by tight tolerances, excellent long-term stability and high temperature independence. These properties make them the ideal choice for measurement and control applications where exact measurement results are crucial, even under difficult external conditions.

In the field of power resistors, we offer solutions that are optimized for applications with high currents and high heat generation. These resistors are specially developed for use in power electronics, where thermal load capacity and high current carrying capacity are required.

Busbar shunts

Busbar shunts are common resistors for current measurement within busbars and are used for high currents that cannot be transported via a circuit board. 

They are mounted between two busbars and the voltage drop is measured via soldered-on cables, soldered-on PCBs or welded-on pins. 

The customer is free to decide how he wants to realize this voltage drop. The electrical characteristics for individual shunts can also be provided as a data matrix code if required.

Analog sensors

The analog sensors are based on the busbar shunt principle and enable a simple plug-and-play solution for the customer and their application in AC and DC, LV and HV systems.

The circuit board, including a connector, is already soldered onto the busbar shunt and both the temperature of the busbar shunt and the voltage tap can be made available to the customer in various forms via a connector. The electrical characteristic values for each shunt can also be made available via a data matrix code if required.
