Power Resistors
For more than 100 years Ruhstrat power resistors have been used all around the world in many electrotechnical fields. Our concept is to offer complete solutions and to be a reliable partner for our customers. We develop and manufacture power resistors for a large variety of different technical applications, in a power range from 10 W up to several 5.000 kW.
Ruhstrat is not only characterized by a broad application programme but most notably by the know-how concerning project planning of various resistor plants. According to the requirements and specifications of the respective project we dimension and manufacture the desired resistor plant.
- rated power 50 W up to 5.000 kW
