CHARGING RESISTORS

Damping and charging resistors of REOHM exist in two series:

The REOhm NTT R 150 resistors are used for example in railway engineering, electric vehicles or commercial vehicles as charging or damping resistors (even as braking resistors up to 100 kw power).
They are used to damp over-voltages or to dissipate excess energy that occurs, for example, on braking or starting up. This is done by converting the electrical energy into heat in the resistor. 
Moreover, the resistor is very well protected against mechanical loads. This ensures a long-term functional reliability.

Only railways-approved, high-quality raw materials are used for the REOhm NTT R 150 series. The connecting leads and all the other components are specially designed for the railway application. Only materials with railway approval are used.

Charging resistors of the REOhm series R 150 series are used for example in the renewable energy sector, in industrial converters or in scientific research.
