REOhm series R 157

Max. continous power: 300 W

REOhm series R 157

Unique Selling Point


  • small dimensions
  • fast connection
  • short-circuit proof 
  • matching to any frequency converter
  • less additional mounting space required
  • very compact construction
  • high resistance in case of overload
  • vertical and horizontal design

Description


High voltage resistor for drives with frequency converters of small to medium output, installation close to the frequency converter. They are used to damp over-voltages or to dissipate excess energy that originates, for example, on braking or starting up. This is done by converting the electrical energy into heat in the resistor. 

Due to their special application, these resistors are are subject to special requirements. Highest reliability and durability combined with an extreme resistance to adverse environmental impacts are therefore absolutely necessary.
