Load and variable resistors

Electric Test Solutions

Load and variable resistors are used for continuously variable adjustment of current, ohmic resistance and power.

 

Technical specifications

  • Voltage up to 1,000 V
  • Power up to 8 kW
  • Very low temperature coefficient due to the use
    of resistor material made of CuNi 44
  • Constant ohmic resistance over large
    temperature ranges
  • Continuously variable adjustment of the resistance,
    e.g. via a motor drive
  • A stepped winding enables optimal design of the
    resistor to save space while executing high powers
    at constant voltage
  • Option: Low-inductance version due to bifilar winding
  • Option: Customised features with step circuit,
    regulation, measurement and control


Applications

  • Schools and universities
  • Drive technology
