The IRM800 metal clad wire wound resistor series from RARA offers a power rating of up to 800W on a heat sink (360W in free air) with available resistance values between 0.1Ω and 112Ω (inductive design) or between 0.1Ω and 28.8Ω (non-inductive design). These high power resistors are available with tolerances of ±1.0%, ±2.0%, ±5.0% and ±10.0% as standard with other options available including flying leads or tab terminals, as well as inductive or non-inductive resistive windings. The IRM800 series from RARA are a metal cover type with an extruded aluminium housing providing strong and rugged protection all with a temperature range from -55°C up to +200°C

  • Metal clad wire wound resistor
  • Option of flying leads, parallel or series terminal connections
  • Inductive resistance ranges available between 0.1Ω and 112Ω (flying leads), 0.1Ω and 11Ω (parallel tab terminal connection) or 11.1Ω and 112Ω (serial tab terminal connection)
  • Non-inductive resistance ranges available between 0.1Ω and 28.8Ω (flying leads), 0.1Ω and 7.2Ω (parallel terminal connection) or 7.3Ω and 28.8Ω (serial terminal connection)
  • TCR of +260 ppm/°C maximum
  • Tolerance values available of ±1.0%, ±2.0%, ±5.0% and ±10.0%
  • Power rating of 800W on a heat sink (360W in free air)
  • Metal cover type with an extruded aluminium housing
  • Insulation resistance of 20MΩ minimum
  • Temperature range between -55°C and +200°C
  • Short time overload of 10 x power rating for 5 seconds

 

Typical applications for the IRM series include:

  • Motor drives
  • braking and snubbing applications
  • Power sources for industrial equipment
