The IRM2000 metal clad wire wound resistor series from RARA offers a power rating of up to 650W in free air, with available resistance values between 2Ω and 113Ω (inductive design) or between 0.45Ω and 30.5Ω (non-inductive design). These high power resistors are available with tolerances of ±1.0%, ±5.0% and ±10.0% as standard with tab terminals, as well as inductive or non-inductive resistive windings. The IRM2000 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
Typical applications for the IRM series include:
