RARA IRM2800 Series

Description

The IRM2800 metal clad wire wound resistor series from RARA offers a power rating of up to 750W in free air, with available resistance values between 3Ω and 135Ω (inductive design) or between 0.7Ω and 33.5Ω (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 IRM2800 series from RARA are 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
