RARA ULM1600 Series

RARA ULM1600 Series

The ULM1600 metal clad wire wound resistor series from RARA offers a power rating of up to 570W in free air, with available resistance values between 1.5Ω and 88Ω (inductive design) or between 0.3Ω and 23Ω (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 ULM1600 series from RARA are UL approved 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
