RARA ULH60 Series

RARA ULH60 Series

The ULH60 metal clad wire wound resistor series from RARA offers a power rating of up to 60W on a heat sink (50W in free air) with available resistance values between 0.1Ω and 400Ω (inductive design) or between 0.1Ω and 180Ω (non-inductive design). These high power resistors are available being UL approved and with tolerances of ±0.5%, ±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 ULH60 series from RARA has an extruded aluminium horizontal housing providing strong and rugged protection all with a temperature range from -55°C up to +200°C
