This series Open Helical Coil Wound Resistor aka Open Wound Resistor has coiled resistance material and winds around the ceramic substrate.
The design increases the airflow across the coiled resistance material, stabilize resistive Coil temperature and increase the rate of energy dissipation.
Power range : 500W, 1kW, 2kW and 4kW
Suitable for both Continuous Duty and Short Pulse Energy dissipation applications
Withstand Severe short-time overload : 5 x rated Wattage 5 seconds
Support low resistance and high current requirement
Support multi-Resistances per resistor
Support adjustable resistance requirement with an adjustable ring Terminal
Support Mounting Fixtures Enclosure, Cooling Fan and Thermal Switch requirement
Resistor size might be changed according to different resistance value and load current requirement
MFPR manufactures Open Helical Coil Wound Power Resistors for wide variety of industrial applications. Different applications can have a very different resistor electrical and mechanical profile requirement.
