Characteristics :
The Edgewound Power Resistor has a finned alloy resistive element and winds around the ceramic substrate.
This design increases the overall surface area for heat convection.
This resistor is suitable for medium power and thermal energy dissipation.
Power range : 500W, 1kW, 2kW, 3kW and 4kW
Withstand short-time overload power : 10 x rated power 5 seconds
Support low resistance and high current requirement
Support multi-resistances per resistor
Support adjustable resistance requirement with an adjustable ring terminal
Support screw bolt terminals and quick fit tab terminals
Support mounting fixtures, enclosure, cooling fan and thermal switch requirement
Resistor size might change according to different resistance value and load current ratings.
