Ribwound Resistors

Ribwound Resistors

 (863)

C&H Technology has partnered with Vishay Milwaukee Resistor to provide a wide variety of stock and custom high power resistors for the industrial market. Ribwound resistors are useful where high energy is to be dissipated in the lower ohmic ranges. Fixed and adjustable Ribwound resistors are available from 40 to 2000 watts to meet your customer requirements. Ribwounds are smaller than the equivalently rated roundwire resistors providing significant savings in space and cost. 300, 500, 1000, 1500 watt are in stock in commom ohmic values.

Common Applications: Alternative Energy and Power Management: Overhead Cranes, Elevators, Lift Trucks, Machine ...

RoundwireFixed

Roundwire Resistors

 (460)
C&H Technology has partnered with Vishay Milwaukee Resistor to provide a wide variety of custom high power resistors for the industrial market. Resistance wire is spotwelded to the terminal bands and then locked onto the core with a vitreous enamel or silicon coating. Fixed and adjustable roundwire resistors are available from 8 to 1150 watts to meet your customer requirements. Special coatings, temperature coefficients, tolerances and non-inductive windings can be specified for any custom requirement.

Oval

Oval Resistors

 (68)

C&H Technology has partnered with Vishay Milwaukee Resistor to provide a wide variety of stock and custom high power resistors for the industrial market. Terminal bands are spotwelded onto the insulated core and resistance-alloy wire is precisely wound onto the oval core. The wire is then spotwelded onto the terminal bands and "locked" onto the core with silicone or cement coating. Available with fixed or adjustable resistance.

Common Applications:
Alternative Energy and Power Management: Overhead Cranes, Elevators, Lift Trucks, Machine Tools, Industrial Controls, Conveyors, UPS Systems, Motor Braking Resistor, Battery Load Testing, Wind Turbine ...
