rotary rheostat / manual / wire-wound / power
Rotary rheostats are useful when you need to achieve a full-scale variation within one full turn at current ratings ranging between 16 and 300 watts. For high ratings, several units can be assembled. Within the range of feasible values, each rheostat is built at the necessary ohmic value. These products have been offered by Coudoint for decades and have proven their durability and quality over and over again.
In order to ensure the best stability of the ohmic value, the windings are constructed from low-temperature coefficient resistance wire. The slider mechanisms are designed to ensure a high resistance to wear (durability) and for smooth operation. Multiple options like the housing, manual or motorized slider drives and various terminal connections add to its usefulness.
