Rheostats and coiled potentiometers

Rheostats and coiled potentiometers

Potentiometers and rheostats manufactured by Torivac are essential components for precise voltage and current regulation in electrical and industrial systems, either through parallel or series connections. Our range of potentiometers, available in 3 and 5 W versions, is distinguished by their compact design, excellent linearity, smooth actuation and high precision, ensuring reliable operation and long life even in demanding applications.
For ceramic rheostats, Torivac offers high heat dissipation solutions, manufactured from 12 W up to higher powers in assembled, single-phase, double or triple configurations. The indicated power ratings are valid under adequate ventilation conditions; in environments with limited ventilation, a reduction of up to 20 % is recommended to avoid overheating and ensure optimum performance.
The resistive core consists of a ceramic ring of steatite or alumina of high hardness and anti-hygroscopic character, which eliminates the risk of corrosion by electrolysis. Top quality resistive wires -constantan, nichrome or kanthal- are wound on this core, selected according to the ohmic value and the power required. In the absence of specific specifications, the most suitable material is always used for each application.
