{"id":521,"count":1,"description":"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.\r\nFor 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.\r\nThe 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.

In the absence of specific specifications, the most suitable material is always used for each application.","link":"https:\/\/grupotorivac.com\/en\/categoria-producto\/rheostats-and-coiled-potentiometers\/","name":"Rheostats and coiled potentiometers","slug":"rheostats-and-coiled-potentiometers","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Rheostats and coiled potentiometers - Torivac<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/grupotorivac.com\/en\/categoria-producto\/rheostats-and-coiled-potentiometers\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Rheostats and coiled potentiometers - Torivac\" \/>\n<meta property=\"og:description\" content=\"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.
