The Ohmite RRS1K5 wirewound rheostat is a precision electro-mechanical device used for variable resistance in industrial control systems. Its wirewound construction ensures high power handling capabilities and excellent stability. Typical applications include motor speed control, volume adjustment in audio equipment, and laboratory experimentation. Due to its mechanical nature, the rheostat has a finite lifespan and requires periodic maintenance. Models H, J, G, K, L and RRS are suitable for a wide range of applications requiring adjustable resistance.
