Rheostat PRN-322
Indosaw Rheostat PRN-962
Version for very high loadings. Three parallelly connected resistance coils, in a housing. Sliding pieces are mechanically and electrically connected.
The Table-Top Variable Resistor is a versatile tool for controlling DC and AC currents or voltages in electrical applications. Ideal for labs, education, and more, it functions as both a rheostat and potentiometer, offering precise, reliable performance. Built to international standards, it is essential for professionals and educators.
