It can be used to change the current and voltage in the electrical mechanical design stage and replace the variable resistor of the undetermined resistance value. It can also be used as the current and voltage regulator for research test or teaching demonstration in the laboratory, as well as the excitation and speed regulation of power generation equipment and DC motor It #39;s used to block and so on. This product adopts Kangtong wire after oxidation and insulation treatment, which is tightly wound on the porcelain tube and fixed on the metal protection bracket. Through the conductive brush of the contact system, it moves on the surface of Kangtong wire to change the resistance value. Its main features are as follows 1. High quality black constantan material, traditional technology, strong reliability. 2. Under continuous working condition, the temperature drift is small. 3. The resistance / current can be adjusted continuously with high precision. 4. The internal structure layout is reasonable, and the operation is simple and practical. 5. Through the method of series and parallel connecti
