Chapter 6, Problem 1RQ
What is the operating voltage of most magnetic control systems?
Expert Solution & Answer
To determine
The operating voltage of a magnetic control system.
Explanation of Solution
The power supply of most industrial motors is between 240V and 480V. For use in a magnetic control system, the voltage is stepped down to 120V using a step down transformer.
Hence, the operating voltage of a magnetic control system is 120V.
