Chapter 6, Problem 1RQ

What is the operating voltage of most magnetic control systems?

Expert Solution & Answer
Check Mark
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.
