Question 359Electricity & Electronics - QMED
70% to passIf the supply voltage is 220 volts 60 Hz, what is the operating voltage of the motor controller control circuit illustrated in figure “A” of the illustration? Illustration EL-0011
A110 volts DC
B110 volts AC
C220 volts DC
D220 volts AC
AI Explanation
The correct answer is D) 220 volts AC. When the supply voltage is 220 volts 60 Hz, the operating voltage of the motor controller control circuit illustrated in figure "A" of the illustration EL-0011 will be 220 volts AC. This is because the control circuit is designed to operate directly on the same supply voltage as the main power source, which in this case is 220 volts AC. The other options are incorrect because a motor controller control circuit would not use 110 volts DC (A) or 110 volts AC (B) when the supply voltage is 220 volts 60 Hz, and 220 volts DC (C) is not a standard voltage for this type of application.
