Question 396Electricity & Electronics - QMED
70% to passThe progressive operation of the contactors marked "1A" through "4A" provide the winch hoist controller shown in the illustration with what functionality? Illustration EL-0102
Aaccumulation
Bregenerative braking
Cdynamic braking
Dacceleration
AI Explanation
The correct answer is D) acceleration. The progressive operation of the contactors marked "1A" through "4A" in the winch hoist controller illustration (EL-0102) provides the functionality of acceleration. This is because these contactors are likely part of a motor control circuit that gradually engages the winch motor windings to ramp up the speed of the winch hoist, allowing for smooth and controlled acceleration. The other answer choices are incorrect because they do not accurately describe the primary function of these contactors. Accumulation (A) is not a typical winch hoist function, regenerative braking (B) and dynamic braking (C) are more related to deceleration or stopping the winch, not acceleration.
