What is the advantage of inverter type power sources for PAC?

1. High power consumption

2. Large and bulky

3. Small and lightweight

4. High maintenance

The correct answer is: Small and lightweight

Inverter type power sources have the advantage of being small and lightweight, making them easier to transport and use in various environments. Option A is incorrect because inverter type power sources actually have a lower power consumption compared to other types of power sources, making them more energy efficient. Option B is also incorrect because inverter type power sources are known for their compact design, thus they are not large and bulky. Option D is incorrect because inverter type power sources are designed with fewer moving parts, leading to lower maintenance needs and costs.
