Exam Prep Questions

Question 1 What are the typical voltage outputs for low-voltage power supplies that convert household AC power into DC voltages?
  • A. 6v–24v DC

  • B. 30v–60v DC

  • C. 25v–45v DC

  • D. 3v–12v DC

A1: The correct answer is D. The standard low voltages for powering home automation systems are normally in the range of 3v–12v. Answer A is incorrect because 6v–24v is above the typical voltage range for most home, general-purpose DC power supplies. Answer B is incorrect because 30v–60v is not a voltage range used in household power supplies. Answer C is also incorrect because 25v–45v is not a typical range used in power supplies for home devices referenced in this chapter.
