December 1, 2023 - Vista, California - Axiom Test Equipment, an electronic test equipment rental and sales company has published a new blog post that covers how to find the right AC Power Supply with enough output power for each component, device, and system during testing. While precisely controlled AC electricity may not be needed when testing DUTs powered by DC power, an AC supply can help simulate real-world operating conditions.

For certain DUTs, such as electric motors, a well-controlled AC power supply can mimic the conditions in which the DUT will operate, including power supply line fluctuations, peaks, and surges. AC power supplies can be compared by electrical capabilities, such as maximum root-mean-square (RMS) voltage, maximum RMS current, maximum frequency, and maximum power in volts-amperes (VA) at a given frequency. They can also be considered by physical attributes, such as the size and weight needed to fit an application.

This is a glimpse of several AC power supplies having sufficient output power for feeding a wide range of DUTs, including electric motors. Learn more about how these supplies combine generous power capabilities by reading the full blog post on Axiom's website: https://www.axiomtest.com/blog/How-Much-Power-Is-Enough-When-Selecting-an-AC-Supply/

How Much Power Is Enough When Selecting an AC Supply 

Operating active electronic devices as part of a measurement may require an AC power source. It should be stable and dependable, but it must also provide enough voltage and current to properly operate the device under test (DUT). An earlier blog, "Essentials of DC Power Supplies and Loads," examined DC power supplies. But AC power supplies may also be needed for testing, and understanding their use can ease the task of finding one for a measurement application.

While precisely controlled AC electricity may not be needed when testing DUTs powered by DC power, an AC supply can help simulate real-world operating conditions. For certain DUTs, such as electric motors, a well-controlled AC power supply can mimic the conditions in which the DUT will operate, including power supply line fluctuations, peaks, and surges. AC power lines transfer electricity around the world, albeit at different frequencies for different regions.

AC electrical networks transfer power typically as sinewaves at a fixed frequency for one region. Europe, Africa, and Asia operate AC electrical networks at 50 Hz while the United States runs AC at 60 Hz. Japan uses both 50 and 60 Hz, for various parts of the country. AC power supplies can be selected by several specifications, such as voltage, current, and frequency. A supply can provide current across a range of AC voltages, with maximum current at a high voltage determining the highest output-power level. Power can be supplied in single-phase or three-phase form to suit the needs of a DUT and test application.

AC power supplies can be compared by electrical capabilities, such as maximum root-mean-square (RMS) voltage, maximum RMS current, maximum frequency, and maximum power in volts-amperes (VA) at a given frequency. They can also be considered by physical attributes, such as the size and weight needed to fit an application. Electrical parameters can be further defined in terms of accuracy and stability as well as resolution or how precisely a parameter, such as voltage or frequency, can be adjusted. Voltage accuracy of better than 1% is not unusual while voltage resolution of 0.5 V or better enables fine tuning. Additional consistency parameters include how closely the AC line and load are regulated, with a value of 0.2% for either parameter signifying respectable regulation for an AC power supply.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
