AC Power Sources
An AC power source, also known as a variable or programmable AC power source, is a versatile instrument used for testing devices powered by alternating current (AC). For more information, see "What is an AC Power Source? (Basic Knowledge)".
AC (Alternating Current) is a form of electrical power that periodically reverses its direction, alternating between positive and negative values. The voltage and frequency (e.g., 50Hz or 60Hz) of this AC power vary depending on the country and region. For a definition of AC and to learn about AC in different countries, see "AC Power Supply: Fundamentals and International Differences".
Our AC power sources are advanced AC-to-AC converters capable of supplying a wide range of voltages and frequencies, simulating the power conditions of different countries and regions. They provide highly stable AC power, making them ideal for conducting critical tests such as noise immunity and momentary power loss simulations. To prevent adverse effects on the power grid, AC-powered devices must be tested for key characteristics such as harmonic distortion and crest factor. For information on crest factor, which indicates the quality of the AC power source, please see "What is crest factor?".
Matsusada Precision provides single-phase and three-phase benchtop and rackmount AC power sources to help you test a wide variety of AC-powered devices.
