AC Power Sources
The AC power source is also known as a variable AC power source or a programmable AC power source. This power supply tests alternating current (AC) powered devices. For more information, see "What is an AC Power Source? (Basic Knowledge)".
AC means alternating current power that alternates between positive and negative. AC power is supplied from the power plant to the switchboards and outlets in homes, factories, and buildings. The voltage and frequency, such as 50Hz or 60Hz of the AC power supplied, varies by country and region. For a definition of AC and to learn about AC in different countries, see "AC Power Supply: Fundamentals and International Differences".
AC power source (AC power supply) products are AC to AC converters, which can supply different AC voltages and frequencies to various countries and regions. It provides stable AC power and helps with noise and momentary power loss tests. AC-powered devices connected to the power grid must be inspected for harmonics, crest factor, etc. to prevent adverse effects on the AC line. 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.
