An AC Power Source, also known as an AC Power Supply is a device that is capable of supplying variable power and frequency to a load. An AC power source<\/a> supplies an alternating electrical current that helps power or test a separate piece of equipment by simulating electrical grid interruptions, harmonics, surges, or other events that could cause a device under test (DUT) to malfunction.  AC Power sources such as the IT7321 AC Power source<\/a> units are commonly used for electrical testing in aviation, lighting, laboratory testing, military and factory production.  This AC Power Source allows you to generate signals of alternating current from 45Hz up to 500Hz. It can also generate different forms of a sine wave including surges, traps, and dimmed phase waves for simulating different events.<\/p>\n\n\n\n

AC power has the shape of a sine wave.  On the graph above the amplitude is voltage in volts and the frequency would be measured in periods\/second.  In North America the residential electrical grid is most commonly 1 phase 60 Hz 120VAC<\/a>. In Europe, the grid operates at 50Hz and 230VAC<\/a>. <\/p>\n\n\n\n

This model uses precision linear amplification<\/a>. Linearity describes how supply has the ability to produce signals that are accurate copies of the input at varying power and frequency levels.\u00a0In avionics, there are stringent testing requirements, electronics equipment designed for aviation and operation at 400 Hz AC will require testing to demonstrate compliance. An AC power source such as the IT7321 allows you to perform these tests accurately and easily.
