An AC power supply, or AC power source, provides electric power for an electric load. it can be programmed to vary the voltage, phase and frequency of the current that is running to a device or a system. It is an essential tool for the measurement of current in every electrical system. Actually it limits the current drawn by a load to desired levels, shuts off a current in an electrical fault and stores energy for emergency use.

Usually all Ac power supply have one input connection, which receives current from a source, and one or more power output connections to transfer current to the load.

They are used in a variety of fields for test and measurement. especially those which are related to the alternative energy, automotive, aerospace, power grid and telecommunications industries as well as for R&D testing.

These reliable AC power supplies from GW INSTEK are ideal for general electronic field service, laboratory testing, and many other applications.
