AC Power Sources

Programmable AC power sources generate a controlled AC supply with adjustable voltage, frequency and waveform, so that equipment can be tested against grid conditions it will not encounter on a normal bench outlet.

Preen, Keysight, Instek, Chroma and Hioki cover this range. Output power and voltage range are the starting point, but the reason most buyers need a programmable source is the ability to simulate specific conditions: nominal voltages of other regions, frequency changes for aerospace and marine work, sags, surges and harmonic distortion for immunity testing. Check whether the unit can also sink current or regenerate, and confirm whether single-phase output is sufficient or three-phase is required. Tell us the standard you are testing against.
