AC Test Power Re-imagined
The ADF Series is a family of high power, single or three phase, AC Power Sources. Available models ranging from 15 kVA to 90 kVA. Using a modern user interface for ease of use, the ADF Series is cost effective and fully programmable for many frequency conversion test applications.
Standard output frequency range is from 45 Hz to 500 Hz, covering all commercial and industrial power frequencies as well as typical 400 Hz avionics testing. The available F option offers frequency range extension down to 15 Hz for railway applications and up to 800 Hz for wild frequency avionics applications. For DC test applications, DC output mode can be added as an option (option D)
Looking for a power source that also supports AC+DC output, arbitrary waveforms and extensive transient programming? Check out the AFX Series, also from Pacific Power Source.

Single Voltage Range with Constant Power Profile
Traditional AC power sources use two voltage ranges to provide either high voltage or high current. By contrast, the ADF Series uses a unique single voltage range that operates along a constant power curve. This provides more current at low voltages, eliminating the need to switch between voltage ranges and provides a much wider operating range (demonstrated as green in the figure below).
Switching voltage ranges on other AC sources causes the output to be turned off and the EUT to shut down. This makes it difficult to test universal wide input range AC products.
The blue line and green shaded area in the chart shows the additional operating range available compared to a conventional AC power source with a 150V/300V range pair.
