Over 85% Energy Efficient AC & DC Power Source

The AFX Series consists of a range of High Power Switching AC, DC and AC+DC capable Power Sources covering a power range from 6 kVA to 180 kVA (1). All AFX models offer single, split and three phase output configurations. The AFX is a state-of-the-art design using the latest digital power conversion technologies. Power density is among the highest in the industry allowing 15 kVA/kW of power in only 4U (7″) of rack space.
Great emphasis has been placed on energy efficiency, ease of installation, and maximum power per cubic inch of rack space.
Control and operational features provide a high degree of application versatility and ease of use for the test engineer. Applications range from simple, manually controlled frequency conversion to harmonic immunity testing and sophisticated transient simulation.
Power conversion within the AFX Series is achieved by digitally controlled, high frequency pulse width modulation, resulting in cool, quiet and efficient operation. Some AFX models can be upgraded by customer service to provide higher power output using our POWER FLEX upgrade program.
The AFX series includes standard analog and digital I/O functions, scope function for voltage and current waveform capture, programmable output impedance and harmonic analysis measurements. Frequency range has been expanded to cover 1Hz through 3000Hz (with some power and voltage restrictions) and extended output voltage range to 333VLN / 576VLL.

Note: For requirements less than 6kVA, see LMX Series or LSX Series.

Key Features

Key Features Provide Application Versatility

Design Provides Total Control of AC and DC Power

Special AFX Series Operating Features

Continuous Self Calibration:

Provides for exceptional accuracy of the AC or DC output Voltage. When enabled, accuracy improves to ±0.02% referenced to the power source internal voltmeter.

Cycle Based Transients:

Create and execute transients that substitute a waveform in any or all phases for 1 to 100 cycles. The waveform being substituted can be selected and/or modified from the waveform library.

Time Based Transients:

Create and execute transients that occur over a specified time segment to modify the output waveform, voltage, and frequency for any or all phases. An output trigger is provided for synchronizing external test equipment to the actual transient event.

Single Voltage Range with Constant Power Operation:

More output current available at lower voltage setting without having to change range.

Waveform Library:

Up to 200 different waveforms can be stored in the waveform library for execution as part of a steady state program or for substitution in any output phase as part of a transient test program. Memory location #1 is a non-editable high resolution sine wave. Locations 2-127 are editable and can be substituted in any output phase. An unlimited number of waveforms may be stored on the computer using the available PPSC Manager Windows software.


AC or DC Test Power:

The AFX Series Power Source is equipped with several powerful Digital Signal Processors to create a fully integrated test system. It supplies a variety of power conditions to the device under test and meters all output performance parameters.

AC+DC Test Power:

Special test requirements such the application of a DC offset on an AC line or AC ripple on a DC supply output are supported by selecting the AC+DC Mode of operation.

Frequency/Voltage Conversion:

The AFX Series is an excellent source of stable AC voltage over the frequency range of 1 to 3,000 Hz. The output frequency is accurate to 0.01%.

Phase Conversion:

With the ability to provide single, split and three-phase outputs, the AFX Series is the perfect choice to provide 1 Phase to 2 or 3 Phase or 3 Phase to 1 Phase conversion.


The AFX Series controller offers both manual and full programmable control. Front panel operation is menu driven using a combination of direct access menu keys to the left of the large color display and 5 soft keys located on the right of the display. The rotary knob can be used to scroll through menu fields and doubles as an ENTER key. The same knob allows for slewing of output parameters. A full decimal keypad is provided as well for direct parameter entry. The AFX can also be operated remotely from one of its included remote interfaces. Operation from a web browser via LAN or USB is also supported through the embedded web server of the AFX.
