    The AFX Series consists of a range of High Power Switching AC, DC and AC+DC capable Power Sources covering a power range from 9 kVA to 60 kVA. 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.

    1. All AFX models have a single voltage range with constant power profile. This eliminates the need for switching between a high and a low voltage range. If desired, a low voltage range can be simulated.
    2. Maximum current ratings shown are available at 120Vrms in AC mode and 170Vdc in DC mode. Voltage and Current follow constant power profile so higher current at lower voltage and higher current at lower voltage is available.
    3. Three phase input: -2 Models: 208 to 240 VAC ±10% input range. -4 Models: 380 to 480 VAC ± 10% input range. All models has active power factor corrected AC inputs.
    4. Cabinet weights are approximate and vary with certain available cabinet configuration options.

  • Applications

    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.
    AD+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 15 to 1,200 Hz. The output frequency is accurate to 0.01%. 

    Phase Conversion
    With the ability to provide singe, 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.
