AFX Series – Programmable AC and DC Power Source

AC or DC Test Power Re-imagined

The AFX Series is a family of high power, single, split and three phase, AC, DC and AC+DC output capable Power Sources. Available models range from 6 kVA to 90 kVA with available configurations to 150kVA. Using a modern user interface for ease of use, the AFX Series is cost effective and fully programmable for both basic frequency conversion and advanced AC power line or DC power disturbance test applications.

For questions regarding the AFX Series and or custom solutions, please contact us directly or try our live chat.


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 90 kVA and higher if needed. 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.

  • 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.
  • Maximum current ratings shown are available up to 120Vrms in AC mode and 238Vdc in DC mode. Voltage and Current follow constant power profile so higher current at lower voltage and lower current at higher voltage is available.
  • 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.
  • Cabinet weights are approximate and vary with certain available cabinet configuration options.
  • Cabinet systems above 60kVA require 400/480Vac Input service. For 208Vac input requirements (-2 versions), contact factory.
  • Models 360AFX, 390AFX and 3120AFX can be upgraded to higher power levels using Pacific’s AFX POWER FLEX upgrade program. Cabinet models 3180AFX and 3240AFX can also by upgraded to higher power levels. Contact customer service for details.

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.

Single Voltage Range with Constant Power Operation

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

Waveform Library

Up to 128 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.

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.

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.


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 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.
