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.

Newly available A Version offers extended voltage and frequency ranges and new analog and digital I/O functions.

3150AFX 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 90 kVA and higher if needed. All AFX models offer singlesplit 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 new for 2018 A versions of the AFX now include 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.

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 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.

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.

  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 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.
  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. Cabinet systems above 60kVA require 400/480Vac Input service. For 208Vac input requirements (-2 versions), contact factory.
  4. Cabinet weights are approximate and vary with certain available cabinet configuration options.
  5. 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 us for details.
