Programmable AC/DC Output Power Source

Intepro’s AFV-P Series is a programmable AC/DC output power source with precision measurement and control. This compact power source comes in four power levels, 600VA, 1250VA, 2500VA and 5000VA, providing clean power with distortion less than 0.3% at 40-100Hz. The AFV-P series delivers output voltage from 0 to 310VAC and frequency from 40 to 500Hz or 15 to 1000Hz with the high frequency option. It is ideal for commercial, defense and aerospace test applications from design verification, quality assurance, ATEs. The AFV-P Graphical Users Interface software makes it easy to setup complex testing of the AC input to the UUT.

The internal memory stores up to 1200 transients in 50 registers. Transient generation functions provide simulation of voltage variations, surges, drops and frequency disturbances. With the state-of-the-art PWM technology, the AFV-P series is capable of delivering up to 4.5 times of peak current (crest factor) from its max rated current that makes it ideal for switching power supply test. User defined Start and End phase angle is available from 0 to 360 degrees.

The AFV-P series measurement features include rms voltage, rms current, true power, apparent power, power factor, crest factor and reactive power. Its 5” touch screen with rotary knob allows quick adjustments and configurations of voltage, current, and frequency. Users can remotely control the AC source via standard interfaces of USB, RS232/RS485, LAN or optional GPIB and analog control. Free control software and LabVIEW driver are available for easy programming and remote control.

Sweep & Ramp Test

The AFV-P Series offers an easy and convenient method to execute a single step or continuous output
changes. The sweep function is ideal for voltage and frequency variation tests. The response time of voltage
and frequency changes are within one cycle. Users can also use the ramp function to adjust slew rate of
voltage and frequency changes. The ramp function can also effectively reduce the inrush current during motor
startup. There are up to 50 memory locations can be run sequentially to sequence 1200 steps as each memory
location has 24 steps for the user to set up.

Transient Generation


Transient generation is an extended feature that provides the users an easy setup for power line disturbance simulation. Common waveform disturbances such as surge, sag, spikes, and dropouts can be generated for applications like immunity test.

Start/End Angle & High Peak Current for Inrush Current

90° Start Angle

In rush Current for 90° Start Angle

90° End Angle

AFV-P Series is capable of providing high output peak current (max. 4.5 peak/rms), and this feature makes it ideal to handle inrush currents required for motor testing.

Control Software

AFV-P Series provides control software and a LabVIEW driver that allows users to easily setup remote control for the power source without further need of programming.

Fast Slew Rate

For tests like sags, surges, dropouts, or spikes, slew rate is a critical factor. AFV-P Series is a high performance AC source that has a high slew rate of less than 300μs from 0~90% output voltage. It allows users to do pre-compliance tests such as IEC-61000-4-11 or MIL-STD-704F.
