Preen AFV-P High Performance Programmable AC Power Source Series
The Preen AFV-P High Performance Programmable AC Power Source Series features programmable AC power sources with DC output and precision measurement. These compact power sources provide clean power with THD less than 0.3% at 50/60 Hz, and deliver an output voltage of 0-310 V, operating at a frequency of 40-500 Hz (opt. 15-1000 Hz). They are ideal for commercial, defense and aerospace test applications—from design verification to quality assurance, ATE and mass production. AFV-P series units measure rms voltage, rms current, true power, apparent power, power factor, crest factor, reactive power and more.
The AFV-P is an ideal unit for representing different real-world grid conditions, especially power adapters testing by varying frequency and voltage during manufacturing tests. The AFV-P’s output frequency can go up to 1000Hz, which is suitable to test avionic devices operating at 400Hz or 800Hz. The power line disturbance features, such as Step, Ramp, and Transient, allow the user to build a wide range of waveforms in a sequence to simulate grid faults and fluctuations, and these can also be easily configured by control software of the AFV-P.
With a total of 1200 Steps in 50 built-in Memories, users can easily use the AFV-P for testing various voltage and frequency combinations to simulate global AC power conditions, or by adding Transient feature, extreme gird fluctuations such as surges, sags, spikes and dropouts can easily be configured. With the state-of-the-art PWM technology, the AFV-P series is capable of delivering up to 4.5 times of peak current from its max. rated current, making it ideal for inrush current tests. Users can define the starting and ending phase angle from 0 to 360 degrees. The AFV-P Series’ 5" touch screen with rotary knob allows quick adjustments and configurations of voltage, current and frequency. Users can control AFV-P via standard interfaces, and free control software and LabVIEW driver are available for easy programming and remote control.
The Preen AFV-P High Performance Programmable AC Power Source Series consists of the AFV-P-600, AFV-P-1250, AFV-P-2500 and AFV-P-5000 models.
