The Preen AFV-P series is a programmable AC power source with DC output and precision measurement. This compact power source provides clean power with THD less than 0.3% at 5-100Hz, and it delivers output voltage of 0-310V and frequency of 15-1000Hz (opt. 5-2000Hz). It is ideal for commercial, defense and aerospace test applications from design verification, quality assurance, ATE to mass production.

The Preen AFV-P series comprises measurement features of rms voltage, rms current, true power, apparent power, power factor, crest factor, reactive power etc. The 5in touch screen with rotary knob allows quick adjustments and configurations of voltage, current and frequency. A total of 1200 test steps in 50 built-in memories and transient generation functions allow simulations of voltage variations, surges, drops and frequency disturbances. Users can set start and end phase angle from 0 to 359 degrees, and remotely control AFV-P series via standard interfaces. Free control software and LabVIEW driver are available for easy programming and remote control.

Through the Transient feature, user can have more control over the waveform by inserting disturbance at user-defined locations with user-defined drop/rise range. This is a useful feature to simulate different pre-compliance tests and various types of power line disturbance, such as surge, sag, spike and dropout, for immunity tests.

For switching supply (rectified load), AFV-P series provides standard inrush current as 4.5 times of max. output current and the AFV-P-600 and AFV-P-1250 have optional 9 times of max. output current, which makes AFV-P series the lowest capacity in the market that can achieve the highest inrush current. Also, the AFV-P series allows users to set the start angle/end angle for the product output, which is suitable for testing switching power supplies.

To create a complex sequence on the HMI is no longer a difficult task for AFV-P series. The 5in touch screen provides users with a clear display and an easy set up. The AFV-P series can display 4 shortcuts of Memory Sets, and the voltage and frequency setting of each Memory Sets can be clearly read. The user can quickly switch the output by selecting the shortcuts.

The AFV-P series is equipped with communication interfaces of USB, Ethernet, RS232, and RS485, so users no longer need to spend extra on remote interface card. Only GPIB and Analog are optional interfaces. The AFV-P series also provides control software with comprehensive programming features and LabView driver, which helps users to easily control the AC source without further needs of programming.

The AFV-P series not only provides AC output to simulate real world grid conditions but can also generate DC output based on user’s settings. It is an ideal cost-effective power testing solution for R&D and certification laboratories.

AFV-P series is a high performance AC power source with fast response time, low total harmonic distortion and tight voltage regulation. With its technically advanced features, users can easily simulate power line disturbance, such as sags, surges, dropouts and spikes.

Response Time: <300µs / THD: <0.3% / Output Frequency: 5-2000Hz

When it comes to over current, AFV-P series offers more than just shutdown protection. Over current foldback enables the AFV-P series to maintain the output current at the rated current and correspondingly decrease the output voltage as the load impedance increases. It is an extended protection or an alternative to provide constant current for EUT.

Ramp and Step feature allows users to define slew rate of voltage and frequency at each Step. Users can set the rise/fall time, time unit and voltage/frequency change between Steps to create a wide range of waveforms. Additionally, Ramp feature can effectively reduce the inrush current by simulating soft start for motor or compressor startup.
