Programmable Simulations: Transient Feature

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 precompliance tests and various types of power line disturbance, such as surge, sag, spike and dropout, for immunity tests.

Ideal for High Inrush Current EUT & Start / End Angle Setting

For switching supply (rectified load), AFV-P-600 and AFV-P-1250 provide standard inrush current as 4.5 times of max. output current, and optional 9 times of max. output current is also available as option, which make AFV-P series the lowest capacity in the market that can achieve the highest inrush current. The user doesn’t have to buy high capacity power supply just in keeping with the high inrush current characteristic of the load. Reduce the costs and save the space.

Capable of sustaining high start inrush current generated by motor or compressor.

The AFV-P series can provide up to 4.5 times of peak current from its maximum rated current, which is ideal for inrush current test, such as electric motor test. Additionally, the AFV-P series allows user to set the start angle/end angle for the product output, which is suitable for testing switching power supplies.

Intuitive Touch Screen Control

To create a complex sequence on the HMI is no longer a difficult task for AFV-P series. The 5 inches touch screen provides users a clear display and an easy set up. AFV-P is also equipped with a rotary knob for better fine tune adjustments.

Multiple Communication Interfaces & Control Software

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. AFV-P also provides control software with comprehensive programming features and LabView driver, which help users to easily control the AC source without further needs of programming.

Programmable Simulation: Step & Ramp Features

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 waveform. Additionally, Ramp feature can effectively reduce the inrush current by simulating soft start for motor or compressor startup.

AC & DC Output

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

AC & DC Output

AFV-P series has the industry leading power density and rackmount type design for easy system integration. 2500VA only comes in 2U and 5000VA is only in 4U.

Fast Response & High Stability

AFV-P series is a high performance AC 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.

Screen Lock Password

In order to prevent the operator from changing the set parameters by mistake, the new Screen Lock Password function is added on AFV-P series, so that the operator can only perform the output of the device, and only authorized personnel has the password to unlock the screen and edit parameters.

High Voltage Output 620V/1240V (Option)

AFV-P series provides optional high-voltage output 620V or 1240V to meet the high voltage requirements on simulations of wide input voltage variations (15%~20%), over-voltage and other extreme conditions. For example, it can simulate US 277V with at least 15%

LED TRIAC Dimmer (Option)

AFV-P series provides optional LED TRIAC Dimmer function, which can simulate output of TRIAC dimmer. The user can select whether to perform LEADING EDGE DIMMING or TRAILING EDGE DIMMING via HMI. Compared with traditional TRIAC dimming, the output waveform can be controlled more accurately and effectively.

Shortcuts of Output Memory Set (Basic Mode)

1. One user-assigned shortcut from 50 memory sets
2. Three fixed shortcuts from first three memory sets

AFV-P series can display 4 shortcuts of Memory Sets in BASIC Mode, 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. Also, the Screen Lock function is also provided for preventing operators from acciden
