The AFV+ series is a high power programmable AC power source utilizing advanced PWM technology to deliver power with THD ≦ 0.5% and up to 2000kVA. The output frequency is 45~120Hz with accuracy of ± 0.02%, and user can select 45~500Hz or 300-840Hz option to expand the frequency. The AFV+ series is ideal to simulate different region's voltage and frequency conditions, and can cover applications for home appliance, motor, medical equipment, lighting and EMC laboratory.
The AFV+ series features STEP and RAMP programmable functions to easily simulate single or continuous output changes. Three phase independent adjustment, optional remote sensing and optional phase angle adjustment all provide convenient control to simulate different kinds of line disturbance. For remote control, the AFV+ series has standard RS-232, RS-485 & Ethernet interface card and optional GPIB and Analog interfaces for easy setup and programming.

Intuitive 7"Touch Screen
The AFV＋ series employs 7"touch screen to provide intuitive and easy-to-use control and display. Users can quickly access output settings and measurements, including voltage, current, frequency, real power, apparent power, PF and sum of each phase's parameters. Complex sequences and system configurations can also be easily done via the touch screen.

Three Phase Independent Adjustment & Phase Angle Control
The Three Phase Independent Adjustment feature of the AFV＋ series can simulate advanced power line disturbance, such as three-phase voltage unbalanced. User can press the icon on the main page of the touch screen to quickly switch from balanced voltage setting to independent voltage adjustment setting. Optional Angle Control is also available to simulate phase shift for different power conditions.

RAMP and STEP Programming Features
The AFV＋ series' RAMP feature has up to 12 sequences available with parameters of voltage, frequency and time, and the STEP feature has up to 24 sequences available with parameters of voltage, frequency and time. These features provide an easy method to simulate different kinds of power line disturbance.

Remote Control Software: Preen Program
The AFV＋ series offers complimentary remote control software, Preen Program. This graphical user interface provides easy settings and user-friendly configurations for users to fully control the unit. The Preen Program includes GENERAL mode or PROGRAMMABLE mode with STEP and RAMP features available. The preview waveform and report functions also greatly enhance convenience for review parameters and results before or after testing.
