The Preen AFVPLUS31120 High Power Programmable AC Power Source, 120KVA, 300V, 45-65Hz, 3 Phase In, 1 Phase Out is a high power programmable AC power source utilizing advanced PWM technology to deliver power with THD ≤ 0.5% and up to 120kVA. The output frequency is 45~65Hz with accuracy of ± 0.02%. 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 AFVPLUS31120 features STEP and RAMP programmable functions to easily simulate single or continuous output changes. Three phase independent adjustment provides convenient control to simulate different kinds of line disturbance. These features are ideal for test applications of R&D design verification, quality assurance and production checks. 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. For remote control, the AFV＋ series has standard RS-232/RS-485/RS-422 interface card for easy setup and programming.

The AFV-Plus-31120 employs a 7 in. 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.

This model includes 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 on review parameters and results before or after testing.
