AFV-PLUS-31030 — High Power Programmable AC Power Source (30kVA/310V Single-Phase)

In summary, the Preen AFV-PLUS-31030 is part of the AFV+ Series, a high-power programmable AC power source covering 10 kVA to 2000 kVA in single- or three-phase output.

The Preen AFV+ Series is a high-power programmable AC power source covering 10 kVA to 2000 kVA in single- or three-phase output. Using advanced PWM control, AFV+ delivers ≤0.5 % THD, 0.5 % F.S. voltage accuracy, and selectable 45–500 Hz operation with optional 300–840 Hz for avionics and motor double-frequency testing.

What is the AFV-PLUS-31030 used for?

The AFV-PLUS-31030 is used across home appliance, EMC laboratory, EV charger and high-voltage motor testing, medical equipment, aerospace and defense, transportation, shore power, and three-phase production lines. Specific test methodologies include phase shifting and 3-phase imbalance testing, EV charger high-power AC input simulation, motor double-frequency testing, transformer testing, and grid voltage / frequency simulation across global mains standards.

Where does the AFV-PLUS-31030 fit in a typical lab workflow?

The AFV-PLUS-31030 integrates into bench, ATE, and high-power production environments through standard RS-232, RS-485, Ethernet, and USB control. Engineers use it to repeatably simulate global mains and DUT operating conditions during design verification, certification pre-compliance, and end-of-line testing — replacing manual variac/MG-set configurations and improving test repeatability and data capture.

From a measurement standpoint, the AFV+ Series is benchmarked against RoHS Compliant; CE Marked; supports IEC 61000-4-11 / IEC 61000-4-34 input conditions. Within this product line the AFV-PLUS-31030 delivers the variant-specific output described in this model's specification block below — chosen to match the most common DUT power, voltage, and frequency requirements in the target application.

Preen (AC Power Corporation, founded 1989) is one of the world's highest-volume programmable power-source manufacturers, with ISO 9001:2015 certified manufacturing facilities in Taipei, Tianjin, and Suzhou, and a U.S. service center in Irvine, California. Preen products carry CE and RoHS certifications and have been recognized with multiple Taiwan Excellence Awards for the AFV, AFV-P, and ADG-P product lines — placing the brand in the established commercial tier alongside California Instruments, Chroma, and Pacific Power Source.

How does it compare to alternative AC/DC sources?

• Compared with California Instruments and Pacific Power Source: Preen typically offers 10–20% lower pricing with strong multi-phase capability — ideal for budget-conscious compliance labs and three-phase applications.
• Compared with Chroma 61800 series: Preen provides comparable programmability and broader high-power three-phase coverage at competitive ASP.
• For avionics 400 Hz testing, Preen frequency-converter options (AFC) and AFV+ Type-C 300–840 Hz cover MIL-STD-704 / DO-160 workflows.
