AFV-33030 — High Power Programmable AC Power Source (30kVA/310V/45-120Hz Three-Phase)

In summary, the Preen AFV-33030 is part of the AFV Series, a programmable high-power AC power source covering 10 kVA to 1600 kVA in single- or three-phase.

The Preen AFV Series is a programmable high-power AC power source covering 10 kVA to 1600 kVA in single- or three-phase. Built for compliance, R&D, and certification environments, it provides 0–310 V output with 45–120 Hz standard (45–500 Hz optional), STEP/RAMP programming, and complete remote-control interfaces.

What is the AFV-33030 used for?

The AFV-33030 is used across home appliance manufacturing, electronics certification, motor and compressor testing, EMC laboratories, EV charger input simulation, medical devices, and industrial automation. Specific test methodologies include simulating international mains voltage and frequency, motor soft-start testing, power line disturbance simulation, three-phase imbalance simulation, and unbalanced 100% load testing.

Where does the AFV-33030 fit in a typical lab workflow?

The AFV-33030 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; Taiwan Excellence Award. Within this product line the AFV-33030 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.
