PFV-33100 — Regenerative AC Power Source (100kVA/300V/45-65Hz)

In summary, the Preen PFV-33100 is part of the PFV Series, a four-quadrant regenerative AC power source delivering 30 kVA to 400 kVA in three-phase.

The Preen PFV Series is a four-quadrant regenerative AC power source delivering 30 kVA to 400 kVA in three-phase. PFV provides the same regenerative architecture as the PAS series — energy returned to the grid at over 90 % efficiency — without the LVRT/HVRT compliance package, making it ideal for grid-tied device testing where power-recycling is the priority.

What is the PFV-33100 used for?

The PFV-33100 is used across inverter manufacturing test, motor controller validation, regenerative cycling, and any high-power AC test workflow where energy recycling reduces operating cost. Specific test methodologies include grid-tied device input/output simulation, motor regenerative test, and battery management system AC interface validation.

Where does the PFV-33100 fit in a typical lab workflow?

The PFV-33100 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 PFV Series is benchmarked against RoHS Compliant; CE Marked. Within this product line the PFV-33100 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.
