## PAS-F-33150 — Regenerative Grid Simulator (150kVA/300V/45-65Hz, LVRT)

In summary, the Preen PAS-F-33150 is part of the PAS-F Series, a four-quadrant regenerative grid simulator delivering 30 kVA to 1000 kVA with over 90 % energy regeneration efficiency.

The Preen PAS-F Series is a four-quadrant regenerative grid simulator delivering 30 kVA to 1000 kVA with over 90 % energy regeneration efficiency. Engineered specifically for grid-tied device testing — PV inverters, power conditioning systems, V2G chargers — PAS-F integrates LVRT/HVRT functions per IEEE 1547.1-2020 and supports harmonics waveform synthesis for advanced compliance workflows.

### What is the PAS-F-33150 used for?

The PAS-F-33150 is used across photovoltaic inverter test, power conditioning system verification, V2G charger validation, energy storage system integration, and anti-islanding compliance laboratories. Specific test methodologies include IEEE 1547.1-2020 LVRT/HVRT, anti-islanding (Q\_f = 1.0 ± 0.05), DC injection, frequency and voltage trip tests, and harmonics distortion immunity per IEC 61000-4 series.

### Where does the PAS-F-33150 fit in a typical lab workflow?

The PAS-F-33150 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 PAS-F Series is benchmarked against IEEE 1547.1-2020, EN 50530, NB/T 32004, CNS 15382, CNS 15599, IEC 61000-4-34; RoHS Compliant; CE Marked. Within this product line the PAS-F-33150 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.
