The Preen AFV-P Series is a high-performance single-phase programmable AC power source delivering 600 VA to 6 kVA with selectable AC and DC output, low THD (≤0.3% at 5–100 Hz), and ≤300 µs response time. The series provides clean, programmable mains simulation for IEC 61000-4-11/14/28 pre-compliance, motor and switching-supply testing, and design-verification workflows. ### What is the AFV-P-1250B used for? The AFV-P-1250B is used across home appliance, R&D and certification laboratories, switching power supplies, motors and compressors, EV charger input simulation, aerospace and defense pre-compliance, and IT/SMT production lines. Specific test methodologies include IEC-61000-4-11 voltage dip / dropout, IEC-61000-4-14 voltage fluctuation, and IEC-61000-4-28 frequency variation pre-compliance testing. ### Where does the AFV-P-1250B fit in a typical lab workflow? The AFV-P-1250B 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-P Series is benchmarked against IEC 61000-4-11, IEC 61000-4-14, IEC 61000-4-28; RoHS Compliant; CE marked; Taiwan Excellence Award recipient. Within this product line the AFV-P-1250B 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. ## Accessories Supplied - Input power cable (length by chassis: 1.8 m for 600 VA, 3 m for 1.25/2.5 kVA, 5 m for 5 kVA) - Quick-start / operation manual - PC control software and LabVIEW driver (download) - Calibration certificate (when applicable) ## Specifications Specifications below are for the AFV-P Series.
