AFC-31045 — AC Power Source / Frequency Converter (45kVA/310V/45-65Hz Single-Phase 3PH In)

In summary, the Preen AFC-31045 is part of the AFC Series, a clean-sine-wave AC power source and frequency converter delivering 5 kVA to 2000 kVA in single- or three-phase.

The Preen AFC Series is a clean-sine-wave AC power source and frequency converter delivering 5 kVA to 2000 kVA in single- or three-phase. With selectable 45–65 Hz continuous operation plus optional fixed 100/120/200/240/400 Hz outputs, AFC simulates international mains conditions and serves as a precise voltage / frequency converter for global product testing.

What is the AFC-31045 used for?

The AFC-31045 is used across home appliance testing, motor and compressor production, EMC chamber simulation, smart grid testing, factory production lines, laboratory verification, EV charger input simulation, and medical equipment validation. Specific test methodologies include voltage and frequency conversion between regional mains standards, three-phase unbalanced load handling, and electronic-motor-type product activation requiring high inrush capacity.

Where does the AFC-31045 fit in a typical lab workflow?

The AFC-31045 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 AFC Series is benchmarked against RoHS Compliant; CE Marked. Within this product line the AFC-31045 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.
