AFV-S-1250 — Programmable AC Power Source (1250VA/310V/40-500Hz)

In summary, the Preen AFV-S-1250 is part of the AFV-S Series, a compact, single-phase programmable AC power source delivering 600 VA, 1250 VA, 2500 VA, or 5000 VA in 2U/4U rack chassis.

The Preen AFV-S Series is a compact, single-phase programmable AC power source delivering 600 VA, 1250 VA, 2500 VA, or 5000 VA in 2U/4U rack chassis. It provides 0–310 V output, 40–500 Hz, low harmonic distortion, and a 5″ touch screen for precise control in production-line and laboratory automation.

What is the AFV-S-1250 used for?

The AFV-S-1250 is used across home appliance testing, power connectors and LED lighting verification, manufacturing automation, and laboratory R&D requiring compact, precise single-phase AC simulation. Specific test methodologies include production-line voltage/frequency sweep testing, power-quality measurement, and remote-controlled ATE integration.

Where does the AFV-S-1250 fit in a typical lab workflow?

The AFV-S-1250 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-S Series is benchmarked against RoHS Compliant; CE Marked. Within this product line the AFV-S-1250 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.
