Overview

The Versa Air Circulator Fan Controller is a high-efficiency BLDC drive designed for commercial and industrial air circulator fans. It operates from a single-phase 180–300 Vac input and drives a 230 Vac, 3-phase BLDC motor rated up to 180 W, using field-oriented control (FOC) for smooth torque and low acoustic noise.

This controller is intended for high-performance air movement – pedestal or wall-mounted air circulators, industrial air movers, and similar equipment – where precise speed control and energy efficiency are more important than simple on/off operation. With >93.5% drive efficiency and integrated protections, it helps OEMs reduce heat load and improve energy performance in dense installations such as production floors or data-center support areas.
