VAC1/RFI & VAC2/RFI X10380 Up to 3A, 110V, 230V Single Phase Fan Controller 0044 (0) 1704-516 501 enquiries@united-automation.com www.united-automation.com CONTACT US: INSTALLATION DIMENSIONS & CONNECTIONS  VAC1-1 RFI & VAC2-1 RFI WARNING! DISCONNECT FROM SUPPLY BEFORE CARRYING OUT ANY SERVICING WORK KEY FEATURES: The VAC2-1/RFI, VAC2-3/RFI, and VAC1-1/RFI single-phase fan controllers are compact, variable phase angle regulators designed for precise control of motors, fans, and pumps in industrial and commercial environments. Operating at 230V for the VAC2 models and 110V for the VAC1, these controllers offer 0-98% adjustable voltage output, ensuring smooth, reliable operation. With robust Triac inrush protection, RC Snubber technology, and EMC compliance, they handle high inrush currents while meeting modern standards for electrical noise suppression.  Infinitely adjustable output from 0-98%.  Minimum Set Speed Adjuster to prevent slow motor operation.  Triac inrush protection for safe high-current handling.  Integral RC Snubber for smooth inductive load control.  Built-in EMC filtering for compliance with emission standards.  Rugged, compact design with single hole fixing for easy installation.
