Product Description
United Automation VAC2-3/RFI Series Fan Speed Controller is a highly reliable device designed for adjusting the speed of induction motors, fans, and pumps in industrial and HVAC settings. Operating at 230V AC ±10% with a frequency of 50/60 Hz, it supports inductive loads with precise control through its infinitely variable phase-angle regulation.
This fan speed controller delivers a maximum RMS on-state current of 3A and a minimum operating current of 100mA, making it suitable for varied load requirements. The product includes integrated RFI filtering circuitry which ensures compliance with current electromagnetic compatibility standards, reducing interference in sensitive environments.
Equipped with a large triac, integral RC snubber, and choke/capacitor components, the VAC2-3/RFI safeguards against inrush currents and voltage spikes, enhancing both performance and lifespan. Its robust construction supports operation up to +70ºC ambient temperature.
This controller is ideal for use in industrial automation, HVAC systems, manufacturing plants, and water treatment facilities where precise fan and pump speed regulation is critical for energy efficiency and process control.
The VAC2-3/RFI offers infinitely variable 0-98% output for smooth speed adjustments. Rated for a maximum current of 3A RMS ensuring compatibility with medium power equipment. Integral EMI/RFI filtering for compliance with EMC regulations and reduced noise emissions.
Designed for 230V single-phase supply with 50/60 Hz frequency flexibility. Compact design with single hole fixing for convenient mounting. Large triac and integral RC snubber provide inrush current protection and enhanced reliability.
Peak surge current rating of 150A ensures robust transient tolerance. Recommended maximum unit temperature of +70ºC for stable operation in demanding environments. Applications include industrial automation, HVAC fan speed control, and motor regulation in pumps.
