VAC2-3/RFI, 3A, 230V

Description

The VAC2-3/RFI is a compact, high-performance single-phase fan controller, designed to regulate up to 3A of inductive loads such as induction motors, fans, and pumps. Operating at 230V, this open-construction variable phase angle regulator provides fully adjustable voltage outputs from zero to maximum, ensuring precise control for various applications.

Engineered with an integral RC Snubber network, the VAC2-3/RFI excels at managing inductive loads, preventing issues like voltage spikes. The controller also features a multi-turn cermet Minimum Set Speed adjuster, allowing designers and installers to set a minimum output voltage, thereby preventing motors from running too slowly.

To meet current EMC standards for emissions, the controller includes an integral choke/capacitor RFI circuit. Its large Triac is built to handle high inrush currents, offering a robust safety margin for industrial installations. For added convenience, an adhesive-backed silver label and hairline knob are available as optional extras for front panel mounting.
