Speed regulators include a range of solutions designed to adapt fan performance to system requirements. Each type ensures that motor operation is matched to the fan’s operating curve, providing different benefits in terms of ease of use, elimination of electrical noise, energy savings, and system customization. This makes it possible to select the most suitable solution according to the motor type (single-phase or three-phase) and the required control parameters.
Single phase electronic speed regulators
Manual voltage regulator with continuos regulation by potentiometer. Electronic tuning by triac phase control, closed loop type. Suitable for single phase asynchronous adjustable motors.
Single-phase (SRS-M) and three-phase (SRS-T) autotransformer speed controllers
Manual autotransformer voltage controllers with a 5-step preset speed selector. They eliminate electrical motor hum and are suitable for speed-controllable single-phase (SRS-M) and three-phase (SRS-T) asynchronous motors.
Electric panels for diffusers
The common characteristic of the electric panels QEA is the step graduated transformer speed regulation that guarantees an optimal regulation. The control modules are MPU and digital for ease of use. The wideness of the regulation parameters allows the customising of the plant to be controlled.
The electric panels QEA are supplied with feeler for detecting the temperature, suitable for connection to standard bipolar cable for long distance.
Inverter
The FRC inverter is a speed controller for asynchronous motors that precisely controls motor rotation, adapting it to the fan’s operating curve. It ensures significant energy savings and optimal regulation without magnetic noise.
