AC fan speed control - analogue input
STVS4 series are transformer fan speed controllers with analogue input. They control three-phase voltage controllable motors with a maximum current of 11 A. The fan speed is regulated by varying the motor voltage in steps. These 5 steps are selected via the analogue control signal (0-10 VDC). The TK monitoring function deactivates the motor in case of overheating. The enclosure allows surface mounting in indoor environments (IP54).
