Analogue input motor control
STVS1 series are transformer fan speed controllers with analogue input. They control single-phase voltage controllable motors with a maximum current of 13 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 protect the motor against overheating. The enclosure allows surface mounting in indoor environments (IP54).
