Advanced fan speed control - TK monitoring - high-low speed
SC2A1 series are transformer fan speed controllers with day-night function and TK monitoring. Two optimal motor speeds can be selected. The integrated change-over input, makes it possible to select one of these optimal motor speeds. A clock, thermostat or switch can be connected to the change-over input. The TK monitoring function protects the motor in case of overheating. Single-phase voltage controllable motors with a maximum current of 13 A can be controlled. The output voltage with perfect sinusoidal shape, guarantees quiet motor operation.
