NEW - High to low fan speed controllers
SDX are AC fan speed controllers. They regulate fan speed from high to low. Designed for single-phase voltage controllable motors with a maximum current of 3 A. The enclosure allows inset mounting or surface mounting. The new SDX series are microprocessor controlled to guarantee accurate motor control and to minimise motor noise. Phase angle control - Triac technology - is used to vary the motor voltage and to regulate the motor speed.
