NEW - Low to high fan speed controllers
SDY are AC fan speed controllers. They regulate fan speed from low to high. Designed for single-phase voltage controllable motors with a maximum current of 3 A. Their enclosure allows inset mounting or surface mounting. The new SDY 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.
