Solution description

Dual fan speed controller for single-phase motors. The maximum motor current is 7,5 A. Typically, it regulates ventilation systems in a day-night regime or it switches between high and low fan speed based on an external switch or HVAC sensor. Two optimal fan speeds can be selected via the 5-step rotary switches. Via a clock, thermostat or external switch, one of both can be selected.

1 U.

This is a single-phase motor two-speed controller. The maximum motor current (combined) is 7,5 A. This controller has two distinct 5-step switches for selecting between two ideal fan speeds. It is possible to swap between the two specified speeds using the digital input. Normal motor functioning can be indicated by the unregulated output. The fan speed is controlled by lowering the motor voltage using autotransformers. This method produces an output voltage with a perfect sinusoidal form, ensuring silent motor running. The enclosure is surface mountable and provides IP54 protection against dirt, dust, and moisture entry.
