AC motor 10 A | temperature based fan speed control

Two-speed controller for single-phase motors. the (combined) maximum current is 10 A. The controller has two independent 5-speed switches for selecting two optimal fan speeds. Switching between both selected speeds is possible via a digital input. An unregulated output can be used to indicate normal motor operation. The fan speed is controlled by reducing the motor voltage through an autotransformer. This technology results in a perfectly sinusoidal output voltage and guarantees quiet motor operation. The housing can be surface mounted and is IP54 rated against dirt, dust and moisture.

This mechanical thermostat controls temperatures between 0 and 40 °C. The output contact can switch loads up to 16 A. The requested temperature can be adjusted via the rotary knob. The ambient temperature is measured via the spiral sensor. This thermostat can be used for heating or cooling ventilation applications in warehouses, greenhouses, stables, etc. The enclosure can be wall-mounted. It offers an IP54 protection against ingress of dust and moisture. This thermostat does not require a supply voltage.
