400 V motor 2,5 A | temperature control

This transfomer fan speed controller is intended for three-phase 400 V motors and has a built-in calendar function which can be used for configuring the fan parameters a year ahead. The (combined) maximum current is 2,5 A. Two optimal motor speeds can be selected. It can be configured to switch between two optimal speeds using the day-week programming functionality. AC fan speed is regulated by reducing motor voltage via autotransformer technology. This technology generates a motor voltage with perfect sinusoidal shape, guaranteeing quiet motor operation. TK monitoring function deactivates the motor in case of overheating. After a power failure, the motor will automatically restart. The enclosure is surface mountable indoors (IP54). The supply voltage is 400 VAC.

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.
