400 V motor 1,5 A | temperature control | TK monitoring

This is a two-speed controller with thermal contacts (TK) for 400 V motors. The maximum motor current (combined) is 1.5 A. This controller has two distinct 5-step switches for selecting between two ideal fan speeds. When the motor is turned on, a dry contact input may be used to switch between the two speeds. In the event of overheating, the TK monitoring feature shuts the motor. The motor will automatically resume after a power outage. The alarm and unregulated outputs can be used to operate external devices in order to produce alerts or validate normal operation. 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.

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.
