AC motor 5 A | 3-step fan speed control

This 5-step fan speed controller may be controlled remotely via 5 inputs. It controls single-phase motors. The maximum current (combined) is 5 A. The AC fan speed is controlled by adjusting the motor voltage in up to five levels. An external switch or control device can be used to choose the various processes. The control switch type SMT-1-30-4C is recommended. This is a three-position switch with an off position. The exact sinusoidal form of the output voltage ensures silent motor running. Surface mounting is possible in indoor environments (IP54). The power supply voltage is 230 volts.

The SMT-1-30-4C is a control switch designed to facilitate the way you manage single-phase multi-stage or multi-speed motors. It is a passive switch that operates seamlessly without the need for external power. This device distributes a mains line signal to various outputs, providing precise control over your motor performance based on the switch position. Crafted with precision, the SMT-1-30-4C features an OFF position and three distinct outputs, facilitating a transfer of the supplied 230 VAC to one of the three terminal blocks. This functionality empowers you to fine-tune the speed of your multi-speed fan with ease, offering three distinct steps for optimal customisation. With contact ratings of 10 A for resistive loads and 3 A for inductive loads, the SMT-1-30-4C ensures reliability and efficiency in every application. The enclosure allows for both inset mounting (IP44) and surface mounting (IP54). This flexibility ensures compatibility with various environments, providing you with the freedom to choose the installation method that best suits your needs.
