The Helios RDS 11 is a high-performance five-step speed controller designed for surface installation, offering precise control over one or multiple fans equipped with thermal contacts. This controller supports voltage levels of 0÷80÷140÷200÷280÷400 volts, enabling flexible speed adjustment to suit a wide range of ventilation systems.
Housed in a durable polymer enclosure rated to IP54, the RDS 11 is suitable for environments exposed to dust or moisture. The unit features an integrated step switch, a control indicator lamp, and a built-in tripping mechanism for added safety. In the event of an overload or fault, the controller can be reset via the “0” position on the selector.
With a maximum ambient temperature of 40 °C, the Helios RDS 11 ensures reliable and efficient operation in commercial and industrial fan control applications.
