The Helios RDS 4 is a five-stage speed controller designed for surface installation, suitable for managing one or more fans equipped with thermal contacts. It connects directly via a terminal block, providing reliable control within the rated load.
Offering selectable voltage settings of 0÷80÷140÷200÷280÷400 volts, this controller enables flexible fan speed adjustment. It includes a step selector switch, an integrated trip mechanism, and a status indicator lamp. In the event of a fault, operation is resumed by returning the switch to the “0” position.
Encased in a durable polymer housing with IP54 protection, the RDS 4 is ideal for demanding environments with ambient temperatures up to 40 °C, ensuring safe and efficient fan operation in commercial and industrial settings.
