The Helios MWS 10 is a five-step fan speed controller designed for surface-mounted installations. It enables connection of thermal contacts from one or multiple fans via a terminal block. Housed in a durable polymer casing with IP54 protection, it operates effectively in environments up to 40 °C.
This controller features a step switch allowing voltage selection at 0, 80, 100, 130, 170, and 230 volts. It includes an integrated tripping device and an indicator lamp for fault monitoring. After a trip or failure, the system restarts via the “0” switch position. The MWS 10 offers precise and secure control for multi-fan systems in commercial and industrial ventilation applications.
