The Helios TSSD 11 is a transformer-based speed control unit featuring two integrated transformers mounted on base runners for use in V‑connection setups. Designed for direct installation into a switch cabinet, this unit comes without a housing. It provides terminal connections for five voltage levels: 0, 80, 140, 280, and 400 volts. Operating at 50/60 Hz, the TSSD 11 offers precise control of 3‑phase fan speeds in enclosed electrical control environments.
