The Helios TSSD 1 is a transformer-based speed controller featuring two integrated transformers mounted on base runners, suitable for connection in a V‑configuration. Designed without an external housing, it is intended for direct installation into a switch cabinet. The unit provides terminal connections for five selectable voltage levels: 0, 80, 140, 280, and 400 volts. Operating at 50/60 Hz, this controller enables precise speed regulation of 3‑phase fans in controlled electrical enclosures.
