The Helios TSSD 7 is a dual-transformer speed controller designed for managing 3‑phase fans in a V‑connection setup. It features two integrated transformers mounted on base runners and is intended for installation inside a switch cabinet, with no external housing. The unit offers terminal connections for five selectable voltage levels: 0, 80, 140, 280, and 400 volts. Operating at 50/60 Hz, the TSSD 7 provides precise and efficient fan speed regulation in controlled electrical installations.
