TDID 18A – EA900035 – Transformer Three Phase – Flakt Woods

TDID 18A – EA900035 – Transformer Three Phase – Flakt Woods The TDID transformer speed controllers are based on the principle of voltage control with auto-transformers. They are applicable to three phase voltage-controllable motors (400 VAC, 50/60 Hz), to control the rotational speed of fans in five steps. They are fitted out with contacts for motors equipped with thermostat(Tk) overheat protection. A safety isolator/switch disconnector should be installed on the mains side of all motor drives; refer to SISO.
