ATT Series - Overview
Application
Three phase auto-transformers for switch cabinet installation with compact design. Auto-transformers (open model according to EN61558) are provided with finger proof (IP20) connecting clamps, fastening clips and 5 branches. Transformers based voltage controller. For switch board mounting, they can be used, in V-connection, with voltage controllable motors (400 Vac, 50/60 Hz) for adjusting the rotational speed (fans, pumps, etc.).When choosing a transformer, it is important to know the maximum current intensity consumption. The given intensity can be taken from every tapping.
