Control- and safety isolating transformer

STEU 160/24

Characteristics

General data

The transformers of the STEU series ensure safe galvanic isolation of the primary circuit from the secondary circuit. The unique BLOCK IMPEX vacuum impregnation process provides excellent protection against external influences while reducing noise levels. Installation is simple and quick thanks to the innovative push-in terminal technology.

Benefits
