Characteristics

General data

The control transformers of the STE 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

› Control and isolating transformer according to EN (IEC) 61558-2-2 and EN (IEC) 61558-2-4

› Very good inrush behavior due to reduced inrush currents

› High power density through a compact design concept

› Primary side ±5% taps for voltage adjustment

› Touch-protected connection terminals according to UVV BGV A3
