Control- and isolating transformer
USTE 100/2x115
Characteristics
General data
The control transformers of the USTE series are designed for universal voltage adjustment and 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
› Touch-protected connection terminals according to UVV BGV A3
› With combination base plate for screw and rail mounting
