Isolating transformer
ETTK 630
Characteristics
General data
The isolating transformers of the ETTK series are designed for mobile applications and ensure safe galvanic isolation of the primary circuit from the secondary circuit. The transformers are manufactured according to EN (IEC) 61558-2-6 and can be used for the protective measure of protective separation in accordance with VDE 0100.
Benefits
› Integrated short-circuit and overload protection
› Excellent moisture protection and low noise emission thanks to XtraDenseFill resin encapsulation
› Very high protection class
› Carrying handle, safety socket for mobile use
