Single phase Isolating Transformers

 
 

 

 

Single phase EI-Transformers

These dry type transformers are based on EI standard series in conformity with the DIN standard 41302. The design, construction and testing meet the safety requirements in conformity with standard IEC61558.

   The transformers are constructed with high quality silicon steel to increase efficiency.

   Designs incorporate precision wound coils for improved regulation.

   CLASS B (130OC) or CLASS H (180OC) Insulation materials.

    The core and the coils are completely vacuum-impregnated with polyester UL approved varnish.

 

Standard Isolating transformers

The standard EI transformers manufactured by us are IS61558 (IEC61558) approved by the Standards Institution of Israel.

These transformers are designed to operate 12V halogen lamps, and general-purpose 12V or 24V electrical equipment.
