Construction:

These transformers are provided with Recognized Component electrical

insulation system (OBJY2), Class 130 (B), designated “B3”. Products are

designed, built and 100% tested for a hi-pot of 2500V, winding to winding and

1250V, winding to core.

Agency Files:

UL file E50476

– Electrical Insulation Systems, Class “B3”, 130C

RoHS Compliance: As of manufacturing date February 2005, all standard

products meet the requirements of 2011/65/EU, known as the RoHS initiative.
