INTERNATIONAL SERIES POWER TRANSFORMERS CHASSIS MOUNT TYPE
 
3S Industries international Series power transformers designed and constructed to meet UL, CSA, VDE & IEC U.S. & international standards. This is accomplished by the dual bobbin construction including an overall insulating shroud. The insulation system results in very high isolation between primary and secondary windings and from either to the core. Hipot test is on this transformers 4000VAC RMS.

All 3S industries transformers are 100% tested for turns ratio, exciting current, phasing & hipot.
