Safety:
These units are designed with 1500V isolation between the winding and the
core. Materials and construction are rated for Class B insulation system.
BLK
Description:
Secondary coil is a fraction of the entire winding for voltage step-down.
This causes part of the power to be transferred conductively through the
windings, rather than all of the power being transferred by induction.
