Three phase Epoxy Encapsulated Transformer BC9C-N1/EP is an isolation transformer with primary and secondary windings that are physically separated from each other. It allows AC power to be taken from one device and fed into another without electrically connecting the two circuits. The transformer blocks transmission of DC currents but allow AC signals to pass. It is sealed in silica sand and resin solid mass, completely enclosing and protecting the core and coil, while significantly reducing audible noise and suitable for hazardous environments.
