Construction »»>
The product has a leg type, totally- enclosed structure and its ring core, primary winding and secondary winding are castedresin insulated. Reinsforced insulation makes it workable uner humidity condensation nd pollution ll . Three wiring ways are foryour choise (A.B.C).
The outlet marks of the product are: primary P1 to P2, the secondary current from S1 to S2 through outside returncircuit.High voltage appears if secondary return circuit opens while primary current is flowing by.
