The CS4200V-01L is a 35A Current-sensing Transformer designed to meet UL/CSA/IEC 60950 reinforced insulation specification and provide 3mm creepage/clearance between primary and secondary windings. Winding to winding isolation is 3750Vrms. Varying the terminating resistance allows sensitivities of 1 to 100V output per ampere input. In this Coilcraft current sensing transformer, the current and sense windings are incorporated in one small, encapsulated package requiring minimum board space.
