Custom Magnetics

Although ECI has a wide selection of standard magnetic products, many applications require either a modification of a standard product platform, or something completely custom and application specific.  At ECI, we design the “total transformer” fully integrating electrical performance parameters, mechanical packaging constraints, end-application environmental conditions and safety agency requirements. ECI “designs for manufacturability” … and we multiple source all critical components.  Please contact our engineering department at (413)562-7684 or
