Coupling Decoupling Networks l CDN
A range of coupling/decoupling networks from Schlöder is available for the surge generator, and for the surge function of the AXOS series from Haefely, which must meet specific requirements. Are the power supply connections AC or DC? Are the cables shielded or unshielded, balanced or unbalanced? These and other questions must be taken into account before selecting the coupling network. We’d be happy to help you with your selection.
