DM011NNCN - Hammond Power Solutions Drive Isolation Transformer 11kVA 575V 3PH

DM011NNCN

DM011NNCN is a three-phase drive isolation transformer rated at 11kVA with 575-volt primary and secondary voltages, designed for industrial drive applications requiring voltage isolation and harmonic filtering. This transformer features an encapsulated core and coil construction with electrical-grade silica sand and resin compounds that seal out moisture and contaminants, ensuring reliable long-term performance in demanding environments. The unit is precision-wound with aluminum conductors that are electrically balanced to minimize axial forces during short-circuit conditions, and includes a robust interface between core and coils for enhanced short-circuit performance.
