DM007NNCN - Hammond Power Solutions Drive Isolation Transformer 7.5 kVA 575V 3-Phase

DM007NNCN

DM007NNCN is a three-phase drive isolation transformer rated at 7.5 kVA with 575 Delta primary voltage and 575Y secondary voltage, designed for industrial drive applications requiring voltage isolation and harmonic filtering.

This standard non-efficient transformer features copper wound construction with precision-balanced conductors to minimize axial forces during short-circuit conditions. The unit meets UL and CSA short circuit withstand requirements and operates at 60 Hz frequency. With a 220 degrees Celsius insulation system and typical 150 degrees Celsius temperature rise, the transformer delivers reliable performance in demanding environments. The core is coated to prevent moisture ingress, and the robust interface between core and coils ensures superior short circuit performance. Impedance typically ranges from 3 to 6 percent.
