DM220KD - Hammond Power Solutions 3-Phase 220 kVA Drive Isolation Transformer Floor Mount

DM220KD

DM220KD is a three-phase drive isolation transformer designed for industrial applications requiring reliable power distribution and protection for variable frequency drives. This unit features a robust floor-mount design and is built to handle demanding electrical environments. The DM220KD transformer is engineered for high performance with a 220 kVA rating, 60 Hz frequency, and primary voltage options including 208D, 230D, 460D, 480D, and 575D. It is constructed with an aluminum winding and a 220°C (150°C rise) insulation system, providing excellent thermal performance and durability. The transformer is designed to withstand overcurrent of 150% of the rated load for 60 seconds or 200% for 30 seconds, making it suitable for applications with frequent load fluctuations.
