Overview

The Hammond Power DM330CC is a high-capacity three-phase drive isolation transformer designed to meet the rugged demands of AC and DC variable speed drives. Rated at 330 kVA, this transformer operates at 230V primary and secondary voltages with a 600V class rating, making it ideal for industrial motor control and variable frequency drive (VFD) applications. The aluminum wound design ensures lightweight durability and efficient heat dissipation, while the 460V delta primary and 230Y/133V secondary configuration provides the required voltage transformation for VFD systems. With a weight of 1700 lbs (770 kg) and floor-mounting capability, the DM330CC is built for heavy-duty industrial environments. Standard voltages include 230V, 240V, 380V, 460V, 480V, 575V, and 600V, with custom voltages available upon request. The transformer is distributed by Gross Automation and manufactured in the US, ensuring reliable performance and compliance with industry standards.
