Overview

The SolaHD DT631H145S Drive Isolation Transformer is a high-capacity power conversion solution designed for industrial drive systems requiring precise voltage regulation and electrical isolation. Rated at 145 kVA with a 575V Delta primary and 230Y/133V secondary winding, this transformer delivers stable 60Hz output to support high-performance motors and drives. Its robust construction meets UL 506, CSA C22.2 No.66, UL E25872, UL 1561, and cULus E7014 certifications, ensuring compliance with North American safety standards for industrial electrical equipment. Key specifications include a Drive Horse Power rating of 125, making it suitable for heavy-duty applications such as conveyor systems, pumps, fans, and CNC machinery. The transformer’s Delta-Wye configuration provides effective isolation between primary and secondary circuits, reducing voltage spikes, harmonics, and electrical noise that can damage sensitive drive components. This isolation capability extends equipment lifespan and minimizes maintenance costs in variable frequency drive (VFD) applications. The DT631H145S is engineered for compact installation in industrial control panels or dedicated electrical rooms, with dimensions optimized for space-constrained environments. Its high-efficiency core design minimizes energy loss while maintaining consistent voltage regulation across the full load range. The transformer’s secondary output of 230Y/133V supports both line-to-line and line-to-neutral connections, offering flexibility for different motor configurations and control systems. Ideal for new installations or system upgrades, this transformer provides a cost-effective solution to improve power quality in facilities operating at 575V primary voltage. It integrates seamlessly with existing 60Hz industrial power distribution systems, eliminating the need for additional frequency conversion equipment. The unit’s UL listing confirms its suitability for use in both commercial and industrial facilities, including those requiring cULus certification for Canadian markets.
