Overview

The SolaHD DT651H27S Drive Isolation Transformer is a 27 kVA unit designed for motor drive applications, providing reliable electrical isolation between primary and secondary circuits. With a 460V Delta primary and 460Y/266V secondary configuration, this transformer operates at 60 Hz to match standard North American power requirements. Rated for 20 HP drive applications, it delivers clean, stable power to protect sensitive electronics and motors from voltage transients, harmonics, and electrical noise. Key specifications include a 27 kVA power rating, 460V Delta primary input, and 460Y/266V secondary output. The transformer’s Delta-to-Wye (460Y/266) connection ensures balanced voltage distribution while suppressing common-mode noise—a critical feature for variable frequency drives (VFDs) and other motor control systems. Its compact design allows for easy integration into control panels, motor drive enclosures, or dedicated transformer cabinets. Applications span industrial automation, HVAC systems, pump controls, and manufacturing equipment where precise voltage regulation and electrical isolation are required. The DT651H27S is optimized for environments with high harmonic distortion, providing extended equipment life by reducing stress on motors and drives. Compatible with SolaHD’s DT651H series, this transformer maintains consistent performance under continuous duty cycles. For systems requiring compliance with North American electrical standards, the DT651H27S meets industry-recognized safety and performance criteria. Its robust construction ensures reliable operation in demanding industrial settings, from small-scale machinery to large-scale production lines.
