DM027JH - Hammond Power Solutions 27 kVA 460D-400Y Drive Isolation Transformer

DM027JH

DM027JH is a 27 kVA three-phase drive isolation transformer manufactured by Hammond Power Solutions, designed for industrial applications requiring voltage conversion and motor drive isolation. This unit features a 460 Delta primary voltage and 400 Wye secondary voltage configuration at 60 Hz, making it ideal for variable frequency drive (VFD) applications and load isolation in demanding environments.Technical Specifications: The transformer utilizes an aluminum construction with a 220 degrees Celsius insulation class and 150 degrees Celsius temperature rise rating. It operates at 60 Hz frequency and is rated for 27 kVA capacity. The secondary connection is configured as Wye with neutral (400Y/231V). Sound level is rated at 45 dBA per NEMA ST-20 standards. The unit features an NH6 case style and supports both floor and wall mounting configurations. Impedance is typically 3 to 6 percent. The transformer meets UL and CSA short circuit withstand requirements.
