FAQs
The transformer is a three-phase unit with a 480 V primary and 480Y/277 V secondary, designed for 60 Hz operation. It features taps at +2.5% and -2.5%, a sturdy 918A frame, and copper windings suitable for retrofit or new builds. For outdoor installations, WS34 weather shielding and electrostatic shielding mitigate EMI. Plan for substantial floor loading (1955 lb) and ensure adequate clearance, enclosure, and mechanical support in the electrical room.
Key specs include a 150 kVA rating, three-phase configuration, 60 Hz frequency, 80 °C rise, and copper windings. The +/− taps optimize voltage under load or feeder losses, while KT-13 K-Factor rating supports nonlinear loads. Benefits for data centers include stable voltage to IT racks, reduced harmonic stress, improved reliability, and energy-efficient operation through NEMA TP-1 compliance and efficient design.
Yes. The transformer is labeled as K-Factor nonlinear and KT-13 rated, meaning it is specifically designed to tolerate and mitigate harmonics from non-linear loads. Electrostatic shielding further reduces EMI, contributing to cleaner power quality for sensitive equipment like server racks and drives. This makes it well-suited for modern facilities with mixed non-linear loads.
This unit is UL Listed and NEMA TP-1 compliant and efficient. UL Listing assures product safety and reliability for industrial installations, while NEMA TP-1 compliance confirms efficiency and performance under standardized testing. For manufacturers and integrators, these certifications simplify procurement, permit processes, and energy compliance reporting across facilities.
With copper windings, robust cooling (80 °C rise), and a durable 918A frame, the transformer is built for long service life with minimal maintenance. Warranty guidance includes a one-year policy from installation or 18 months from shipment. While a high initial weight requires proper mounting, the high reliability, reduced downtime, and energy efficiency contribute to favorable total cost of ownership and faster ROI in critical facilities.
