FAQs
Plan for indoor installation in a stable, vibration-minimized space. The unit weighs 780 lb and uses a CASE D frame with a NEMA 1 enclosure, so ensure secure floor mounting, adequate clearance for cooling, and proper lifting equipment during placement. Consider 2 AT +2.5% FCAN and 4 AT -2.5% FCBN taps for voltage regulation to match site conditions.
DOE 2016 efficiency reduces core and copper losses, improving overall energy performance. This transformer is UL Listed and meets 10 CFR Part 431 requirements, offering predictable operating cost savings. With 150 kVA rating and 60 Hz operation, it delivers stable voltage conversion with low stray losses, contributing to cooler operation and reduced cooling energy needs.
Yes. With a 150 kVA three-phase rating, 480 V delta primary, and 208Y/120 V secondary, it supports critical loads in data centers and factory floors. The K-Factor nonlinear ventilated design helps manage harmonics from drives and controllers, while the 47 dB sound rating keeps noise within acceptable levels in work environments.
Key certifications include UL Listed status and DOE 2016 efficiency compliance, along with 10 CFR Part 431 (2016) efficiency notes. The enclosure supports indoor installations (NEMA 1), and the unit uses copper windings with a 220 °C insulation rating, providing robust thermal and safety margins for regulated facilities.
The combination of DOE 2016 efficiency, UL Listed certification, and robust construction lowers energy costs and reduces maintenance frequency. The copper windings and high insulation rating extend service life, while the voltage-tap options minimize downtime from voltage drift. Although installation is weight-intensive, the unit’s reliability and efficient operation translate into meaningful long-term savings on ownership.
