FAQs
This transformer uses a CASE D enclosure with a NEMA 1 frame suitable for indoor or protected environments. It weighs about 1200 lb and measures 26.5 in long, 40.5 in wide, and 51.5 in high. Plan sufficient clearance for access to taps (2 AT +2.5% FCAN and 4 AT -2.5% FCBN), cooling, and service clearance per local code. Ensure compatibility with 480 V delta primary and 208Y/120 V secondary circuitry and proper mounting hardware for heavy equipment.
Key specs include a 150 kVA rating at 60 Hz, primary 480 V delta, secondary 208Y/120 V, aluminum windings, and a 150°C insulation rise. The unit supports 3-phase operation, a 150 kVA/VA rating, and tap settings for voltage adjustment (2 AT +2.5% FCAN, 4 AT -2.5% FCBN). These ensure stable voltage conversion, voltage regulation under load, and compliance with DOE 2016 efficiency targets.
Yes. Its 150 kVA rating and 60 Hz operation suit large loads common in data centers and production environments. The 480 V delta to 208Y/120 V secondary configuration supports IT equipment, motors, and control panels. DOE 2016 efficiency and UL listing help meet regulatory and enterprise sustainability goals, while the RH5 weathershield and CASE D enclosure support flexible indoor/outdoor placement as needed.
The transformer complies with DOE 2016 Efficient requirements, UL Listed certification, and 10 CFR Part 431 Efficient standards. These certifications reduce regulatory risk, simplify procurement for regulated facilities, and support long-term energy performance guarantees. The combination of CASE D/NEMA 1 enclosure and RH5 weather protection broadens installation options across plant environments.
K-Factor nonlinear design improves energy efficiency and reduces standby and load losses, directly lowering operating costs. Aluminum windings offer corrosion resistance and easier handling, which simplifies installation and maintenance. With resilient insulation and robust cooling margins, the transformer delivers longer service life and lower risk of unexpected downtime, contributing to a favorable total cost of ownership across asset life.
