FAQs
Yes. The MV48M28F49CU is a three-phase marine-duty transformer with ABS certification and UL listing, designed for shipboard and offshore environments. It provides a 480 V primary to 208Y/120 V secondary, 60 Hz operation, and comes in a rugged NEMA 2 enclosure with WS19 weather protection, making it suitable for harsh maritime installations.
The unit delivers 150 kVA at 60 Hz with a 480 V primary and 208Y/120 V secondary. It features taps at 2 at +2.5% FCAN and 4 at -2.5% FCBN for voltage compensation, enabling stable output under input variations and load fluctuations typical of vessels and industrial sites.
The MV48M28F49CU is ABS certified and UL listed, ensuring compliance with maritime and electrical safety standards. These certifications help with regulatory approvals, insurance considerations, and reliability expectations on critical equipment used in ships, offshore platforms, and compliant industrial installations.
WS19 provides corrosion and weather resistance, while the NEMA 2 enclosure protects the windings from dust, moisture, and salt spray. Together, they extend service life in exposed coastal or deck-mounted locations and reduce maintenance cycles for offshore and outdoor industrial deployments.
With a 916A frame and 994 lb weight, the transformer fits standard mounting footprints and typical deck or equipment spaces. The 150 kVA rating supports consolidated power distribution, potentially reducing the number of transformers. Warranty spans one year from installation or 18 months from shipment, whichever comes first, aiding budgeting and asset management.
