FAQs
MV48M28F75CU is designed for marine and industrial power distribution, delivering 480 V primary to 208Y/120 V secondary at 75 kVA. It uses copper windings, a 915D frame, NEMA 2 enclosure, and WS39 weather shield, making it suitable for shipboard panels, offshore equipment rooms, and rugged outdoor installations. It accepts taps for voltage adjustment to maintain stability under changing loads.
This transformer is ABS Certified and UL Listed, ensuring compliance with maritime and electrical safety standards. The combination supports regulatory acceptance in shipping, offshore platforms, and heavy industrial facilities, reducing procurement risk and accelerating approval cycles for projects requiring formal verification of safety and reliability.
Key specs include 75 kVA rating, primary 480 V, secondary 208Y/120 V, 60 Hz frequency, copper windings, and a 22 in length by 39 in height by 29 in width frame 915D. It also features voltage taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN, with WS39 weather shield and NEMA 2 enclosure for protection in harsh environments.
The taps allow ±2.5% adjustments to the primary voltage, enabling fine-tuned output under fluctuating supply conditions or load changes. This reduces regulator cycling, minimizes voltage drop and equipment stress, and helps maintain consistent performance for critical loads such as propulsion controls, pumps, and onboard electrical systems.
The transformer carries Eaton’s warranty of one year from installation or eighteen months from shipment, whichever comes first. Durable copper windings, NEMA 2 enclosure, and WS39 shield contribute to lower maintenance needs. For ongoing reliability, ensure regular inspection of enclosure integrity, tap settings, and cooling pathways in accordance with standard marine electrical maintenance practices.
