FAQs
MV48M22F49CU is designed for standard three-phase marine power distribution, featuring a 480 V primary and 240/120 V secondary suitable for common shipboard panelboards. The unit’s voltage taps (+2.5% FCAN and -2.5% FCBN) support on-site regulation to maintain stable loads across propulsion, lighting, and critical systems. Ensure panel clearance and mounting align with the frame 916A footprint for a clean integration.
The transformer is UL Listed and ABS Certified, confirming compliance with electrical safety and marine regulatory requirements. These certifications support risk mitigation in shipbuilding and retrofit projects, helping procurement meet safety standards and reducing the need for additional third-party testing.
Yes. The unit features a WS19 weather shield and a NEMA 2 enclosure, providing protection against dust, humidity, and moisture in engine rooms and outdoor locations. This rugged enclosure, combined with copper windings and robust frame construction, supports reliable operation in challenging marine environments.
With a footprint around 28 in (width) by 23 in (depth) by 48.6 in (height) and a weight near 860 lb, plan for a dedicated electrical room or reinforced mounting surface. Allow sufficient clearance for maintenance, cooling, and cable routing, and consider alignment with standard 60 Hz distribution systems to minimize integration work.
The MV48M22F49CU delivers predictable performance with copper windings and a proven marine-grade enclosure, reducing losses and downtime. The 150 kVA rating supports scalable loads, enabling efficient energy distribution and lower maintenance costs over time. The one-year warranty (or 18 months from shipment) provides lifecycle risk mitigation during procurement.
