Copper windings deliver excellent conductivity and thermal performance, reducing losses and extending transformer life, which translates into lower operating costs and improved reliability in mission-critical marine and industrial applications. The 50 kVA rating at 60 Hz ensures ample headroom for motors, controls, and lighting without oversizing, helping site engineers optimize space and reduce capital expenditure. With primary 240/480 V input and 120/240 V output plus taps (+5%, -5%, +2.5%, -2.5%), voltage regulation improves downstream equipment protection and process stability, even under utility swings. The NEMA 2 enclosure provides dependable indoor protection, while optional WS16 Weathershield enhances outdoor or harsh environments common on vessels and offshore platforms. UL Listed and ABS Certified compliance facilitates installation approvals, while NEMA TP-1 efficiency notes support energy-conscious procurement. Compatibility with common 60 Hz electrical infrastructure enables straightforward retrofits and faster project deployments, improving total cost of ownership through easier maintenance and longer service life.
