Eaton Specification Sheet - N48M28F49EEOS
Feature: K-Factor nonlinear ventilated design reduces harmonic distortion and improves short-term fault tolerance. Benefit: Lower total harmonic distortion and improved equipment life, leading to fewer outages and better power quality for drives and PLCs in manufacturing lines. Application: Ideal for automation cabinets and motors with high harmonic content in data centers and heavy industry. Feature: Multiple taps (+2.5% and -2.5% with two +2.5% taps and four -2.5% taps). Benefit: Precise voltage regulation under load swings, reducing equipment stress and stabilizing control power. Application: Critical control panels and distributed load centers where voltage drift door-to-door must be minimized. Feature: 150 kVA rating with 480 V primary and 208Y/120 V secondary. Benefit: Sufficient headroom for mid-range industrial loads, enabling a compact footprint and fewer maintenance cycles. Application: Medium-scale manufacturing lines, machine tools, and automation zones requiring reliable step-down power. Feature: 115°C rise and ventilated design. Benefit: Enhanced cooling performance, longer transformer life, and reliable operation in warm environments. Application: Enclosures and plant rooms with higher ambient temperatures or dense cabinet installations. Feature: 3-phase KT-13 designation with compact integration into standard power distribution schemes. Benefit: Seamless compatibility with common electrical distributions and standard control power feeds. Application: Industry-standard power distribution in automation panels, switchgear rooms, and motor control centers. Industry insights: The N48M28F49EEOS aligns with Eaton’s transformer ecosystem, supporting ease of sourcing from Eaton catalogs and compatibility with the Transformer Flex Center approach for lifecycle management and service planning.

FAQs
Install the transformer in a dedicated, ventilated enclosure sized for the unit, connect the 480 V three-phase input to the primary lugs, and wire the 208Y/120 V secondary to the control circuits and panel feeders. Ensure proper tap selection (+2.5% or -2.5%) to maintain voltage within tolerance under varying load. Follow OEM guidelines for clearance, wiring practices, and protection coordination between upstream breakers and downstream protection.
The transformer employs K-Factor nonlinear design to mitigate harmonic currents, improving power quality for drives, regulators, and other non-linear loads. This reduces overheating risk, extends component life, and lowers maintenance costs while supporting compliant operation of sensitive equipment in automated lines.
Yes. With a 150 kVA rating and 480 V primary feeding 208Y/120 V secondary, the N48M28F49EEOS provides stable, isolated control power for PLCs, motor drives, and robotics in automation cabinets. Its voltage-tap options help regulate output during load changes, enhancing drive performance and reducing nuisance tripping in control circuits.
Certification notes indicate 'Contact Manufacturer' for current approvals and regional compliance. For projects with strict regulatory requirements, consult Eaton to confirm applicable safety, environmental, and electrical standards for your location and industry, and to obtain the necessary documentation and test reports.
Expect ROI from reduced maintenance due to improved reliability, lower harmonic-related losses, and fewer voltage-related outages in automation systems. The transformer's efficient cooling and regulated output minimize downtime and extend service intervals for mid-size loads, delivering lower lifecycle costs and improved system availability.
