FAQs
Aim to place the unit in a clean, ventilated indoor space with level flooring and adequate clearance for service access. The transformer is three-phase 480Y/277 and weighs 658 lb, so plan for a suitable rigid mounting pad and proper hoisting equipment during installation. Refer to the downloadable specification sheet for mounting feet and clearance requirements; UL Listed status supports compliant commissioning.
Yes. The N48M28F4521LS50 uses a K-Factor nonlinear design to mitigate harmonic distortion, improving power quality and reducing stress on downstream equipment. This makes it particularly appropriate for facilities with nonlinear loads such as switching power supplies, drives, and high-efficiency motors.
The unit is UL Listed, indicating fundamental safety compliance. Specific CE, IP ratings, or SIL certifications are not listed in the product data provided; verify site requirements with your engineering team and consult the Eaton datasheet to determine if additional certifications are available or required for your installation.
The transformer footprint is 24 inches in length, 30.5 inches in width, and 36.88 inches in height, with an approximate weight of 658 pounds. Use these figures for rack, foundation, and room-occupancy planning, ensuring adequate access for maintenance and possible vibration dampening where needed.
