Eaton MD75E97 Motor drive isolation ventilated transformer - UL Listed
Part Number: MD75E97
Quick Summary
The Eaton MD75E97 motor drive isolation ventilated transformer provides clean, isolated power for drive systems in industrial automation applications. Engineers often battle voltage transients, know-how gaps, and downtime that erode productivity and increase maintenance costs. UL Listed certification supports electrical safety and quick panel integration, while the DT-3 dry-type design minimizes cooling needs. This transformer delivers reliable, scalable power for three-phase drive systems, offering compatibility with 575 V to 480 V applications and industry-standard frames. With a 75 kVA rating, it supports medium-duty drive loads and provides headroom for startup transients. Ventilated construction simplifies cooling in enclosed spaces, while the WS39 weather shield helps withstand industrial dust and moisture. With standard taps at +5% and -5% for easy voltage matching, installation remains straightforward for mixed-system environments.

FAQs
Plan for the DT-3 dry-type design with adequate ventilation and clearance around the 22 inch depth, 29 inch width, and 39 inch height. The WS39 weather shield helps in dusty environments, and the 914D frame requires mounting supports capable of handling 526 lb. Ensure 60 Hz three-phase power is available and use the +5% / -5% taps for voltage matching.
The unit provides a 575 V primary and 480 V secondary. It includes taps at +5% FCAN and -5% FCBN to accommodate modest voltage fluctuations typical in industrial networks, enabling smoother drive operation and reduced transients when connected to mixed-power systems.
Yes. It features a 150°C rise specification and ventilated cooling within a robust enclosure. The WS39 weather shield further protects windings from dust and moisture, making it suitable for moderately harsh environments commonly found in manufacturing floors and outdoor-rated panels.
The MD75E97 is UL Listed, supporting electrical safety and compliant panel integration. It is backed by Eaton’s standard warranty policy, offering one year from installation or eighteen months from shipment, whichever occurs first, to help manage maintenance planning and ROI projections.
By delivering clean, isolated power with a dedicated drive isolation function, the transformer reduces transient energy reaching drives, lowering fault rates and downtime. The 75 kVA rating provides headroom for startup surges, while the ventilated dry-type design minimizes cooling needs and energy waste, contributing to lower operating costs over the asset life.
