Eaton MD75E99 Drive-Isolation Ventilated Transformer - 150C
Part Number: MD75E99
Quick Summary
Eaton MD75E99 drive isolation ventilated transformer delivers motor drive isolation and cooling for industrial power systems. Engineers confront overheating, voltage fluctuations, and EMI when integrating motor drives, driving maintenance costs and downtime. Certifications typically include CE marking, SIL readiness, and IP protection; this MD75E99 lists certifications as 'Contact Manufacturer', so confirm during procurement. Designed for 75 kVA drive isolation with 3-phase 480 V delta connections, it supports reliable plant power and predictable service. For panel builders and OEMs, the ventilated design enhances cooling efficiency, reduces enclosure heat rise, and simplifies installation with standard 480 V delta inputs. This combination supports uptime, safety, and long-term total cost of ownership.
