FAQs
Install in a ventilated enclosure with adequate clearance for 39 inch height and 29 inch width. Mount on a sturdy base compatible with the 914D frame, connect primary to 575 V three-phase supply, secondary to 230Y/133 V loads, and use the +5% and -5% voltage taps to adjust for feeder variations. Ensure UL Listed compliance and secure WS39 weather shield for protection in harsher environments.
The MD63E94 delivers 63 kVA at 575 V primary and 230Y/133 V secondary, 60 Hz, three-phase, with aluminum windings and a 150°C rise. This configuration isolates drive electronics from mains transients, reduces voltage spikes, and supports reliable operation of motor drives, improving uptime and reducing maintenance costs in heavy-duty applications.
Yes. With a 63 kVA rating and three-phase 575 V to 230Y/133 V distribution, the MD63E94 is well-suited for high-power servo drives and process equipment. Its dry-type DT-3 construction and ventilated WS39 shield enhance reliability in demanding environments, while voltage taps help manage feeder variations common in servo applications.
The transformer is UL Listed, ensuring compliance with safety standards essential for industrial installations. This certification, along with its dry-type design and inert insulation system, supports regulatory approvals, reduces risk during audits, and simplifies integration into compliant motor control centers and distribution panels.
By isolating drives from input disturbances, the transformer lowers nuisance tripping and motor wear, extending equipment life and reducing downtime. The rugged DT-3 design, WS39 shield, and reliable 63 kVA rating contribute to predictable performance, enabling faster maintenance planning and a clearer path to ROI through improved process reliability.
