FAQs
For installation, ensure proper mounting with adequate clearance for cooling in a ventilated enclosure. Connect the 480 V primary and 480Y/277 V secondary according to the nameplate. Use the taps at +2.5% and -2.5% to fine-tune voltage under load. Verify UL Listed and NEMA TP-1 compliance in the panel design, and budget for EMI shielding where nearby drives are present.
The N48M47B30EE offers a K-Factor nonlinear design with an 80 °C rise, delivering solid voltage regulation under varying loads. With aluminum windings and ventilated cooling, losses are reduced and efficiency is maintained across duty cycles. This translates to lower cooling requirements and improved energy performance for continuous operation in automation systems.
