FAQs
This is a dry-type, three-phase transformer with a 200X wiring connection and copper windings. Connect the primary to your 480 V three-phase supply and the secondary to 208Y/120 V loads. Utilize the available taps (+2.5% and -2.5%) to fine-tune voltage under load. Ensure compliance with 60 Hz operation, maintain proper clearance for heat dissipation, and verify the 115 °C rise rating in the installation environment.
The unit provides a 45 kVA rating at 60 Hz in a three-phase configuration with a 15° phase shift. Copper windings support low losses and robust thermal performance, while the pork stability comes from UL Listing and NEMA TP-1 efficiency. These attributes collectively reduce harmonics and improve equipment reliability in drive-intensive applications.
Yes. Its harmonic-mitigation design helps manage inverter-generated harmonics common in PV systems and data centers. With a 480 V primary and 208Y/120 V secondary, it matches typical PV balance-of-system or IT load distribution. UL Listed and NEMA TP-1 efficient ratings further support compliance, while WS39 weather shield compatibility broadens outdoor applicability.
The X48M28F45TCUEEPOS is UL Listed and NEMA TP-1 compliant, matching industry safety and efficiency standards. It is designed for reliable operation with a 115 °C rise rating, three-phase 60 Hz operation, and copper windings. These certifications simplify procurement, testing, and regulatory approval for industrial installations.
The transformer’s copper windings and thermal indicator support durable operation with lower resistive losses and proactive temperature monitoring, which reduces unplanned downtime. Harmonic mitigation lowers drive-related heating, potentially extending motor life and reducing maintenance costs. Combined with UL/NEMA TP-1 compliance, this unit delivers improved ROI for continuous-process environments.
