FAQs
For installing the N48M47F22EE, ensure proper panel mounting with adequate clearance for ventilation and access to tap settings. Verify 480 V three-phase connections and 480Y/277 V secondary wiring, maintain stable grounding, and comply with UL Listed installation practices. Provide suitable enclosure protection and wind-down time during startup to minimize transient surges and thermal stress.
The two positive and four negative tap settings allow fine-tuning of output voltage under fluctuating loads. In practice, shifting taps helps counteract voltage drop along long feeders or varying primary voltages, stabilizing downstream equipment and reducing flicker in sensitive controls. Proper tap management during commissioning can reduce nuisance tripping and improve drive performance.
Yes. With a 225 kVA rating, 480 V primary, and 480Y/277 V secondary, the N48M47F22EE is well-suited for data centers requiring reliable three-phase distribution. Its K-Factor nonlinear design mitigates harmonics from non-linear IT loads, while UL listing and NEMA TP-1 efficiency support compliance, cooling efficiency, and long-term operational stability.
The transformer carries UL Listed certification and NEMA TP-1 compliance, with NEMA TP-1 efficient designation. These certifications reduce procurement risk, simplify audits, and ensure performance under standard industry conditions. The 115°C rise rating further confirms reliability in demanding environments, enabling compliant integration into industrial automation and distribution schemes.
Expect a favorable ROI from improved energy efficiency, reduced cooling loads, and lower maintenance due to the 115°C rise rating and robust electrostatic shielding. The aluminum windings and durable construction minimize copper costs and downtime. Regular maintenance focuses on tap position checks, insulation integrity, and connection torque to sustain peak performance over years.
