FAQs
Plan for indoor or controlled-environment installation with adequate clearance for cooling and servicing. The unit uses a 918A frame, copper windings, and a 203X wiring connection, so verify panel spacing, mounting surface rigidity, and accessible wiring routes. Ensure ambient conditions stay within the dry-type rating and that protective enclosures and WS34 weather protection are considered if installed in semi-exposed spaces.
Key specs include three-phase operation at 60 Hz, 150 kVA rating, primary 480 V, secondary 208Y/120 V, and a -30° phase shift with voltage taps of +2.5% and -2.5%. Copper windings provide high conductivity and cooling efficiency, while NEMA TP-1 compliance and UL listing ensure safety and performance under harmonic loading conditions common in automated facilities.
Yes. Its 150 kVA rating, precise voltage regulation, and harmonic mitigation capabilities make it suitable for data centers and manufacturing lines where clean power, voltage stability, and minimized harmonic impact are critical for reliability and equipment life.
The unit is UL Listed and NEMA TP-1 Compliant, with NEMA TP-1 efficient catalog notes. These certifications confirm adherence to safety, performance, and efficiency standards, which simplifies compliance documentation, reduces commissioning risk, and supports energy-management initiatives.
Copper windings and dry-type construction reduce maintenance needs compared with oil-filled designs, while the 80 °C rise and robust 918A frame support long service life in busy facilities. Plan periodic inspections of cooling paths, verify tap positions during commissioning, and schedule preventive checks aligned with equipment hit-rate to maximize ROI.
