FAQs
Plan for a dedicated, properly ventilated indoor or weather-protected space to accommodate the 75 inch height and 44.2 inch width of the 919X frame. Ensure 203X wiring connections are accessible and that clearances meet manufacturer guidelines. The WS35 weather shield option supports outdoor or semi-outdoor siting, while embedded thermal indicators enable proactive fault detection during commissioning.
The harmonic mitigating design targets distortion sources at the source, improving overall power quality. With 480 V primary and 400Y/231 V secondary, 60 Hz three-phase operation, and a -30° phase shift, the unit stabilizes voltage, reduces circulating currents, and lowers losses associated with harmonics. Expect fewer trips, steadier voltage, and improved equipment life for harmonic-rich loads.
Yes. The 350 kVA dry-type transformer with copper windings, precise tap changes, and NEMA TP-1 efficiency design is well-suited for PV integration and data centers where harmonic management and reliable power delivery are critical. The 480 V to 400Y/231 V transformation supports mixed-load facilities, enabling stable operation for diverse equipment palettes.
UL Listed confirms adherence to safety and performance standards, while NEMA TP-1 compliance verifies efficiency and suitability for commercial power distribution. For specifiers and inspectors, these certifications reduce risk, streamline procurement, and ensure consistent performance in regulated industrial environments.
Maintenance focuses on validating insulation integrity, thermal indicators, and connection torque. The embedded center-coil indicators and robust frame reduce downtime risk, contributing to lower maintenance costs and longer service life. ROI comes from improved power quality, reduced energy losses, and fewer outages in high-demand facilities.
