FAQs
Install by mounting the unit in a suitable enclosure or panel, connect the 480 V primary to the supplied 3-phase or single-phase connections per code, and wire the 120/240 V secondary outputs to the downstream loads. Use the two +2.5% and four -2.5% taps to fine-tune voltage under load, follow insulation and clearance guidelines, and consider the WS11 weather shield for outdoor use.
Key specs include 15 kVA, 60 Hz operation, 480 V primary, 120/240 V secondary, single-phase configuration, and aluminum coil with frame 816. The 150°C rise indicates robust thermal tolerance under full load, enabling stable operation in demanding environments and ensuring reliability in continuous duty within automation systems.
Yes. UL Listed certification confirms safety and conformity, while NEMA TP-1 compliance and efficiency labeling support code-driven panel design. The optional WS11 weather shield expands outdoor applicability, making it suitable for harsh environments where rugged transformer performance and dependable power conditioning are required.
The transformer is UL Listed and NEMA TP-1 compliant, with NEMA TP-1 efficiency notes. These certifications help ensure safety, reliability, and energy-performance compliance for industrial power distribution and control systems, simplifying procurement approvals, audits, and installation in regulated environments.
With a one-year installation-based warranty (or 18 months from shipment) and robust construction, maintenance is typically minimal. Benefits include improved power quality, reduced downtime, energy efficiency, and a compact footprint for easier integration, all of which contribute to lower total cost of ownership in automation and manufacturing facilities.
