FAQs
The N29M28T1516OS features a floor or wall mounting option, offering flexible installation in constrained or crowded electrical spaces. This enables easier retrofits and layout optimization in control rooms, mechanical spaces, or data center enclosures while maintaining accessibility for maintenance.
The transformer is designed for a 208 V primary input and provides a 208Y/120 V secondary output. This configuration supports typical three‑phase utility feeds and common 120 V control circuits found in industrial automation panels.
Yes. The unit is UL Listed and complies with DOE 2016 efficiency requirements, ensuring energy performance, reliability, and regulatory alignment for commercial and industrial installations.
Modification notes indicate an electrostatic shield with OSHPD approval. OSHPD approval supports use in facilities subject to California hospital and health system regulations, reducing project risk where regulatory compliance and traceability are critical.
With DOE 2016 efficiency and an aluminum winding design, the transformer delivers lower no-load and load losses compared to older models. While ROI depends on site loads and utility incentives, energy savings over the service life typically improve total cost of ownership for facilities with continuous or high-throughput power needs.
