FAQs
The S29D48S15SS uses a 582F wiring connection and is designed for a compact 180 frame, enabling straightforward panel mounting. Its UL Listed construction and NEMA 3R enclosure support indoor-outdoor installations, while the +2.5% and -2.5% taps allow on-site voltage adjustment. This combination reduces commissioning time and minimizes field rewiring costs during retrofits.
With two taps at +2.5% FCAN and two taps at -2.5% FCBN, the transformer offers precise secondary voltage regulation under varying load and input conditions. This helps prevent undervoltage or overvoltage scenarios for PLCs, drives, and sensors, improving control accuracy, reducing nuisance trips, and extending upstream equipment life during peak start-up or fluctuating supply events.
Yes. The S29D48S15SS features a NEMA 3R enclosure option and an indoor-outdoor Weathershield configuration, making it appropriate for damp or outdoor locations. The Grade 304 stainless steel catalog note further enhances corrosion resistance, reducing maintenance cycles and replacement costs in harsh environments such as loading docks, exterior switchgear, or exposed control rooms.
The transformer is UL Listed, which supports compliance with widely adopted safety standards. Its rugged enclosure and corrosion-resistant construction align with industrial reliability expectations. While CE or IP ratings aren’t specified in the data, UL certification and NEMA 3R enclosure provide a clear pathway for regulatory acceptance in many facilities and for procurement requirements.
The 15 kVA, 60 Hz, single-phase design paired with aluminum coil and encapsulated EP construction delivers high reliability and reduced heat-related wear. The UL Listing, corrosion resistance, and warranty support predictable maintenance budgets and lower downtime. Over the life of a distribution system, these factors translate to lower total cost of ownership and faster project payback in busy industrial plants.
