FAQs
Yes. The S48D11S15N is a single-phase transformer with a 480 V primary and 120/240 V secondary, designed for standard control panels and distribution setups. It supports 60 Hz operation and 16A wiring, making it straightforward to integrate into existing electrical architectures without extensive panel redesigns.
Leverage the NEMA 3R enclosure for indoor-outdoor protection, ensuring adequate clearance and ventilation around the unit. Verify that mounting allows for proper heat dissipation, access to taps, and ease of wiring. The UL Listed rating helps satisfy safety requirements for outdoor installations and reduces commissioning risk.
The transformer provides four tap settings: 2 at +2.5% FCAN and 2 at -2.5% FCBN. These taps enable precise voltage regulation to accommodate nominal fluctuations in supply voltage, minimizing overvoltage or undervoltage conditions in sensitive loads.
The unit is UL Listed, indicating adherence to recognized safety standards. It carries Eaton’s warranty policy, typically one year from installation or eighteen months from shipment, whichever occurs first, providing coverage for manufacturing defects and performance issues under normal use.
Yes. With a 15 kVA rating, 480 V primary, 120/240 V secondary, aluminum coil, and a compact footprint, it fits standard panel boards and retrofits.
