The S48D11P16CU is a general-purpose encapsulated transformer rated at 1.5 kVA, designed for single-phase 60 Hz operation with a 480 V primary and 120/240 V secondary. Feature → Business Impact → Application: Copper windings and EP encapsulation improve moisture resistance and thermal stability, delivering reliable power with lower maintenance in automation gear and control panels. This translates to fewer field failures and longer service life in busy manufacturing lines. Feature → Enclosure and environmental resilience: a NEMA 3R indoor-outdoor enclosure and Weathershield construction enable outdoor mounting in damp or dusty environments, reducing protection retrofit costs and enabling flexible panel layouts in warehouses or outdoor equipment rooms. Feature → Voltage regulation: dual taps (+2.5% FCAN and -2.5% FCBN) allow precise output adjustment to maintain equipment performance, minimizing nuisance tripping in variable utility conditions. Feature → Installation and footprint: compact dimensions (6.56 in L, 5.53 in W, 13.03 in H) and 31 lb weight simplify mounting and service accessibility, improving field install times and reducing labor costs. Feature → Reliability and warranty: UL Listed safety certification, 60 Hz operation, and a one-year warranty (or eighteen months from shipment) provide regulatory compliance confidence and total-cost-of-ownership benefits for panel builders and maintenance teams.

FAQs
Begin by mounting the unit in a NEMA 3R rated enclosure or protected panel area. Connect the primary terminals to a 480 V supply and the secondary to the 120/240 V loads. Set the dual voltage taps to +2.5% FCAN and -2.5% FCBN as required by your system to optimize voltage regulation and protect connected equipment. Verify clearance and wiring per applicable codes.
The transformer features a 480 V primary and a 120/240 V secondary, with a rated volt-ampere (VA) of 1.5 kVA. It operates at 60 Hz and is designed for single-phase service, making it suitable for control panels, PLCs, and automation circuits requiring stepped-down voltage with stable regulation.
Yes. The S48D11P16CU uses a NEMA 3R enclosure suitable for indoor-outdoor installations, and its EP encapsulated copper-wound design provides moisture and temperature resilience. Weathershield construction further supports outdoor applications, reducing the need for additional weatherproofing in harsh environments.
This Eaton transformer is UL Listed, confirming safety compliance for electrical systems. It carries a warranty of one year from installation or eighteen months from shipment, whichever occurs first, offering protection against manufacturing defects and supporting TCO planning for panel builders and maintenance teams.
Ensure proper tap settings (+2.5% FCAN and -2.5% FCBN) to maintain voltage under supply variation. Use copper windings with epoxy encapsulation to resist moisture and heat, and place the unit in a ventilated, accessible area to monitor temperature rise (115 C). The unit’s compact footprint and accessible wiring simplify service and upgrades without compromising performance.
