S48D11E01CU Eaton General-Purpose Transformer UL Listed
Part Number: S48D11E01CU
Quick Summary
S48D11E01CU Eaton general-purpose transformer provides reliable power isolation and voltage transformation for control panels. When voltage stability matters, fluctuations can cause misoperation, nuisance trips, and downtime that ripple through the line. This unit carries UL Listed certification and a rugged NEMA 3R enclosure, plus copper windings designed for durable, efficient operation in mixed indoor-outdoor environments. With a 1 kVA rating, single-phase 480 V primary and 120/240 V secondary, it accommodates diverse control circuits and auxiliary loads, while 2 at +2.5% and 2 at -2.5% taps help maintain voltage accuracy under supply variance. Ideal for industrial cabinets, panel builders, and retrofit projects seeking reliable, compact voltage transformation with sustainable performance.

Feature: Copper windings and epoxy encapsulation deliver robust electrical performance and moisture resistance. Business Impact: Copper windings minimize resistive losses and improve thermal efficiency, reducing energy waste and extending transformer life in demanding environments. Application: ideal for control panels and industrial cabinets where heat build-up is a concern. Feature: NEMA 3R enclosure design with indoor-outdoor capability and electrostatic shielding. Business Impact: enables safe outdoor or semi-exposed installations without extra housing, lowering total installed cost and protection risk. Application: panel rooms near docks, outdoors, or bays where weather exposure is possible. Feature: Tap changes at 2 at +2.5% FCAN and 2 at -2.5% FCBN. Business Impact: improves voltage regulation under fluctuating supply, reducing nuisance trips and preserving sensitive electronics. Application: critical automation circuits and instrumentation that require stable secondary voltage. Feature: 1 kVA single-phase rating with primary 480 V and secondary 120/240 V. Business Impact: supports multiple control circuits from a single unit, reducing component count and space needs while simplifying wiring. Application: small to mid-size control panels and machine infeed sections. Feature: 60 Hz operation and 115 °C rise specification. Business Impact: reliable performance in typical North American facilities with respectable thermal margins, lowering risk of thermal shutdowns. Application: continuous-duty installations in busy electrical rooms. Feature: UL Listed certification and compact footprint (5.75 in D × 5.99 in W × 11.28 in H; 28 lb). Business Impact: simplifies procurement and installation with recognized safety approval and a space-conscious footprint. Application: retrofit projects and new cabinet builds where space is at a premium.

FAQs
The S48D11E01CU is designed for indoor-outdoor use in control panels and compact electrical cabinets. Its NEMA 3R enclosure provides weather resistance suitable for exposed environments, and its dimensions (11.28 in height, 5.99 in width, 5.75 in depth) support common panel layouts. Mounting typically uses standard hardware in panel enclosures, with proper clearance for ventilation and service access.
Key specs include a 1 kVA rating, single-phase, primary voltage of 480 V, secondary voltage of 120/240 V, and 60 Hz operation. It features copper windings, an epoxy encapsulated design, and a 115 °C rise rating. Tap connections are 2 taps at +2.5% FCAN and 2 taps at -2.5% FCBN to aid voltage regulation.
Industrial automation, control panels, and retrofit projects benefit most. The unit provides reliable voltage conversion for auxiliary loads and instrumentation, supports compact layouts in panel builders, and offers rugged performance in mixed indoor-outdoor environments. It is well-suited for small to mid-size machinery and machine control applications needing stable 480 V to 120/240 V distribution.
UL Listed indicates the transformer has been tested for safety and reliability to applicable standards, simplifying procurement and compliance in regulated environments. While the unit emphasizes UL certification, ensure installation follows local electrical codes and manufacturer guidelines for enclosure protection, clearances, and thermal management, especially in outdoor or semi-exposed locations.
The product is covered under Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance includes visual inspection, connection checks, and ensuring that the enclosure remains weather-protected and free of dust. Regular checks help sustain efficiency and minimize unplanned downtime in automated lines.
