Eaton S48D11S01LS42 General-Purpose Encapsulated Transformer - UL Listed
Part Number: S48D11S01LS42
Quick Summary
Eaton S48D11S01LS42 is a general purpose encapsulated transformer for control panels and equipment racks. Engineers seek dependable, quiet, and compact power conversion that fits tight enclosures and varied input voltages. This unit meets those needs with low sound output, a weather-ready NEMA 3R enclosure for indoor-outdoor installations, and UL Listed certification for compliance. The transformer uses aluminum windings and a robust 1 kVA rating to handle short-term peaks in automation workloads. By pairing a 480 V primary with a 120/240 V secondary, it supports common industrial loads while maintaining energy efficiency. This combination reduces panel space, simplifies procurement, and streamlines maintenance across secondary systems.

Feature: General specifications and encapsulated design. The unit’s sealed encapsulation and NEMA 3R enclosure minimize exposure to dust and moisture, enabling dependable operation in mixed indoor-outdoor environments. Business impact: Longer service life reduces downtime and maintenance costs. Application: Control panels and automation enclosures in manufacturing lines benefit from reliable, maintenance-friendly power conversion. Feature: Aluminum coil construction. Aluminum windings lower weight and material cost while preserving thermal performance. Business impact: Easier handling during installation and reduced shipping expenses. Application: Retrofit or new installations where weight and space are at a premium in machine houses and control cabinets. Feature: Tap settings for voltage fine-tuning. With 2 taps at +2.5% FCAN and 2 taps at -2.5% FCBN, voltage can be trimmed to match site conditions. Business impact: Improved regulation and reduced risk of downstream equipment instability. Application: Automated systems requiring tight voltage control in variable supply environments. Feature: 1 kVA rating at 480 V to 120/240 V. Business impact: Sufficient power for PLCs, relays, sensors, and control electronics with headroom for short-term spikes. Application: Powering automation modules in conveyors, presses, and process equipment. Feature: Low noise and rugged reliability. Catalog notes indicate 42 dB sound output and indoor-outdoor capability. Business impact: Quiet operation supports workplace comfort and permits panel proximity to operators. Application: Machines near workstations and process lines where noise containment matters.

FAQs
Install within a suitable enclosure rated for indoor-outdoor use, ensuring adequate clearance for wiring and cooling. The unit dimensions are 5.75 in (L) x 5.99 in (W) x 11.28 in (H) with a weight of ~28 lb, so provide mounting hardware and space for 16 A wiring connections. Maintain manufacturer-recommended ventilation to prevent heat buildup during peak loads.
The transformer features taps at +2.5% FCAN and -2.5% FCBN, allowing precise adjustments to loading conditions. The primary is 480 V with a 120/240 V secondary, designed for 60 Hz operation. Typical tolerance targets are ±2.5%, enabling stable voltages for sensitive automation equipment and reducing the risk of nuisance tripping in PLC inputs.
Yes. The unit is designed with a NEMA 3R enclosure and an indoor-outdoor rating, supporting operation in varied humidity and dust conditions. UL Listed certification further confirms compliance for rugged industrial installations. When mounted outdoors, provide protection from direct exposure to severe weather and ensure adequate ventilation for thermal management.
Ideal for control panels powering PLCs, relays, and sensors, the 1 kVA, 480 V to 120/240 V configuration supports distributed power in conveyors, machine tools, and process lines. Its low-noise profile of 42 dB and lightweight aluminum windings simplify relocation or retrofits, while the ±voltage taps help maintain stable operation across fluctuating supply conditions.
The unit carries Eaton’s standard warranty policy (25-000), typically one year from installation or eighteen months from shipment, whichever comes first. UL Listed certification aids compliance and procurement approvals.
