Eaton S48N27S02CU General-Purpose Transformer - UL Listed
Part Number: S48N27S02CU
Quick Summary
The Eaton General-Purpose Encapsulated Transformer delivers reliable, isolated power for control panels and automation equipment in demanding environments. This design addresses common field challenges such as moisture, dust, and space constraints by combining robust encapsulation with a compact footprint. UL Listed certification and a NEMA 3R enclosure support safe indoor-outdoor installation and code-compliant operation across diverse facilities. The primary rating of 480 V and secondary 277 V at 60 Hz makes it compatible with standard industrial power systems, while a 2 kVA rating provides ample headroom for load growth. In addition to performance, the copper windings and a 115 °C rise help minimize losses and extend service life, boosting overall equipment reliability and uptime.
