FAQs
Yes. The S48D27S10CU delivers 480 V primary to 277 V secondary in a single-phase configuration, with copper windings and a 10 kVA rating, making it suitable for control panels, motor starters, and PLC power domains. Its taps (+2.5% FCAN, -2.5% FCBN) support voltage fine-tuning during installation and commissioning.
The transformer provides two taps at +2.5% FCAN and two taps at -2.5% FCBN, enabling precise voltage regulation under varying loads. Expect tight regulation for sensitive automation equipment, reducing nuisance tripping and improving performance of downstream devices in panel boards and machine controls.
This 10 kVA encapsulated transformer is well-suited for industrial control panels, machine automation cabinets, and outdoor indoor installations requiring reliable single-phase power conversion. Its compact 179 frame, NEMA 3R enclosure, and UL Listed certification support rapid deployment in OEM builds and retrofit projects with space or environmental constraints.
The S48D27S10CU carries UL Listed safety certification, confirming compliance with recognized safety standards. Its NEMA 3R enclosure rating additionally documents protection for indoor-outdoor use against moisture and dust. Together with copper windings and documented specifications, these attributes simplify supplier qualification and customer audits.
Maintenance is typically straightforward: monitor insulation integrity and temperature, inspect cooling paths, and verify tap connections during periodic checks. The 10 kVA, copper-wound design offers robust reliability, reducing downtime and extending service life. ROI improves through reduced field failures, faster installation, and fewer parts replacements in power-distribution panels.
