FAQs
The S10N04A07N is designed for indoor-outdoor use thanks to its NEMA 3R enclosure, enabling placement in control cabinets, outdoor boxes, or process areas exposed to dust and moisture. It delivers a robust 7.5 kVA, single-phase service with aluminum windings, suitable for automation panels and equipment that require stable power under fluctuating loads.
The transformer supports 120 V or 240 V primary input and provides a 12/24 V secondary output. With a 60 Hz single-phase design and a 7.5 kVA rating, it is well-suited for driving low-voltage control circuits, sensors, and solenoids from standard plant power while accommodating voltage variations in industrial environments.
Yes, it is a buck-boost general-purpose encapsulated transformer designed to stabilize voltage for automation equipment. Typical applications include control panels, machine controls, and distributed power systems where maintaining consistent voltage improves PLC reliability and minimizes nuisance trips during upstream supply fluctuations.
The unit is UL Listed and features a NEMA 3R enclosure, enabling indoor-outdoor use. These certifications and ratings help engineers meet regulatory requirements and ensure safe operation in both protected indoor environments and harsher outdoor installations, without needing additional protective enclosures.
Eaton’s policy provides a one-year warranty from the date of installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on the rugged NEMA 3R enclosure, aluminum windings, and compact encapsulated design to minimize field servicing, support longer service intervals, and reduce unexpected downtime in continuous operation.
