FAQs
This transformer supports indoor-outdoor service in industrial control panels thanks to a NEMA 3R enclosure. It is single-phase, 60 Hz with primary 120 V or 240 V and secondary 12/24 V, rated at 0.1 kVA. It weighs about 7 lb and fits a 4 in x 4.11 in x 8.5 in footprint with 3B wiring.
Key specs include 60 Hz frequency, single-phase operation, 0.1 kVA VA rating, primary 120/240 V, secondary 12/24 V, 115 °C rise, aluminum coil, EP design, and a NEMA 3R enclosure. It is UL Listed and suitable for 60 Hz systems, ensuring predictable voltage conversion and thermal margin in automation equipment.
Yes. The NEMA 3R enclosure and indoor-outdoor rating make it appropriate for exterior-mounted or damp locations. Its rugged aluminum coil and compact footprint simplify mounting in tight panels. The buck-boost capability allows on-site voltage adjustment to match equipment ratings, reducing the need for separate boosters and minimizing wiring runs.
The S10N04A82N is UL Listed, indicating compliance with safety standards. Eaton offers a one-year warranty from installation or eighteen months from shipment, whichever occurs first. This warranty supports maintenance planning and provides assurance against manufacturing defects, helping procurement manage risk in automation projects.
By delivering 0.1 kVA from a compact 120/240 V primary to 12/24 V secondary, it reduces panel space, minimizes wiring, and lowers inventory needs. The buck-boost function mitigates voltage mismatch losses in mixed-voltage installations, improving uptime in automation lines and lowering total cost of ownership over the equipment lifecycle.
