FAQs
The transformer uses a compact frame 178 and a 538A wiring connection, with a NEMA 3R enclosure rated for indoor-outdoor use. Its dimensions (width 10.38 in, height 16 in, depth 9.89 in) support versatile mounting in panel closets, machine rooms, or exterior junctions. You can mount it on standard steel racks or dedicated panel supports, simplifying integration into existing electrical rooms.
Key specs include a 5 kVA VA rating, single-phase operation at 60 Hz, primary voltage options of 190–440 V, and a secondary of 110/220 V. The windings are aluminum, and the unit is designed for 115°C rise, which helps sustain performance under load while maintaining temperature limits in confined enclosures.
Yes. With UL Listed safety certification, NEMA 3R enclosure compatibility for indoor-outdoor use, and a 5 kVA rating, it is well-suited for control panels, PLC power feeds, drives, and automation cabinets in manufacturing and processing environments, delivering reliable, regulation-compliant power to essential equipment.
The transformer is UL Listed and features a NEMA 3R enclosure, enabling indoor and outdoor installation in compliant environments. The indoor-outdoor capability, combined with epoxy encapsulation, supports durability in varied conditions while meeting safety and reliability standards for industrial power distribution.
Aluminum windings and epoxy encapsulation enhance thermal performance and corrosion resistance, reducing drift under load and maintenance needs. The 115°C rise rating provides a healthy safety margin for continuous operation. A one-year warranty (or 18 months from shipment) further reduces total cost of ownership by guarding against field faults and performance degradation.
