FAQs
The unit is designed with an EP encapsulated design and a NEMA 3R enclosure, making it suitable for indoor-outdoor use. Its 240/480 V primary and 120/240 V secondary in a single-phase, 60 Hz configuration supports standard control panels, OEM equipment, and machine controls. Mounting should follow manufacturer guidelines for safe enclosure clearance and ventilation.
With a 15 kVA rating, the transformer handles standard control loads and machinery power needs without overheated operation. Copper windings improve efficiency and thermal performance, while the 115 °C rise specification helps predict temperature management in panel environments. This translates to stable voltage conversion and reduced risk of nuisance tripping during peak startup conditions.
Yes. The transformer features a low sound profile of 47 dB and a NEMA 3R enclosure suitable for indoor-outdoor service. The combination of encapsulation and rugged enclosure reduces wind, dust, and moisture ingress, making it appropriate for spaces where noise and environmental exposure are concerns.
The unit is UL Listed, providing recognized safety certification for electrical components. The design supports weather-resilient operation with a NEMA 3R enclosure configuration. This combination helps meet common electrical codes for commercial and industrial installations and streamlines compliance during inspections.
Encapsulated copper windings with a robust enclosure reduce moisture ingress and dust exposure, lowering maintenance needs and downtime. The compact footprint simplifies installation, saving panel space and labor costs. Over the transformer’s life, these factors contribute to improved uptime, predictable power delivery, and lower total cost of ownership in manufacturing and automation environments.
