FAQs
For compact control panels, ensure a clear space around the 9.89 in depth, 16 in height, and 10.38 in width, with room for electrical connections at 77B and proper ventilation for the 122 lb unit. The NEMA 3R enclosure provides weather resistance, but check local cabinet standards and mounting points to avoid obstruction of the 178 frame footprint.
The S29N29E07N is designed for 60 Hz, single-phase operation with a 208 V primary and 208 V secondary, delivering 7.5 kVA. This setup supports direct voltage matching in control circuits and machine interfaces, minimizing voltage translation losses and simplifying protection schemes in panel assemblies.
Yes. The unit features a NEMA 3R enclosure and indoor-outdoor weathershield, along with electrostatic shielding to mitigate EMI. These attributes make it appropriate for outdoor enclosures, damp locations, and spaces exposed to weather while maintaining reliability and safety.
The transformer is UL Listed, confirming compliance with essential safety standards. It also uses an epoxy-encapsulated construction with aluminum windings and a rugged NEMA 3R enclosure, aligning with common industrial and control-panel requirements in regulated environments.
Adopting the S29N29E07N can reduce downtime through robust weather resistance and EMI shielding, lower field service needs due to its rugged enclosure, and simplify procurement with UL certification. The 7.5 kVA rating supports scalable power distribution, potentially lowering total cost of ownership over time in automated lines.
