FAQs
Installation should be performed indoors within a NEMA 2 enclosure environment, with proper clearance for cooling. Use the 283B winding connection and plan for tap adjustments (+2.5% or -2.5%) to compensate voltage drop along feeders. The unit supports a 60 Hz supply and requires appropriate overcurrent protection and proper mounting to minimize vibration and noise transmission.
The K-Factor nonlinear design mitigates harmonics and thermal stress in high-load, variable-power applications, improving voltage regulation and efficiency. This translates to reduced transformer heating, longer component life, and improved availability of critical drives and PLCs in automated lines, while maintaining compliance with typical industrial power standards.
Yes. The N48M28T30EESRLS43 is UL Listed and equipped with a NEMA 2 enclosure for indoor use. It also features a low-noise design (~43 dB) and a certified NEMA ST-20 test report, ensuring compliance with common industrial safety and performance requirements in manufacturing and process environments.
The transformer provides two taps at +2.5% and four taps at -2.5%, enabling voltage regulation to maintain output near 208Y/120 V under voltage drop or spike conditions. This flexibility supports sensitive equipment like drives, controllers, and sensors, reducing the risk of misoperation due to voltage fluctuation.
With robust insulation (150 °C rise, 200°C insulation), aluminum coil construction, and an electrostatically shielded design, maintenance intervals are extended and diagnostic clarity improves. The combination of UL Listing, low noise, and efficient operation minimizes energy waste, delivering a favorable total cost of ownership through longer service life and reduced downtime in automation applications.
