FAQs
For panel installations, ensure the enclosure provides adequate clearances around the 912BN frame and allows heat dissipation without requiring active ventilation. The unit is a totally enclosed non-ventilated transformer, simplifying enclosure design and reducing ingress risk. Verify mounting in a suitable environment and use proper wiring practices for 480 V primary and 208Y/120 V secondary circuits.
The transformer delivers 15 kVA with a 480 V primary and 208Y/120 V secondary, providing safe, regulated control power for PLCs, drives, and instrumentation. Its DT-3 dry-type design reduces ventilation needs, while aluminum windings support efficient heat transfer. This combination improves reliability and simplifies integration with standard control panels and automation gear.
The dual taps allow minor voltage adjustments to compensate for input fluctuations or long feeder runs, helping maintain consistent secondary voltage to sensitive equipment. Practically, this reduces nuisance tripping, protects components from over/under-voltage stress, and supports stable motor performance and sensor accuracy in production lines.
The V48M28F15ESNV is UL Listed, confirming compliance with safety standards for electrical equipment in control panels and industrial environments. It includes a electrostatically shielded construction for EMI control, a totally enclosed non-ventilated enclosure for harsh environments, and a 115°C rise rating, all contributing to predictable, safe operation over the product lifetime.
Maintenance is typically minimal due to the dry-type, enclosed design and aluminum windings, reducing stray moisture concerns and maintenance intervals. ROI is enhanced by improved uptime, reduced cooling requirements, and easier installation in dense panels, with a one-year to eighteen-month warranty window aligning with standard commissioning cycles and long-term reliability.
