Selling Policy 25-000 - Distribution and Control Products and Services
Harmonic mitigating design reduces harmonic currents and stabilizes the voltage profile across critical loads. This translates to improved motor and drive life, fewer nuisance trips, and lower maintenance costs on production lines and data centers. In practice, clean power supports precision motion control and better protection for sensitive electronics in industrial environments. Three-phase 480 V primary to 208Y/120 V secondary delivers compatible voltage levels across plant feeders. This standardization reduces panelboard complexity and minimizes auxiliary components, cutting installation time and labor costs. It’s ideal for new installations or upgrades in manufacturing floors, data centers, and process lines. Copper windings provide high conductivity and robust thermal performance within the EE frame 919X. This results in better overload tolerance and longer service life in continuous operation scenarios, suitable for heavy loads in facilities with dense electrical cabinets and heat-generating equipment. Dry-type distribution transformer construction offers safer indoor installation and simpler maintenance in controlled environments. The 150°C rise insulation supports reliable operation under ambient heat, while 60 Hz compatibility ensures standard utility supply integration. Tap settings at +2.5% and -2.5% enable precise voltage regulation for sensitive loads. This reduces equipment stress, improves control accuracy, and lowers energy waste in fluctuating supply scenarios. UL Listed and NEMA TP-1 compliant, with electrostatically shielded construction and Weathershield WS35, this transformer is built for industrial reliability and long service life. This combination simplifies procurement and design acceptance by meeting standards and delivering predictable performance in challenging environments.
