FAQs
Installation requires proper floor and enclosure space for a heavy 1635 lb unit with dimensions of 24.67 in by 31.44 in by 56.17 in. Ensure adequate ventilation, access for connections, and mounting on vibration-damped supports. Use the WS34 weather shield for outdoor applications and follow UL Listed installation guidance to maintain safety and warranty.
The transformer provides 150 kVA, three-phase, at 60 Hz, with a 480 V primary and 208Y/120 V secondary. It uses copper windings, features an electrostatic shield, and offers taps at 2 at +2.5% FCAN and 4 at -2.5% FCBN. Temperature rise is rated at 150 °C, with a frame designation of 917.
Yes. Its K-Factor nonlinear design mitigates harmonic impact, supporting cleaner power delivery to sensitive loads. The 150 kVA rating and robust shielding help maintain voltage stability and EMI control, while the copper windings and weather shield enable reliable operation in both indoor and outdoor automation environments.
The N48M28T49CU is UL Listed, ensuring compliance with safety and performance standards for electrical equipment. For specific project requirements, verify compatibility with local codes and any additional certifications your facility may mandate.
Expect lower maintenance due to robust copper windings and durable shielding, with uptime supported by the electrostatic shield and WS34 weather protection. Heavyweight and footprint considerations impact installation cost and space planning, but the 150 kVA capacity and reliable cooling can yield long-term energy efficiency and reduced downtime in industrial power paths.
