FAQs
For installation, verify primary 480 V supply and 208Y/120 V secondary connections, ensure adequate ventilation for the ventilated transformer, and confirm WS34 weathershield suitability if outdoor use is anticipated. Plan for frame 918A mounting, provide proper clearance for heat dissipation, and reference the catalog notes for sound levels (52 dB) to align with plant noise criteria.
Key specs include a 225 kVA rating, 60 Hz frequency, three-phase configuration, primary voltage 480 V, secondary 208Y/120 V, and taps of 2 at +2.5% and 4 at -2.5%. The transformer uses copper windings, has an electrostatic shield, a frame 918A, with a 150°C rise rating and a low-noise profile of 52 dB.
Yes, the unit is equipped with WS34 weathershield compatibility and a rugged frame (918A) that supports outdoor installations in appropriate environments. Ensure proper enclosure protection, follow clearance for ventilation, and confirm ambient temperature and humidity conditions align with the 150°C rise rating and UL Listed safety certification.
The K-Factor nonlinear design helps mitigate harmonic currents and improves overall power quality, reducing stress on upstream and downstream equipment. This translates to longer component life, lower maintenance costs, and better compliance with harmonic standards in facilities with sensitive drives and controllers.
