FAQs
Plan for proper indoor mounting clearance, adequate ventilation, and supported floor space. The unit measures 16.5 in L, 23 in W, and 30 in H with a weight of 358 lb, so ensure a sturdy, level foundation and appropriate access for maintenance and connections (203X wiring) while complying with local codes and the NEMA TP-1 guidelines.
Primary voltage is 480 V, secondary voltage is 208 Y/120 V, rated at 15 kVA, three-phase, 60 Hz. Phase shift is -30°, and voltage taps include 2 at +2.5% and 4 at -2.5% for voltage regulation, supporting stable operation under varying load and line conditions.
Yes. The transformer’s harmonic mitigating design, copper windings, electrostatic shielding, and -30° phase shift help minimize harmonic interactions with nonlinear loads typical of data centers and modern manufacturing, improving power quality and reducing trip incidences and equipment stress.
This unit is UL Listed, complies with NEMA TP-1, and is NEMA TP-1 efficient. These certifications ensure safety, energy efficiency, and regulatory alignment for compliant installation and long-term performance in industrial or commercial facilities.
The dry-type design, copper windings, and shielded construction reduce maintenance needs and heat losses, contributing to longer equipment life and lower operating costs. The 1-year warranty (or 18 months from shipment) provides initial risk coverage, supporting a favorable total cost of ownership in regulated, power-sensitive environments.
