The 15 kVA, single-phase transformer delivers reliable stepping from 480 V to 120/240 V for industrial control panels, providing stable voltages that reduce equipment wear and trip risks, which translates to shorter downtime and improved line efficiency. Copper windings offer high conductivity and durability, boosting long-term performance and reducing energy losses in demanding environments, ideal for machine controls and panel boards in manufacturing settings. A NEMA 3R enclosure enables indoor-outdoor installation, protecting both transformer windings and terminations from dust, moisture, and incidental wash downs, which lowers maintenance costs and extends service life in outdoor plant areas. Tap settings—two taps at +2.5% FCAN and two at -2.5% FCBN—allow precise voltage adjustment to accommodate slight utility fluctuations, ensuring equipment operates within tolerance and minimizing performance anomalies. The low noise level of 42 dB supports dense equipment layouts near offices or loading docks, improving operator comfort and compliance with noise regulations. UL Listed certification confirms adherence to safety standards, simplifying procurement, audits, and warranty validation while reducing risk for sensitive automation systems. This transformer’s compact footprint and 16A wiring connection simplify installation, enabling faster commissioning and scalable expansion within existing power distribution schemes.
