Overview

The Hammond Power SK3A0045PB3K is a 45 kVA, three-phase, energy-efficient K-factor transformer engineered to mitigate harmonic distortion in non-linear load applications. This unit is compliant with DOE 2016 and NRCan 2019 energy standards, delivering reduced energy consumption and operational cost savings. With a K-factor rating of 13, it safely handles harmonic currents generated by equipment such as variable frequency drives (VFDs), LED lighting systems, and switching power supplies, preventing overheating and extending equipment lifespan. Primary voltage is rated at 600D PV, while the secondary voltage is 208Y/120V, making it ideal for industrial and commercial power distribution systems requiring stable, high-quality power. The transformer features copper windings for superior conductivity, thermal performance, and durability, ensuring long-term reliability and efficiency. Its shielded design minimizes electromagnetic interference (EMI), protecting sensitive downstream equipment from noise and distortion. Constructed with a three-coil, single 3-leg core, this ventilated, convection air-cooled transformer meets UL, CSA, and NEMA standards. It is designed for non-linear load applications and de-rated per ANSI/IEEE C57.110 for safe operation under harmonic conditions. The unit is suitable for a wide range of industrial environments, including manufacturing facilities, data centers, and commercial buildings where power quality and efficiency are critical. Key applications include powering VFDs, UPS systems, medical imaging equipment, and other sensitive electronic loads. The SK3A0045PB3K is built for demanding environments where consistent power quality and energy efficiency are non-negotiable.
