Overview

Hammond Power Solutions SK3A0045PK9K is a 600V Class DOE2016 and NRCan 2019 compliant energy-efficient K-Factor 9 transformer designed for environments with harmonic distortion from non-linear loads. This three-phase, copper-wound transformer delivers 45 kVA with a primary voltage of 480Y/277V and secondary voltage of 600D PV. The shielded design provides superior noise reduction and electromagnetic interference (EMI) suppression, making it ideal for sensitive electronic equipment in commercial, industrial, and data center applications. Key specifications include a K-Factor 9 rating to handle harmonic currents up to the 9th order, protecting downstream equipment from overheating and premature failure. Compliance with DOE2016 and NRCan 2019 energy efficiency standards ensures reduced energy consumption and lower operational costs. The transformer features a compact footprint with dimensions of 25.8" (655 mm) width, 23.8" (605 mm) depth, and 28.8" (732 mm) height, weighing 420 lbs (191 kg). It is designed for floor mounting with optional wall/ceiling mounting via the DW3 kit. The SK3A0045PK9K includes front-accessible high and low voltage terminals with lugs for easy cable installation, suitable for both copper and aluminum conductors. It meets NEMA ST-20 sound level standards and features a heavy-duty ventilated Type 3R enclosure with ANSI 61 Grey finish. The transformer is UL Listed (File: E112313) and CSA Certified (File: LR3902), with an insulation system rated at 220°C (150°C rise) and a typical impedance of 3% to 6.5%. Factory-installed grounding lugs and pre-installed lugs simplify installation, while vibration isolation pads and drip shields enhance durability in demanding environments.
