480 Delta Primary Volts - 208Y/120 Secondary Volts - Non-linear loads generate high levels of harmonic currents. When supplying power to these loads, a special transformer design is necessary. Typical non-linear loads include desktop computers, AC variable speed drives, HID lighting, electronic ballasts, inverters and welders. Of these non-linear loads, the major source of harmonic currents is the switch mode power supply found in desktop computers, data processors and other office equipment. Acme Non-Linear Load Isolation Transformers use special winding techniques to minimize eddy current losses generated by harmonic currents. A double-sized neutral conductor handles the excessive neutral current found in non-linear load applications. They are shielded for cleaner power and carry the Acme exclusive 10-year limited warranty.
