The Xantrex XFR100-28 is a 2800 W programmable DC power supply engineered for precision output regulation across research, development, and production testing environments. Built on zero-voltage soft-switching topology, the unit minimizes switching transients to achieve 81% efficiency, reduced thermal output, and extended operational life. The supply accepts single-phase 190–264 VAC input at 47–63 Hz and delivers 0–100 Vdc at 0–28 A with exceptional load and line regulation.
