The Xantrex XHR40-25 is a 1000 W programmable DC power supply for benchtop and system integration in R&D, test, and industrial environments. This half-rack unit delivers 0–40 VDC at 0–25 ADC with universal AC input (85–250 VAC, 47–63 Hz) and integrated power factor correction, operating reliably from standard 120 VAC, 15 A circuits at approximately 11 A input current. Zero voltage soft-switching technology minimizes switching transients, delivering high efficiency and low output ripple.
