The Xantrex XFR 300-4 is a 1200 W programmable DC power supply engineered for research, product development, and production testing. It delivers 0–300 Vdc at 0–4 Adc with zero-voltage soft switching technology that maximizes efficiency, minimizes noise, and enhances reliability. The unit operates across 0 to 50°C at full rated power with no derating and fits standard 19-inch rack mounts in a 1U (1.75-inch) chassis, enabling stackable deployment without inter-unit ventilation gaps.
