The Xantrex XFR40-70 Low Profile DC Power Supply 40V, 70A provides 2.8 kilowatts of power for research, product development, and production test applications such as magnet control, ATE, process control, electroplating and burn-in. The XFR40-70 is ideal for applications where high power and a wide adjustment of output voltage or current is required. The XFR40-70 is designed for excellent thermal management so each unit can be conveniently stacked in rack mounts without leaving ventilation space between each unit. The XFR40-70 Series features zero voltage “soft switching” which virtually eliminates switching transients, resulting in lower noise performance that is closer to linear levels. Soft switching also increases efficiency, decreases heat generation, and reduces stress on the switching transistors – resulting in higher reliability.
