The Xantrex XFR 40-70 programmable DC power supply provides clean, reliable power for research, product development, and production test applications. The supplies are ideal for OEM applications where high power and a wide adjustment of output voltage or current are required in a full 19-inch rack package.

The XFR 40-70 has excellent thermal management allowing for units to be stacked in rack mounts without any ventilation space required between each unit. The supplies offer high reliability with zero voltage, or “soft switching”, which virtually eliminates switching transients for high efficiency, decreased heat generation, and reduced stress on the switching transistors.
