This unit
The Ametek Xantrex Sorensen XFR 7.5-140 is a 1050 W rated programmable DC power supply engineered for demanding test, research, and production applications requiring precise voltage and current control. This compact 1U rack-mount unit delivers 0–7.5 V and 0–140 A with exceptional output stability, employing zero voltage soft-switching technology to achieve high efficiency and minimal noise. Automatic CV/CC crossover, adjustable overvoltage protection, and remote sensing with up to 5 V line drop compensation ensure reliable operation across diverse load conditions.
The supply stacks without inter-unit ventilation requirements, maximizing space efficiency in multi-channel test benches.
