The PSI 10000 3U series are high-performance programmable DC power supplies in a 19-inch 3U rack enclosure, delivering 5 kW to 15 kW per unit with output voltages 0–60 V up to 0–2000 V and currents 0–20 A up to 0–510 A. A flexible autoranging output stage provides higher voltage at lower current, or higher current at lower voltage, so one unit covers a wide range of applications. The PSI adds an integrated function generator with predefined curves, automotive test routines (LV123, LV124, LV148) and a photovoltaics test mode (EN 50530) to the basic PS 10000 feature set, making it suited to automotive, renewable-energy, battery and industrial R&D and production testing. The 3U models listed here are the standard 208 V / 380–480 V AC versions; dedicated US208V models with their own article numbers are available on request.
