The HP/Agilent 6031A is a system autoranging DC power supply delivering 0–20 V and 0–120 A with 1064 W maximum power output. Autoranging capability eliminates manual reconfiguration, allowing the supply to transition across three operating points—20 V/50 A, 14 V/76 A, and 7 V/120 A—while maintaining maximum available power. This eliminates the need for multiple supply units and reduces system footprint.
