Keysight (Agilent) 6652A System Power Supply, 500 Watt, 20V, 25A

The Keysight (Agilent) 6652A is a 500-watt, single-output, linear-regulated DC power supply engineered for automated test systems and demanding benchtop applications. It delivers 0 to 20 V at up to 25 A (at 40°C), with current derating to 22.5 A at 50°C and 21.3 A at 55°C. Fast programming times for voltage and current maximize test throughput, while precision control and monitoring are achieved through SCPI commands via GPIB or analog remote programming.
