Keysight (Agilent) N6972A Advanced Power System – DC Power Supply, 40 V, 50 A, 2000 W

The Keysight N6972A Advanced Power System is a single-output DC power supply delivering 2000 W across 0–40 V DC and 0–50 A DC in a compact 2U rack-mount form factor. Built on Keysight's VersaPower architecture, it combines high-speed voltage and current programming with precision measurement capabilities to accelerate ATE test cycles and reduce development overhead. The unit achieves test speeds up to 100× faster than standard system supplies through 3 ms voltage programming, 100 µs transient response, and integrated power analysis functions.
