Keysight (Agilent) N8924A Autoranging System DC Power Supply, 750 V, 20 A

The Keysight N8924A is a 5 kW autoranging DC power supply rated for 750 VDC output at 20 ADC maximum. Unlike conventional supplies with fixed voltage/current ratings, autoranging delivers full 5000 W across any voltage and current combination within its envelope - at 750 V, available current is 6.7 A; at lower voltages, current scales to maintain constant power. This flexibility eliminates the need for multiple units, reducing rack space and cost in ATE and production test environments.
