Keysight (Agilent) N6733A DC Power Supply, 20 V, 2.5 A, 50 W, Programmable

The Keysight N6733A is a single-channel programmable DC power module engineered for integration into N6700 or N6705 series modular power systems. This 1-slot module delivers 20 V at 2.5 A maximum output, with 50 W total power capability. It combines voltage programming accuracy of ±0.1% + 20 mV with current readback accuracy of ±0.15% + 20 mA, making it suitable for device testing, system characterization, and ATE resource allocation.
