Keysight (Agilent) N6755A 20 V, 50 A, 500 W high-performance autoranging DC power module

The Keysight N6755A is a 500 W high-performance autoranging DC power module engineered for automated test equipment and research applications requiring precision power delivery with minimal noise. Operating from 0 to 20 V and 0 to 50 A, this double-wide module combines exceptional speed and accuracy to optimize test scenarios. Autoranging capability flexibly allocates the 500 W power budget across voltage and current combinations, eliminating the need for fixed-range modules. Programming speeds reach 10 to 50 times faster than conventional supplies, while voltage ripple is held to just 5 mV peak-to-peak and 1 mV RMS across the 20 Hz to 20 MHz band.
