Keysight N5751A/903 DC Power Supply

Overview

The Keysight N5751A/903 is a 750W DC system power supply offering 0–300V, 0–2.5A output in a compact 1U-high, 19-inch package. It features universal AC input (100–200 VAC) with 0.99 power factor correction and comprehensive protection against overvoltage, overcurrent, and excessive temperature. The front-to-back airflow design eliminates the need for additional rack space above or below the unit, making it ideal for dense automated test equipment (ATE) installations.
