Agilent / Keysight N3303A 250 Watt Electronic Load Module

The N3303A is a 250 W electronic load module engineered for integration into Agilent/Keysight N3300A or N3301A mainframes. It delivers fast, accurate performance across DC power supply, DC-to-DC converter, and battery testing applications in high-volume ATE environments. The module accepts 0–240 V at 0–10 A with full stability down to zero volts and minimum operating voltage of 1.2 V at full scale current.
