Agilent/Keysight AC6801B

The Keysight AC6801B is a 500 VA AC power source engineered for testing and evaluation of electronic devices across diverse power conditions. It delivers stable, programmable output across dual voltage and current ranges, with maximum peak currents reaching 15 A at 155 Vrms and 7.5 A at 310 Vrms. The instrument operates from 40 Hz to 500 Hz and includes DC output capability up to 400 W, making it suitable for both AC and DC testing scenarios.

Built-in measurement functions capture voltage, current, and power in AC, DC, and AC+DC modes, with inrush current characterization via phase-angle control. Remote sensing and programmable output enable precise power conditioning for real-world simulation including non-ideal networks, voltage fluctuation, and transient spike injection.
