The Agilent/Keysight 85901A is a portable AC power inverter that delivers 200 Watts continuous output for field and mobile test applications. It supplies selectable 115 Vrms or 230 Vrms at 60 Hz ±0.1% (crystal referenced), with rectangular waveform output specified at 135 or 270 peak ±5%. The unit integrates a sealed lead acid battery (12 Vdc, 17 Ah nominal) providing up to 2 hours of operation at 100-watt continuous load, or operates from an external 12 Vdc source for extended runtime. A built-in charger accepts 90 to 250 Vac input (auto-selected) and fully recharges the battery in six hours or less. Complete electrical protection includes over-voltage, short-circuit, and over-load safeguards on the inverter output.
