The KEYSIGHT N6900 Series Advanced Power System (APS) DC power supplies are designed for high-performance ATE applications where speed, flexibility, and measurement precision are essential. Thanks to the VersaPower architecture, the N6900 Series delivers industry-leading speed, two-quadrant operation, and advanced measurement capabilities in a compact footprint. The series offers 1 kW (1U) and 2 kW (2U) models, all with built-in paralleling up to 10 kW and a wide range of voltage/current combinations.
- 1 kW models (1U) and 2 kW models (2U), all full-rack width
- Voltage options from 9 V to 160 V, current up to 200 A
- Fast up/down programming speeds (as low as 0.5 ms with option 303)
- Two-quadrant operation: source and sink up to 100% rated current (with N7909A dissipater)
- High measurement accuracy: 18-bit resolution, digital multimeter-like precision
- Integrated measurement digitizers, external logging, and Black Box Recorder (options)
- Advanced protection: overvoltage, overcurrent, overtemperature, watchdog timer
- Smart triggering, sequencing, arbitrary waveforms, and output list capability (options)
- LAN (LXI Core), USB, and GPIB interfaces standard; built-in web server for remote control
- Ideal for battery, power electronics, automotive, aerospace, and industrial ATE systems
