KEYSIGHT N7900 Series: Dynamic DC Power Supplies for Advanced ATE Testing

Posted by Batter Fly 01/07/2025 0 Comment(s) 1036 Test & Mesure,

The KEYSIGHT N7900 Series Advanced Power System (APS) DC power supplies are designed for automated test and research applications that demand speed, precision, and advanced emulation capabilities. Thanks to their modular architecture and two-quadrant source/sink operation, the N7900 Series delivers ultra-fast programming, high-resolution integrated measurements, and advanced generation and acquisition features. Available in 1 kW (1U) and 2 kW (2U) versions, all models can be paralleled up to 10 kW and cover a wide range of voltages and currents.

1 kW (1U) and 2 kW (2U) models, all full rack width
Voltage options from 9 V to 160 V, current up to 200 A
Ultra-fast up/down programming speed (as low as 0.35 ms)
Two-quadrant operation: source and sink up to 100% of 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
Standard LAN (LXI Core), USB, and GPIB interfaces; built-in web server for remote control
Ideal for battery, power electronics, automotive, aerospace, and industrial ATE systems
