Complete capability power supplies with regenerative options
Keysight Pro ATE power supplies come in two classes. The NS1-class includes the N7900 Series, and the NS4-class includes the RP7900 Series. They are high-performance, autoranging DC power supplies engineered for automated test environments that demand speed, accuracy, and flexibility. Offering up to 30 kW in a compact 5U form factor, our Pro models deliver fast output response times, wide voltage and current ranges, and precise control to support a broad range of dynamic test applications. Our Pro ATE supplies are ideal for testing automotive components, aerospace systems, and industrial electronics. Choose one of our popular configurations or configure one specific to your application.
Ultra-high power
Test high-power systems up to 30 kW — such as renewable energy systems, electric vehicle powertrains, data centers, and industrial motor drives — using a single, integrated unit.
Real-time control
Hardware-based control enables immediate adjustments of voltage and current based on external sensors or triggers, supporting a closed-loop testing environment.
High-speed digitization
Provides up to 1.6 MSa/s sampling for voltage and current, enabling scope-grade waveform capture and analysis directly from the power supply.
Built-in AWG
Simulate dynamic real-world power conditions by directly outputting complex, time-varying voltage and current profiles from the power supply.

Frequently asked questions
Yes, most ATE system power supplies are designed for fast voltage and current response times, making them suitable for applications that require dynamic power adjustments, such as testing high-speed digital circuits or simulating real-world load conditions.
The regenerative technology allows us to not only source power but also sink power, returning energy to the grid. This reduces wasted energy and lowers cooling requirements, making it highly efficient for testing energy storage systems, battery emulation, and bidirectional power devices.
Regenerative power supplies reduce electricity consumption by recycling energy back to the grid. This results in lower operational costs, less heat dissipation, and a smaller environmental footprint compared to conventional power supplies.
Yes, some higher-end ATE system power supplies’ bidirectional design allows it to seamlessly transition between sourcing and sinking power, making it ideal for testing battery charging and discharging cycles as well as evaluating energy storage systems' performance.
