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.

Maximum power 1000 W to 30 kW
Maximum voltage per output 9 V to 2000 V
Maximum current per output 16.7 A to 800 A
Input phase voltage 3 Phase 400/480 VAC, 3 Phase 200/208 VAC, Single Phase 100/240 VAC
Noise and ripple 9 mVpp to 3000 mVpp
Regenerative power Measurement accuracy
3.7 mV to 750 mV Output response time

Highlights

Output ratings: 1000 V, ±90 A, 30 kW.

  • Operate in two-quadrant mode as a power source and regenerative electronic load.
  • Maximize throughput with fast output speed and sub-millisecond command-processing time.
  • Create up to 600 kW power or loading through easy parallel connection.
  • Reduce the cost for cooling and electricity with an eco-friendly, regenerative design.
  • Save valuable rack space with a compact 5U-high size.
  • The system is part of Keysight’s HEV/EV Power Converter Test Solution.
  • The Keysight RP7982A regenerative power system is a single output, bidirectional, regenerative DC power supply with highly integrated safety features that protect both your people and your device under test (DUT). The regenerative capability enables the energy normally consumed to return to the grid cleanly, reducing energy consumption and cooling costs.
  • In addition, by combining the seamless source and load functionality into a compact 5U-high package, you save energy, floor space, and integration time. The RP7982A delivers a fast, accurate, and integrated regenerative power system.
  • The RP7982A is part of Keysight’s HEV/EV Power Converter Test Solutions that gives you the confidence needed to deploy high-voltage, high-power solutions to meet the fast-paced, high-growth demands of the HEV/EV market.

  • Reduce costs for cooling and electricity with an eco-friendly regenerative design
  • The regenerative capability of the RP7900 enables energy to be put back onto the grid cleanly, saving on costs associated with energy consumption and cooling while not interfering with the grid. When the RP7900 is sinking current either from rapid down-programming of the output or from discharging an energy source like a battery, it automatically returns the excess power to the grid.
  • The regenerative operation is automatic, so it requires no programming. To safeguard your DUT, the RP7900 provides “anti-islanding” that senses the grid is live before regenerating power back to it. With greater than 80% efficiency, the RP7900 helps you reduce energy consumption by using less electricity when sourcing or sinking and less heat dissipation, which lowers the air conditioning needed when sinking.
  • Additionally, the RP7900 provides clean regenerative operation by keeping the total harmonic distortion to a minimum of 2% (typical) at full load to minimize interference with other electronics.
  • Continuously source and sink current
  • The RP7900 can continuously sink up to 100% of its rated current for an indefinite time. The two-quadrant, bidirectional sourcing and sinking capability of the DC power supply allows for seamless, uninterrupted transitions between sourcing and sinking current without changing the power supply’s output characteristics or introducing disruptive behavior.
  • Accelerate test throughput with industry-leading specifications
  • Shaving seconds or even milliseconds off of test time can lead to significant savings for high-volume manufacturers, as throughput gains are a never-ending quest for test system designers. The RP7900 is a valuable tool for increasing throughput. It provides fast output speed, sub-millisecond command processing time (≤ 1 ms), and an output list capability that can help you achieve significant throughput gains in your testing.
