Keysight Expands High-Power Test Portfolio With New 12 kW DC Power Supplies

Keysight Technologies has expanded its high-power automated test equipment (ATE) portfolio to provide engineers with more voltage and power options for different testing applications. The expanded range combines compact power hardware, automated software and energy recovery technology. It includes new voltage options for regenerative power supplies and electronic loads, along with a new series of DC power supplies offering up to 12 kW of output power.

Engineers working in power conversion, aerospace and energy applications need test equipment that can handle different voltage and current requirements while using limited rack space, reducing programming effort and controlling energy consumption. Keysight addresses these needs with compact hardware, automated testing and regenerative technology that recovers energy during tests involving power consumption.

The latest additions extend coverage from high-current, low-voltage applications to systems operating at up to 1500 volts (V). This enables engineers to configure power test systems for applications such as power-stage characterization, battery testing, charging systems, power conversion, and aerospace equipment.

Key benefits include:

Broader application coverage: New 10 V options provide up to 1020 amperes (A) of source current for power-stage characterization, DC bias, and burn-in testing. Additional 32 V, 300 V, and 1500 V options support nominal 24 V and 28 V systems, nominal 270 VDC aerospace equipment, up to 1500 V battery modules, power converters, and charging applications.
Increased rack density: Regenerative power supplies and electronic loads provide up to 6 kW in one rack unit (1U) or 12 kW in two rack units (2U). The new DC power supply family provides up to 12 kW in 2U, while other portfolio options provide up to 7.5 kW in 1U. This enables engineers to benefit from two to three times as many channels in the same footprint as previous systems.
Faster, more efficient workflows: PathWave Advanced Power Control and Analysis software and PathWave Advanced Battery Test and Emulation software enable engineers to configure tests and analyse results with less custom programming.

Carol Leh, Vice President, Electronic Industrial Solutions Group Center of Excellence at Keysight, said: “Power test requirements vary significantly across applications, but engineering teams share the need to increase capacity, conserve rack space, and simplify automation. These additions give customers more flexibility to configure efficient, repeatable test systems that can scale as their requirements change.”

The expanded portfolio is built on Keysight’s Power Without Compromise solutions, which were introduced in November 2025. The portfolio also includes 5 kW and 7.5 kW power supplies introduced in the first half of 2026. The 7.5 kW offering supports ratings up to 1500 V and automatic paralleling of up to 12 units for systems delivering up to 90 kW.
