Power Test Systems up to 1,500 V With Higher Rack Density 

Keysight Technologies has expanded its high-power automated test equipment (ATE) portfolio with new voltage options for regenerative power supplies and electronic loads, and a new family of DC power supplies delivering up to 12 kW. The additions target engineers in power conversion, aerospace and energy who build power test systems for batteries, charging systems, power stages and aircraft equipment.

Requirements for Modern Power Test Systems
Engineers in these fields must meet defined voltage and current requirements while managing limited rack space, test programming effort and energy consumption. Keysight addresses these points with compact power hardware, automated and repeatable workflows, and regenerative operating modes for tests in which power is absorbed from the device under test.

Extended Voltage and Current Range
The new options extend the portfolio from high-current, low-voltage applications to systems operating at up to 1,500 V. The 10 V options deliver output currents of up to 1,020 A for power stage characterisation, DC biasing and burn-in testing. Additional 32 V, 300 V and 1,500 V options cover 24 V and 28 V systems, aerospace equipment with a 270 VDC rating, battery modules up to 1,500 V, and power converters and charging applications.

Higher Rack Density
The 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 delivers up to 12 kW in 2U, while other models in the portfolio provide up to 7.5 kW in 1U. According to Keysight, this allows two to three times as many channels in the same footprint as previous systems. The 7.5 kW model, introduced in the first half of 2026, supports ratings up to 1,500 V and automatic paralleling of up to 12 units for systems of up to 90 kW.

Software for Configuration and Analysis
With PathWave Advanced Power Control and Analysis and PathWave Advanced Battery Test and Emulation software, engineers can configure tests and analyse results without spending significant time on custom programming.

Carol Leh, Vice President of the 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 builds on Keysight's Power Without Compromise solutions introduced in November 2025 and also includes 5 kW and 7.5 kW power supplies.

Additional Context
This section details technical specifications and competitive benchmarking not included in the original news release.

A comparable product line for regenerative power testing is the EA-PSB 10000 series of bidirectional DC power supplies from EA Elektro-Automatik, distributed by Tektronix. It is available in a 2U chassis at 1.5 kW or 3 kW with up to 1,500 V and 120 A, in a 3U chassis at 5 kW, 10 kW or 15 kW, and in a 4U chassis at 30 kW, with up to 2,000 V in the 3U and 4U versions and up to 1,000 A in the 4U format. In sink mode, the series feeds absorbed energy back into the grid with an efficiency of more than 96%. In terms of power density, the 30 kW 4U model corresponds to 7.5 kW per rack unit, compared with 6 kW per rack unit for Keysight's regenerative units, while the EA series covers a higher voltage range of up to 2,000 V against up to 1,500 V for the Keysight portfolio.
