The new high-power ATE portfolio packs more power into less rack space, automates long and complex validation runs and returns energy to the grid rather than wasting it as heat, helping engineers test tomorrow’s high-power designs faster, more securely and more sustainably.
Power validation is getting harder. Electronic designs draw more power, demand more test channels and face stricter conformance, security and sustainability requirements, all while lab and production floor space stays at a premium. Development teams need automated test equipment that delivers more power in a smaller footprint, runs complex scenarios without manual programming, and keeps energy and cooling costs under control.
Available from Milexia UK, Keysight’s new high-power ATE range answers that challenge with a family of compact, regenerative DC power supplies and electronic loads spanning 1.2 kW to 12 kW. With up to 6 kW in a 1U chassis and 12 kW in 2U and 2 – 3x more channels in the same footprint as previous systems, the portfolio brings density, automation and sustainability together in a single rack-ready solution.
Explore the High-Power ATE Range
EL4900 Series Regenerative DC Electronic Loads
1.2 kW to 12 kW, 10 V to 1500 V, up to 720 A
Precision loading for power device testing, from validation to transient analysis. The regenerative design returns up to 95% of absorbed energy to the grid, cutting energy and cooling costs without disrupting grid performance, in compact 1U and 2U formats.
RP5900 Series Regenerative DC Power Supplies
1.7 kW to 12 kW, bidirectional source and sink
A two-quadrant supply with an integrated regenerative electronic load in one unit, switching seamlessly between sourcing and sinking current. Autoranging output covers 10 V to 1500 V and up to 1020 A, with up to 95% energy regeneration.
DP5800 Series DC Power Supplies
10.2 kW to 12 kW in 2U, up to 1020 A
High-density, programmable DC power with autoranging output from 10 V to 1500 V, built-in voltage and current measurements and a built-in arbitrary waveform generator, the flexibility needed for demanding R&D, design validation and production test.
High-Power ATE Key Benefits
More power in less space: Up to 6 kW in 1U and 12 kW in 2U, delivering 2–3x more channels in the same footprint as previous systems, so you can scale test capacity without scaling your rack.
- Automation at the core: Keysight’s PathWave Advanced Power Suite automates long-duration cycling, state-of-charge battery emulation and transient replication, with parallel operation of up to 16 units for higher combined power
- Secure, standards-ready workflows: A removable SD card supports safe operation between classified and open labs, backed by software developed to the NIST SP 800-171 Secure Software Development Framework
- Sustainable by design: Regenerative operation returns up to 95% of absorbed energy to the grid rather than dissipating it as heat, reducing both energy and cooling costs
"Engineers today face unprecedented challenges as power devices become larger, more complex, and more critical to innovation across industries. With this new portfolio of high-power ATE solutions, we are giving engineers the density, automation and sustainability they need to accelerate validation, reduce risks and confidently bring next-generation technologies to market."
