To address these challenges, Keysight has launched a new family of high-density power solutions, designed to deliver high power capacities in a small footprint, with regenerative capabilities, advanced automation, and integrated safety.
Architecture and Design Approach
The solutions are organized into three main series:
1. DP5700 Series High-Density DC Power Supplies:
This series includes compact DC power supplies delivering from 1.5 kW to 5 kW per unit. They are available in half-rack and 1U form factors, enabling efficient integration into space-constrained ATE (Automated Test Equipment) systems.
Key technical features:
Up to 600 V and 500 A in full-size models.
High-density design maximizes power in a standard rack.
Removable SD memory, ideal for test environments with data classification and safety requirements.
Standard interfaces such as LAN, USB, and GPIB, and LXI Class C compliance for integration into automated systems.
Ability to parallelize and scale multiple units to achieve higher power or voltage configurations.
These units are designed to deliver clean, stable power, with integrated voltage and current measurements that facilitate the characterization and validation of power devices.
2. RP5900 Series Regenerative Power Supplies
. The RP5900 series consists of bidirectional regenerative power supplies. This means they can both supply power to the device under test and absorb and return power to the grid with efficiencies of up to approximately 95% during extended load/cycle operations.
Key features:
Power range: 2 kW to 12 kW per unit.
Maximum voltage up to 800 V, current up to 240 A.
Available in 1U and 2U sizes, facilitating high power density.
The ability to recover electrical energy during extended test flows—such as battery cycling or efficiency testing—reduces heat dissipation and operating costs for large test facilities.
3. EL4900 Series Regenerative Electronic Loads
Complementing regenerative power supplies, the EL4900 series offers regenerative electronic loads that can also absorb power and return it to the overall power system. This is especially useful in battery discharge testing and dynamic load simulation.
Key specifications:
Similar power rating to the RP5900 series: 2 kW–12 kW.
Supports voltages up to 800 V and currents up to 240 A.
Compact and scalable design for laboratories and ATE systems.
Automation and Intelligent Software
A key component of Keysight's technical approach is its software suite for power test automation. Automation enables:
Running complex cycles without extensive manual programming.
Emulating real-world battery discharge curves and transient conditions.
Ensuring complete and repeatable test coverage.
Furthermore, data security is built into the design: removable memory and software solutions comply with standards such as NIST SP800-171 SSDF, which is critical in defense and enterprise-class environments.
Scalability and Density:
A fundamental component of technical design is power density per rack unit. The series offers
up to 6 kW in 1U or 12 kW in 2U, with scalable capacities through parallel connection.
This facilitates having more test channels in the same physical space, reducing the overall footprint of the laboratory.
This is especially relevant in applications where multiple high-performance units must operate simultaneously for testing complete systems, such as in data centers, energy storage, or aerospace applications.
Key Technical Applications
These solutions are designed to address common challenges in advanced industries such as:
Aerospace and Defense: testing power systems on satellites or spacecraft under real-world dynamic conditions.
Energy Storage Systems: repeated charging and discharging of high-capacity batteries.
Data Centers and Power Electronics: validation of power supply units (PSUs) and power systems without active infrastructure.
In conclusion,
Keysight's High Power Density solutions represent a significant advancement in power test engineering, offering:
efficient integration into high-density racks;
regenerative capabilities that reduce energy consumption;
advanced automation that accelerates validation with greater accuracy;
and scalability for demanding applications across multiple industries.
This technical approach combines robust hardware with intelligent software and enterprise-grade security options, positioning Keysight as a leading provider of next-generation power test equipment.
