The new product lines such as the DP5700 DC power supply, RP5900 regenerative power supply and EL4900 regenerative load provide a comprehensive solution for high-performance industrial testing requirements, especially in the fields of electric vehicles, energy, automation and power electronics.

The highlight of this product group is the ability to have many specialized features for high-power devices, allowing for testing in a minimal cabinet size while ensuring accuracy, response speed and durability. This is a great benefit over the traditional generation of devices that are bulky and difficult to expand.
DP5700 High Power DC Power Supply: Large Density, Stable Performance
The DP5700 is a compact yet powerful DC power supply for modern ATE systems. It offers a wide voltage range from low to high, output currents up to hundreds of amps, and kilowatts of power in a low rack unit. This design allows users to build multi-channel test systems with limited space requirements while maintaining high load capacity and high stability.
The device supports waveform programming, internal resistance adjustment, and voltage or current rate control. This makes the DP5700 suitable for simulations of real-world conditions in testing power electronics, drives, and switching power supplies. With removable card storage, users can also securely manage test configurations in environments with high security requirements.
The DP5700 is aimed at customers who need accurate power, easy integration and long-term operation. Upgrades in accuracy, control and security help the device achieve higher reliability than mainstream models, while reducing maintenance and operating costs.
RP5900: Bidirectional Regenerative Power Supply for Modern Tests
The RP5900 meets the need for both power and energy absorption thanks to its bidirectional operation. It is available in capacities from 2 to 12 kilowatts with voltage options of 80, 500 and 800 volts, making it suitable for charge-discharge tests, battery simulation, inverter testing, powertrain testing and high-power loads. By returning energy to the grid, the RP5900 reduces long-term operating costs while limiting heat loss to the environment.
The RP5900's power density is unmatched in its class, delivering up to 12 kilowatts in two rack units. This is especially useful when scaling a system to multiple channels or integrating into a test chamber with limited space. Up to eight units can be paralleled to provide a total system power of 96 kilowatts, providing the flexibility to build a system to meet your needs.
The RP5900 is compatible with Keysight's power analysis software, allowing users to view waveforms, calculate performance, and simulate various operating conditions. This is important to shorten product development time and improve test accuracy in the electric vehicle, automation, and energy industries.
EL4900: High power regenerative load for heavy load testing
The EL4900 is a regenerative electronic load series that can absorb and return energy to the grid similar to the RP5900. This product line supports multiple control modes such as voltage, current, power and impedance, allowing flexible simulation of load conditions in power systems, converters and power electronics. The regeneration capability allows the device to operate stably over extended test cycles with low heat loss.
The device is available in 2, 4, 6 and 12 kilowatt versions in a compact design in one or two rack units. This is a great advantage when deployed in systems that require multiple load channels but do not want to increase the size of the test cabinet. The programming and measurement accuracy are optimized to meet the requirements in industrial product testing and new energy equipment.
The EL4900 also supports battery simulation and power analysis, which is suitable for charge-discharge tests and energy storage device research. The ability to combine multiple operating modes helps users create more realistic test scenarios, thereby accurately evaluating the load capacity and durability of the device.
Benefits of implementing in industrial ATE test systems
The DP5700, RP5900 and EL4900 family of devices help users build high-power density ATE systems that are easy to expand and optimize operating costs. Using small-sized but high-power devices reduces the number of racks, reduces cooling costs and creates space for other measurement devices. This is one of the important factors when businesses want to increase testing capacity without changing the entire infrastructure.
The regenerative power capabilities of the RP and EL models help save energy costs during extended testing, especially in R&D and production environments where equipment needs to operate for many hours at a time. Keysight’s integrated software ecosystem supports rapid data management, simulation, and analysis, helping to shorten processing times and improve overall system efficiency.
In addition, advanced features such as waveform programming, internal resistance control, fast response speed and high accuracy make the device suitable for both research and development and production testing. Enterprises can use the same device structure for many types of tests, reducing investment costs and increasing flexibility when changing processes.
