Three series, one mission: maximum efficiency and flexibility

In today’s development and testing environments, the demands on power electronics are constantly increasing: higher power density, efficient energy use, flexible scalability, and seamless automation have become standard. At the same time, space, operating costs, and integration effort remain critical considerations.

With three complementary product series — RP5900, EL4900, and DP5700 — Keysight offers powerful solutions that meet these challenges, combining uncompromising performance with high efficiency.

Here’s an overview of the key features and applications of each series.

 

 

RP5900 Series – Regenerative Power Supplies for Versatile Testing

High-power, high-density regenerative DC power supplies with integrated electronic load

The RP5900 Series combines power supply and electronic load in a compact, bidirectional system. Its regenerative design returns energy to the grid, reducing power consumption, heat, and cooling costs.

With power ratings from 2 kW to 12 kW and compact 1U or 2U form factors, these units are suitable for a wide range of test environments, from labs to production lines.

Key Benefits

  • Complete regenerative load and power system for flexible testing scenarios
  • Voltage options of 80 V, 500 V, and 800 V with currents up to ±240 A
  • Operates in two-quadrant mode as both a power source and regenerative load
  • Space-efficient rack design with parallel stacking of up to 16 units
  • Lower operating costs thanks to energy regeneration
  • Built-in waveform generation accelerates battery testing

Paired with the PathWave Advanced Power Suite, users benefit from fast automated workflows, deep insights, and efficient validation of complex power devices.

 

 

EL4900 Series – Regenerative Electronic Loads for Mid-Range Applications

High-power, high-density regenerative DC electronic loads

The EL4900 Series focuses on regenerative electronic loads for mid-range applications. Returning energy to the grid reduces power consumption and cooling costs, while the compact design saves floor space and simplifies integration.

Key Benefits

  • Regenerative load for versatile testing requirements
  • Voltage options of 80 V, 500 V, and 800 V, with current sinking up to 240 A
  • Wide power range from 2 kW to 12 kW
  • High-density 1U/2U design maximises rack efficiency
  • Stackable parallel connections for up to 16 units
  • Comprehensive interfaces: LAN, USB, CAN, plus optional analog, GPIB, and RS-232

When combined with PathWave software, the EL4900 enables fast automation, detailed insights, and reliable validation of complex systems — without compromising performance or flexibility.

 

 

DP5700 Series – High-Density DC Power Supplies for Compact Environments

Compact, secure, high-density power

For space-constrained labs or production floors, the DP5700 Series provides secure, high-density DC power. With 40 single-output models ranging from 1.5 kW half-rack to 3.4 kW full-rack, all just 1U high, these units deliver stable outputs with integrated voltage and current measurement up to 600 V / 340 A.

Key Benefits

  • Extremely space-efficient 1U design
  • Accurate measurements with built-in sensing
  • Comprehensive protection against overvoltage and overcurrent
  • Flexible input options for single- and three-phase power
  • Easy integration via LAN, USB, and GPIB
  • LXI Class C compliance for standardised control
  • Data security through optional removable SD card

These features make the DP5700 ideal for secure testing environments where space is limited.

 

 

Conclusion: Efficiency, Scalability, and Performance Combined

Whether it’s bidirectional regenerative power supplies, high-performance electronic loads, or compact high-density power units, these three series cover a broad spectrum of modern testing requirements.

They share a focus on:

  • maximum energy efficiency
  • high power density
  • flexible scalability
  • easy integration and automation

For businesses, this translates to not only better testing results but also lower operational costs and more efficient use of existing infrastructure.
