The Chroma 63700 Series Regenerative DC Electronic Load is a next-generation solution for energy-efficient and high-precision testing of power conversion devices. Designed to not only absorb but regenerate energy back into the grid, this series offers exceptional savings on energy costs while maintaining high testing performance.
Covering a wide voltage range (up to 1200V) and scalable power up to 108kW, the 63700 Series suits a variety of demanding applications such as electric vehicle (EV) powertrains, renewable energy systems, power supplies, and battery modules. Its regeneration efficiency reaches up to 93%, minimizing heat dissipation and reducing cooling requirements.
The load can operate in multiple modes—constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP)—allowing it to simulate real-world load conditions with remarkable accuracy. It features ultra-fast dynamic responses and adjustable slew rates critical for transient testing.
Additionally, the Chroma 63700 supports programmable load sequences, enabling engineers to simulate complex load profiles. Standard interfaces like LAN, USB, and CAN (plus optional GPIB) ensure easy integration into automated test systems. Built-in protections safeguard both the equipment and the device under test (DUT).
Highly efficient, flexible, and easy to use, the Chroma 63700 Series is an essential tool for modern power electronics testing where energy conservation and performance are equally critical.
