The Chroma 63800R Series Regenerative AC Electronic Load offers a cutting-edge solution for advanced AC load testing. Designed with a regenerative architecture, the 63800R returns up to 90% of the absorbed energy back to the grid, significantly reducing energy consumption and heat generation compared to traditional loads.
This series supports versatile AC, DC, and AC+DC loading, making it ideal for testing uninterruptible power supplies (UPS), inverters, AC sources, and other grid-connected devices. It offers high-performance loading modes including constant current, constant power, constant resistance, and constant impedance. Harmonic simulation up to the 50th order allows users to simulate non-linear load behavior, ensuring comprehensive validation.
The Chroma 63800R also features transient simulation and flicker testing capabilities, critical for assessing power quality and compliance with standards. Its master/slave design allows multiple units to be paralleled for higher power needs without compromising control precision. With integrated measurement functions, a user-friendly interface, and advanced programming features, the 63800R ensures accurate, efficient, and flexible load testing for a wide range of applications.
