The G5.RLD series are unidirectional regenerative sinks which can operate in CV, CC, CP, CR, and Ri-Sim control modes. It is universally applicable and therefore suitable as a sink for all industrial and scientific applications in laboratories as well as on test benches and production lines. The modular and finely graded G5.RLD series is characterized by highly dynamic response times, adjustable filter time constants, and a wide current-voltage range with an auto-ranging factor 3. Optional software, programming and communication interfaces as well as safety functions enable the G5.RLD loads to be optimally adapted to special customer application requirements.
