The Sorensen SLM1 is a modular electronic load chassis that houses SLM and SLD series load modules, providing a configurable platform for power analysis, electronics testing, and product development. Single-bay benchtop and four-bay multichannel configurations accommodate diverse laboratory and ATE requirements. The chassis stores up to 150 module setups in non-volatile memory and executes nine 16-step automated test sequences for standalone operation.
