From the leader in programmable power products, Sorensen introduces the SL series electronic loads which offer the best value with the most flexible platform. A wide range of loads are available from 75-1800W with both DC and AC input in benchtop, modular and standalone form factors.
The SLM chassis are available in a convenient single-bay configuration (see image on the right) for benchtop/desktop applications and a four-bay configuration (see image on the left) for multichannel and ATE requirements. Either chassis is compatible with SLM- and SLD- loads. Each chassis contains non-volatile memory capable of storing up to 150 module setups and nine 16-step sequences for automated, standalone testing. Or for more complex test sequences, the chassis come with GPIB (optional on SLM-1) and RS-232 as standard interfaces.
