The Sorensen SLM60-30-150 is a modular DC electronic load module engineered for high-precision power supply testing and validation. Operating at up to 60 V and 30 A with a maximum power dissipation of 150 W, this unit delivers five distinct operating modes—Constant Current, Constant Resistance, Constant Voltage, Constant Power, and Short Simulation—making it adaptable to complex test scenarios. The module integrates into SLM series mainframes (single-bay benchtop or four-bay rackmount configurations) where up to four modules can be stacked for expanded test capacity.
