The SC6XX-XX series of split-core current sensors monitor line current for electrical loads such as pumps, conveyors, machine tools or fans and provide an output of 4-20 mA, 0-5 Vdc or 0-10 Vdc (Model specific) to represent the load current.

The SC650 & SC651 series require no external power supply as they are totally powered by induction from the AC line being monitored. The SC652 & SC675 series are loop-powered and require an external 15-30 Vdc power supply.
