'AS0' Low-Current Sensors from NK Technologies are specialized current operated switches which combine an ultra-sensitive current transformer and signal conditioning electronics into a single package for sensing AC current from 3-350mA. Useful for signal or lamp status monitoring, detecting minute fault currents or fan proving, the ASO features solid-state outputs and jumperselectable ranges, which make it a versatile choice for low-current status indicating applications.
