AS0 Series Low-current Sensors are pecialized current operated switches that ombine an ultra-sensitive current transformerd signal conditioning electronics nto a single package for sensing AC current fom 3-350mA. Useful for signal or amp status monitoring, detecting minute fault currents or fan proving, the AS0 eries features solid-state outputs and jumper-selectable ranges, which make it versatile choice for low-current status indication applications.
