NK Technologies ASO Low AC Current Switch
AS0 Series Low-current Sensors are specialized current operated switches that 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 AS0 Series features solid-state outputs and jumper-selectable ranges, which make it a versatile choice for low-current status indication applications.
Wide Range of Output Options
Dependable, solid state switch N.O. or N.C. contacts rated at 240VAC or 30VDC. Compatible with most automation controllers.
Isolated Inputs and Outputs
Inductive sensing eliminates insertion loads on monitored circuits, effectively isolating it from the unit. Isolated outputs simplify wiring and enhance safety.
Adjustable Setpoints
Setpoints are field adjustable from 3mA to 350mA, speeding installation and allowing for tailored applications.
UL, CUL and CE Approval
Applications
Fan Monitoring
Fan status in heating and drying applications.
Identify lamp outages or other malfunctions through changes in current consumption.
Fractional HP Motors
Ideal for monitoring small motors used in critical applications, for example, fan-proving on a crucial cooling fan.
Fault Current Sensing
Detects extremely low levels of current resulting from fault conditions.
