ASM Series Self Calibrating AC Current Sensor

The patented designed ASM Series AC Current Sensor is more accurate and easier to use than previous models. This Self Calibrating Smart-Switch uses the actual load current to set the trip point. It takes just a couple of seconds of steady running conditions before the sensor locks onto the normal current level. The ASM Series AC Current Sensor is designed for overload, underload or operating window applications. Upon sensing an average operating current, the ASM self-learns and establishes a limit-alarm trip point based on 85–125% of normal current (overload/underload model only). Available in a solid- or split-core case.
