NK Technologies ASM Series Load Monitoring Self-Calibrating AC Current Operated Switches, Self-Powered, SmartLED, 1.5 - 150A Setpoint Range for Fixed Core Units, 2.5 - 150A Setpoint Range for Split Core Units

The 'ASM' Series Load Monitoring Switches from NK Technologies are designed for overload, underload or operating window applications.  Upon sensing an average operating current, the ASM selflearns and establishes a limit-alarm trip point based on +/- 15% of the average expected current draw. The ASM offers a choice of solid state outputs and is available in solid or split-core enclosure styles.
