AC Current Operated Switches simplify monitoring.

December 6, 2012

Available in panel-mount, solid- or split-core enclosure, ASL Series offers user-selectable linear setpoint adjustment for monitoring current in various applications. Contact actuation point can be set with no load present, and 2 sec delay ignores motor inrush current upon energization. While magnetically isolated output maximizes safety and eliminates insertion losses, solid-state design eliminates periodic maintenance and calibration. No external power source is required for operation. Read More
