New ASXP-LS Current Switches from NK Technologies Take Complexity Out of Monitoring High-Current Loads

New switches deliver superior reliability, long-term durability and easy installation

SAN JOSE, CA – NK Technologies introduces ASXP-LS Current Switches – a combination current transformer and signal conditioner designed specifically for monitoring large loads. The ASXP-LS Current Switches feature electromechanical relay output, external power source, simple field setpoint adjustment and easy installation. The mechanical relay contact provides a trouble-free, durable alarm or interlock, improving safety and overall system reliability, while the selectable "Fail Safe" operation provides protection for critical loads.

ASXP-LS Current Switches are used to monitor large machines for over- or under-load conditions, detect open discharge lines and sense clogged filters. They can also monitor generators to shed non-critical loads when demand reaches a set level. Key features inlcude:

*Split-Core Housing: Allows sensor to be installed over existing conductors

*Easy Installation: Snap onto DIN rail or attach to back panel through sensor base

Larger Sensing Aperture: Large window (2.3" w x 3.42" h) easily accommodates conductors and multiple wires per phase

*Electromechanical Relay Output: Use with AC or DC control circuits and for no-volt inputs (e.g. timing relay triggers)

*Load Start Delay: Adjustable delay allows large motors to start against high-inertia loads without tripping

*Wide Range: Four models available with trip points between 200 – 1600 amps

*Accepted Worldwide: Designed to meet UL, CUL, and CE requirements

Qualifying OEMs can request no-cost test and evaluation units. For application notes and a helpful white paper on current sensing, visit the NK Technologies website at
