AC Current Switches – AS1, ASX Series – NK Technologies


If you control or monitor electric-powered loads, you need current switches. Monitor fans, pumps, lights, and heaters for proper operation. Current switches give positive feedback that the load is operating and are much easier to install than alternatives like pressure switches, optical sensors, or zero-speed switches.

AS and ASX current switches combine a current sensor, signal conditioner, and limit alarm in a single package. AS1 series are well suited to automation systems of all kinds with their universal solid-state outputs and wide frequency response.  ASX series combines the AS3 design with a built-in adjustable time delay. All models feature high visibility LED indication and rugged construction. AC monitoring models are available in solid and split-core cases.
