NK Technologies introduces DS1 DC Current Sensors. DS1 current sensors feature a compact and non-adjustable one-piece design to deliver reliable detection of very low DC current levels in a wide range of applications. Their compact and non-adjustable one-piece design simplifies installation, even in crowded control cabinets. DS1 current sensors can be powered by any DC voltage between 10- 28 volts and use the same circuit as the one being controlled, or a separate source of voltage to power the sensor as long as the circuit being controlled uses the same ground. This further simplifies installation and operation when compared with other current sensors.
