<p>Current Sensors are devices that detect electric current (AC or DC) in a wire, and generates a signal proportional to it. The generated signal could be analog voltage or current or even digital output. The CS series digital current sensors provide logic level output that changes from approximately Vcc to 0.4 volts when the sensed current exceeds the operate point. They are used in a variety of applications such as variable speed drives, overcurrent protection, ground fault detectors, UPS and telecommunication power supplies, automotive - battery management systems, and wattmeter's.</p><p>The CSDA1BA Ac Current Sensor features AC or DC current sensing with digital output. This Honeywell current sensor is accurate and low cost with minimum energy dissipation and maximum current limited only by conductor size.</p>
