AC Current Detection Sensor Module 5A 12V – Overcurrent Protection Switch Relay Output for Industrial Equipment, 20Hz-400Hz Frequency Range

Specifications:Item Type: AC Current Detection Sensor ModuleWorking Voltage: DC12VWorking Current: <20MAOperating Frequency Range: 20Hz-400HzOutput Mode: Switch signal outputMounting Hole: Hole Diameter: Approx. 3mm(0.12in) / 0.12inMaximum Detection Wire Diameter: Approx. 5.2mm(0.20in) / 0.20inSize: 44 * 38 * 20mm(1.73 * 1.50 * 0.79in)Color: BlueWorking Environment: -40℃~+85℃, 0-95%RHInstruction for Use:Set the over-current protection point by adjusting the potentiometer. Turning the potentiometer clockwise reduces the detected current. The method is as follows:1. Pass the wire to be measured through the current transformer, and connect VCC and GND to a DC12V power supply2. Adjust the potentiometer. When the sound of the relay pulling in is heard (a multimeter can be used to measure whether COM and NO are connected. If connected, it indicates that the relay has pulled in), then reduce or cut off the current flowing through the wire to be measured. If the relay releases at this time, it indicates that the over - current protection point has been found (a multimeter can be used to measure whether COM and NC are connected. If connected, it indicates that the relay has released)3. If the relay does not release when reducing or cutting off the current flowing through the wire to be measured, it means that the potentiometer still needs to be adjusted to find the over - current protection point.Package List:1 x AC Current Detection Sensor ModuleNote:1.
