Label:Yes
3,Relay Status Indication:The relay remains closed during overcurrent conditions and opens when the current returns to the normal range.
2,Product Parameters: Working voltage is DC12V, working current <20MA, working frequency range is 20Hz-400Hz, output mode is switch signal output.
1,Current Transformer-Based Detection:This module utilizes a current transformer to monitor AC signals within 0-5A, triggering a relay output when overcurrent is detected.
5,Simple Installation:Includes 3mm mounting holes and supports wire detection with a maximum diameter of 5.2mm.
4,Overcurrent Protection: The user can use the three ports of the relay's COM, NC and NO to control the on and off of the external circuit, so as to realize the overcurrent protection function.

Instruction 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 supply.
2. 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.
