5A Over-Current Protection 12V Relay Module 

350.00 340.00

This set is ideally suited to over-current protection to your project. This module lets you control a second voltage using the current detected in a wire. Combining a current sensor and relay, the current can be measured and compared against a trigger pulse.

This set is ideally suited to over-current protection to your project. 5A Over-current protection Sensor module uses current transformer to collect the AC signal to achieve the relay over-current signal output within 0-5A range. Relay pull while over-current, relay released while not over-current. Users can use the relay COM, NC, NO three ports to control the external circuit on and off, in order to achieve over-current protection. If it exceeds it the relay will trigger.A trigger current can be set using the onboard potentiometer. Once selected on reaching the trigger current the relay will be activated. This module contains a single channel relay module which can be used to activate up to 250V AC and 30V DC.
