Description: The search sensor module is mainly used for current detection, overcurrent protection, short circuit protection, module needs test series in the current loop detection, since the shunt itself detect errors and drift op amp, the detection process may have error, module power supply circuit and measured current circuit is preferably independent of each other open, to avoid damage to the device interference and wiring errors, be sure to pay attention to, use reference wiring diagram we describe the method provided by the wiring process have questions, please contact our technical engineers use to communicate.
