A SMPS (switched-mode power supply) is a power supply that uses a switching regulator to convert electrical power efficiently. SMPSs are commonly used in electronic devices such as computers, televisions, and mobile phones. To ensure that a SMPS is functioning properly, it is important to check it regularly.
There are several reasons why it is important to check a SMPS. First, a faulty SMPS can damage other components in an electronic device. Second, a faulty SMPS can cause an electronic device to malfunction or even become a fire hazard. Third, checking a SMPS can help to identify potential problems before they become serious.
