Overheat protection

A function that safely shuts down the equipment when a power supply device is placed in a no-ventilation or sealed condition, such as due to fan failure, and its temperature exceeds the specified limit. Normally, it is designed to detect abnormal temperatures and shut down by means of an overheat protection circuit. However, if an overheat protection circuit cannot be installed, the design must allow the device to fail and stop safely without causing adverse effects such as smoke or fire. In some cases, an alarm notifies users of the temperature abnormality, and the equipment is manually shut down.
