The LED driver we mentioned includes digital driver and analog driver. Digital driver refers to digital circuit driver, including digital dimming control, RGB full-color change, etc. Analogue drive refers to analog circuit drive, including AC constant cur

Touch the surface of the power module. It's warm. Is the module broken? Wait a minute, there is a little fever, just because it is working hard. However, high temperature has a great impact on the reliability of the power module! Based on the knowledge o

Power failure accounts for the majority of electronic equipment failures in electrical troubleshooting. Therefore, being familiar with the common faults and maintenance skills of switching power supply will help shorten the maintenance time of electronic

The current through the transformer (and switch tube) increases nonlinearly when the machine is started under high voltage or low voltage input (including light load, heavy load, capacitive load), output short circuit, dynamic load, high temperature, etc.

An important reason for the low life of LED drive power supply is that the life of aluminum electrolytic capacitor required for the drive power supply is not enough. The main reason is that the ambient temperature inside the LED lamp is very high during l
