Why does the led power supply fail? Detailed explanation of 10 problems that may cause LED driver power failure October 28, 2024
Basically, it can be said that the main function of the LED driver power supply is to convert the input AC voltage source into a current source whose output voltage can vary with the LED Vf (forward conduction voltage drop). As a key component in LED lighting, the quality of the LED driver directly affect the reliability and stability of the overall lamps.
Class 2 VS Class II Power Supply October 28, 2024
When purchase ac dc power supplies, confusion often exists about the difference between Class 2 and Class II rated power supplies.

What is a LPS Power Supply? October 28, 2024
An LPS rated power supply is designed for safety reasons to conform to a maximum permitted output voltage, output current and output power rating. Regulatory agencies have created many designators for external power supplies which conform to different sets of specifications. The LPS (Limited Power Source) requirements are specified in the latest IEC 62368-1 and 60950-1 standard are used to define power

Why is the reliability of power supply important? October 28, 2024
A good ac adapter for hp monitor can make the computer work more stably, which seems reasonable on the surface. But when it comes to why to use a good laptop ac adapter charger, some users may be a little confused. The "good power supply" mentioned here does not necessarily mean buying an expensive switching power adaptor. In fact, some users choose a good power supply, but because the selected power supply does not match the load of the terminal equipment, the switching power supply is insufficient and the equipment is unstable.

What is a UL Listed Adapter October 28, 2024
A UL listed adapter is an AC adaptor that meets the safety standards outlined by the Underwriters Laboratories (UL). This is an organization that provides safety power supply certification for a wide variety of products include electrical devices, electronic equipment, building products, medical equipment, processed foods, water heaters and fire protection products. These universal ac to dc adapter are subjected to stringent testing and evaluation to ensure they meet UL’s criteria for performance and safety.

What is the difference between CQC certification and CCC certification? October 28, 2024
CCC certification is a national compulsory product certification, CQC certification is a national voluntary product certification, also known as logo certification, CQC is the abbreviation of China Quality Certification Center, which is also the main difference between the two certifications. In addition, there are differences in certification classification and product coverage.

PFC what does it mean? October 28, 2024
PFC (Power factor correction) is a feature included in power supply boxes that reduces the amount of reactive power generated, it mean to improve power factor, and therefore power quality. It reduces the load on the electrical distribution system, increases energy efficiency and reduces electricity costs. It also decreases the likelihood of instability and failure of equipment.
