Switching Transformer


Switching power supply is named after its ability to achieve stable DC output by controlling the on-off time of the switch tube.

Product Description


Switching power supply is named after its ability to achieve stable DC output by controlling the on-off time of the switch tube. Due to its high frequency operation, it has considerable advantages over traditional linear power sources and is widely used as a power solution for many fields such as home appliances, industrial and mining equipment, communication, lighting, and other equipment. Its advantages mainly lie in: 1. Low power consumption and high efficiency, which also makes the overall internal temperature of the power supply controllable and relatively low, greatly extending its lifespan and enabling the overall equipment to handle temperature rise requirements well. Its efficiency can reach over 80, and even up to 95% for high-power applications. 2. Small size and light weight. Due to the operating frequency of the power switch tube and transformer being above 50KHz, both the transformer and heat sink can be significantly reduced, saving a lot of resource costs and reducing weight, resulting in significant savings in logistics costs. Based on this switch power supply, it is increasingly recognized in usage scenarios and continuously promoted.
