24v 3a Switching Power Supply
The power supply with a fan mainly relies on forced air cooling for heat dissipation; and the air in the sealed box cannot convect with the outside, which will greatly increase the ambient temperature inside the box.
- Product Introduction
Introduction
With the rapid development of semiconductor technology, especially the wide application of large-scale integrated circuits, electronic equipment is developing in the direction of miniaturization and solid state. At the same time, higher requirements are placed on the power supply equipment. 24v 3a Switching Power Supply is made with electronic components and a small high-frequency transformer. Its working principle is that high-voltage electricity (mains 220V) is directly converted into high-voltage DC by diodes, and then converted into high-frequency and low-voltage pulse power through a high-frequency switching circuit. After diode rectification and capacitor filtering, a smooth low-voltage DC output is formed.
Features
24v 3a Switching Power Supply is often used in LED light boxes. Therefore, we pay great attention to whether the customer's light box is sealed and whether the power supply bottom case is close to the box. The sealed box mainly relies on heat transfer and radiation to dissipate heat while the sealed box mainly relies on air convection to dissipate heat. We advise customers not to use power supplies with fans in sealed boxes. The power supply with a fan mainly relies on forced air cooling to dissipate heat, and the air in the sealed box cannot convect with the outside world, which will greatly increase the ambient temperature in the box. Higher ambient temperature will further lead to lower conversion efficiency. In addition, our products are made of metal materials and have a hollow design, so it is very good for heat dissipation. The design of multiple protection functions also ensures the safety of the circuit.
