The casing of a switching power supply is mainly made of aluminum material and produced into a mold using a die-casting machine. It has high waterproof function, tough texture, and is not easy to leak water, which can better meet the needs of customers. Our company specializes in producing power cases, charger cases, converter head cases, and LED power cases. The power cases have waterproof function and are made of natural synthetic rubber, with complete functions, good performance, and beautiful appearance. We can also manufacture cases that meet the specifications according to the needs of consumers, with high quality and low price.

The switch power supply casing has high reliability; High work efficiency; Design a soft start circuit to limit AC surge current; Long service life; Wide input voltage range, in line with global usage standards; Good insulation function and high electrical strength; Equipped with short-circuit, overload, and overvoltage protection functions; Advantages such as small size, light weight, and elegant appearance. After the switch speed improves, it will be affected by the distributed inductance and capacitance in the circuit or the stored charge in the diode, resulting in surges or noise This not only affects nearby electronic devices, but also greatly reduces the reliability of the power supply itself Among them, to prevent voltage surges that occur with the opening and closing of the switch, R-C or L-C buffers can be used, while magnetic buffers made of amorphous magnetic cores can be used for electric current surges caused by stored charges in diodes However, for high frequencies above 1MHz, resonant circuits should be used to make the voltage on the switch or the current passing through the switch sinusoidal. This can reduce switch losses and also control the occurrence of surges This switching method is called resonant switch. The casing of a switching power supply has the characteristics of high efficiency, wide operating temperature range, strong anti-interference ability, good electromagnetic compatibility, strong adaptability to the power grid, fast dynamic response, high stability, low noise ripple, and strong protection function And it has multiple protection functions such as short circuit, overload, overvoltage, etc.
