Switching Power Supply 12V 3A

Description 

48V 2A power supply,the switching power supply uses the principle of pulse width modulation. The control mode is to control the on-off of the switching devices of the inverter circuit, so that the output end can get a series of pulses with equal amplitude, which can be used to replace the sine wave or the required waveform.

Multiple pulses are generated in the half cycle of the output waveform, so that the equivalent voltage of each pulse is sinusoidal waveform, and the output is smooth and less low-order harmonics. Modulating the width of each pulse according to certain rules can not only change the output voltage of the inverter circuit, but also change the output frequency.

Material characteristics of power adapter housing

1、 ABS material properties

ABS is a thermoplastic polymer material structure with high strength, good toughness and easy processing. It can perform normally in the environment of - 25 degrees - 60 degrees, and has good formability. The processed product has a smooth surface and is easy to dye and electroplate. Performance characteristics of ABS materials

1. Low strength, tensile strength 43mpa, bending strength 79mpa

2. It is not temperature resistant, and the long-term service temperature shall not be higher than 60 ℃

3. Good fluidity, coloring, surface spraying and electroplating properties. ABS materials are used in household appliances, panels, masks, assemblies, accessories, etc., especially household appliances, such as washing machines, air conditioners, refrigerators, electric fans, etc. In addition, it is widely used in plastic modification.

2、 PC material properties

1. With high strength and elastic coefficient, high impact strength and wide temperature range

2. High transparency and free dyeing

3. H.d.t. high

4. Good fatigue resistance

5. Good weather resistance

6. Excellent electrical characteristics

7. Tasteless and odorless, harmless to human body, in line with health and safety

8. The defects of low forming shrinkage and good dimensional stability are that the poor design of formed products is easy to produce internal stress problems

Application: Switching power supply 12V 3A for electronic and electrical appliances: CD, switch, home appliance shell, signal tube, telephone steam

Car: bumper, distributor, safety glass industrial parts: camera body, machine shell, safety helmet, diving goggles, safety lens, there are plastics that can not be broken by hammer. Ordinary PC may not meet the requirements, so it is necessary to use high-grade engineering plastics. 3、 ABS + PC material properties

The synthetic materials of ABS and PC have the characteristics of the former two. They have excellent forming and processing properties, good fluidity and high strength. ABS + PC material is easy to process, has good dimensional stability and surface gloss, is easy to paint and color, and can also carry out secondary processing properties such as metal spraying, electroplating, welding and bonding. Because ABS combines the characteristics of its three components, it has excellent comprehensive performance and has become one of the preferred plastics for electrical components, household appliances, computers and instruments.
