技術參數(shù)：LDMTR-01 ABB 進口電源接口模塊
電源模塊的作用就是電壓的轉換，它可以將交流或直流電變換成你所需要的交流或直流電。如:將市電220V交流電(AC)轉換成5V直流電(DC)，因為交流220V的電是高壓電，而電子產(chǎn)品是低壓供電的，這就需要一個轉換裝置，將交流220V的電壓轉換成低壓。再比如在機動車里有時需要轉換成220V交流電來使用，那么這會就成了低壓轉高壓了，因為機動車的電壓一般都比較低。
簡而言之就是類似手機充電器一樣，你的手機沒電了，要插電或充電才能正常使用，但是你不能直接接220V使用，因為這樣手機就會燒毀，因此就需要一個專門的轉換裝置來轉換成手機所需的電壓。
二、如何選擇合適的電源模塊
1、電路設計原理和工藝
電路原理的好壞分辨通常只能從專業(yè)角度著手?，F(xiàn)階段電源模塊大體可分為裸板和灌封兩種，裸板可以根據(jù)直觀的方式，如電子元器件的布局合理整齊有序、大方、有序、焊點亮凈挺拔。而灌封式模塊，就沒法查毛內部的情況，但是由于不外露，在安全性和性能指標層面要好很多。焊接工藝可包括手工焊接與波峰焊工藝，機械化生產(chǎn)的波峰焊工藝品質要優(yōu)于手工焊接。
2、芯片的元器件
電源的核心就是IC，它猶如電源的大腦一樣，IC的好壞直接影響著電源的各項參數(shù)。
3、變壓器元器件
決定電源的功率、耐溫等則是變壓器。變壓器負責完成交流電-直流電，能量超載就會飽和炸機4、電解電容和陶瓷電容
電解電容，和獨石膽電解電容，它采用硫酸做絕絳介質，可以將較大的容量做成較小的體積，并在上面標有+的符號，有的標有-的符號，一般做低頻交聯(lián)和旁路濾波用，缺點是介子損耗大一些，獨石電解電容，由于采用特殊的材料，性能優(yōu)于普通電解，頻率特性較好，但容量不能做的太大，可用于精確地電路中，如振蕩、或定時電路。
陶瓷電容有瓷介電容、瓷片電容、瓷管電容、陶瓷半可變電容幾種。主要是無極性，介質材料較好，容量不能做的太大。適用高頻電路。
The role of the power module is the conversion of voltage, which can convert AC or direct current into the AC or direct current you need. For example, the mains 220V alternating current (AC) is converted into 5V direct current (DC), because the AC 220V electricity is high voltage, and the electronic products are low voltage power supply, which requires a conversion device to convert the AC 220V voltage into low voltage. For example, in the motor vehicle sometimes need to be converted to 220V alternating current to use, then this will become a low voltage to high voltage, because the voltage of the motor vehicle is generally relatively low.
In short, it is similar to a mobile phone charger, your mobile phone is out of power, to plug or charge to normal use, but you can not directly connect to 220V use, because the mobile phone will burn, so you need a special conversion device to convert the voltage required by the mobile phone.
Second, how to choose the right power module
1. Circuit design principle and process
The distinction between good and bad circuit principles can usually only be made from a professional perspective. At this stage, the power module can be divided into bare board and potting two kinds, the bare board can be based on intuitive ways, such as the layout of electronic components is reasonable and orderly, generous, orderly, and the solder joint is bright and clean. The potting module can not check the internal situation, but because it is not exposed, it is much better at the level of security and performance indicators. Welding process can include manual welding and wave welding process, mechanized production of wave welding process quality is better than manual welding.
2, chip components
The core of the power supply is IC, it is like the brain of the power supply, the quality of the IC directly affects the parameters of the power supply.
3, transformer components
The transformer determines the power and temperature resistance of the power supply. Transformer is responsible for AC - DC, energy overload will saturate the machine 4, electrolytic capacitors and ceramic capacitors
Electrolytic capacitors, and monolith electrolytic capacitors, which use sulfuric acid to do the cording medium, can make the larger capacity into a smaller volume, and marked with the + symbol above, and some marked with the symbol -, generally do low-frequency crosslinking and bypass filtering, the disadvantage is that the meson loss is larger, monolith electrolytic capacitors, due to the use of special materials, performance is better than ordinary electrolysis, frequency characteristics are better, However, the capacity can not be too large, and can be used in precise circuits, such as oscillation, or timing circuits.
Ceramic capacitors include ceramic dielectric capacity, ceramic capacitor, ceramic tube capacitor and ceramic semi-variable capacitor. It is mainly non-polar, the medium material is better, and the capacity cannot be too large. Suitable for high frequency circuits.
