In today's booming development of the communication industry, 통신 전원 공급 장치 제조 산업의 경쟁이 심화되었습니다. 일부 주요 기업 외에도, there are also some small and medium-sized manufacturers' products also integrated into the market. The focus of competition is still price, and some people often confuse low price with cost-effectiveness, and there is inevitably a quality problem behind it. The following aspects should be paid attention to when selecting a communication power supply.

(1) Quality and service
Generally speaking, most of the regular inverter power supply manufacturers have passed ISO9000 certification, product development and production have established strict quality control process, product quality is guaranteed, product continuity is also long, future maintenance and spare parts supply Guaranteed. 하지만, the service of regular manufacturers is also uneven. Although some manufacturers have a very good service attitude, due to the poor quality of the products and continuous failures, users do not want this. 그러므로, both quality and service must be provided.

(2) The comprehensive index of the product is better
It is not difficult to make one or two indicators of the product good. If all indicators are good, it is inseparable from excellent circuit design ideas and components, and the quality assurance of devices is also inseparable from good process and process control. The comprehensive index is of great significance to ensure the normal operation of the communication circuit.

(3) Product price
The price of inverter power supply has always been a very sensitive topic for people. In the concept of "value for money", don't think that low price means good "value for money". In order to ensure good comprehensive indicators, high-quality products, select high-quality components and use sophisticated technology, their production costs will not be lower than low-end products, and the comprehensive factors of performance and price are the correct positioning for judging products. The purpose of users adopting power supply equipment is to provide power and guarantee for communication equipment and network. Especially in important links and information centers, power failures will cause irreparable losses and adverse effects. It is recommended to fully consider and choose carefully when purchasing power supply products.
