In today's booming development of the communication industry, ការប្រកួតប្រជែងក្នុងឧស្សាហកម្មផលិតកម្មការផ្គត់ផ្គង់ថាមពលនៃការផ្គត់ផ្គង់ថាមពលបានកាន់តែខ្លាំងឡើង. បន្ថែមលើសហគ្រាសសំខាន់ៗមួយចំនួន, there are also some small and medium-sized manufacturers' products also integrated into the market. ការផ្តោតអារម្មណ៍នៃការប្រកួតប្រជែងនៅតែជាតម្លៃ, and some people often confuse low price with cost-effectiveness, ហើយមានបញ្ហាគុណភាពនៅពីក្រោយវា. The following aspects should be paid attention to when selecting a communication power supply.

(1) គុណភាពនិងសេវាកម្ម
និយាយជាទូទៅ, 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. យ៉ាងនាក៏ដោយ, សេវាកម្មរបស់ក្រុមហ៊ុនផលិតជាប្រចាំក៏មិនស្មើគ្នាដែរ. ទោះបីជាក្រុមហ៊ុនផលិតមួយចំនួនមានអាកប្បកិរិយាសេវាកម្មល្អក៏ដោយ, due to the poor quality of the products and continuous failures, users do not want this. ហេតុដុចនេហ, both quality and service must be provided.

(2) សន្ទស្សន៍ដ៏ទូលំទូលាយនៃផលិតផលគឺប្រសើរជាង
វាមិនពិបាកទេក្នុងការធ្វើសូចនាករមួយឬពីរនៃផលិតផលដែលល្អ. If all indicators are good, វាមិនអាចបំបែកបានទេពីគំនិតរចនានិងសមាសធាតុដ៏ល្អឥតខ្ចោះ, and the quality assurance of devices is also inseparable from good process and process control. សន្ទស្សន៍ដ៏ទូលំទូលាយគឺមានសារៈសំខាន់យ៉ាងខ្លាំងដើម្បីធានាបាននូវប្រតិបត្តិការធម្មតានៃសៀគ្វីទំនាក់ទំនង.

(3) តម្លៃផលិតផល
The price of inverter power supply has always been a very sensitive topic for people. នៅក្នុងគំនិតនៃ "value for money", កុំគិតថាតម្លៃទាបមានន័យថាល្អ "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, ហើយកត្តាដ៏ទូលំទូលាយនៃការអនុវត្តនិងតម្លៃគឺជាទីតាំងត្រឹមត្រូវសម្រាប់ការវិនិច្ឆ័យផលិតផល. 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.
