Kebolehpercayaan adalah penunjuk utama peralatan bekalan kuasa penyongsang komunikasi, dan komunikasi yang tidak terganggu mesti dijamin oleh bekalan kuasa komunikasi terlebih dahulu.

The reliability of the rack inverter reflects the comprehensive technical level of the equipment, including components, materials, circuit technology, thermal design, electromagnetic compatibility (EMC) design, manufacturing process, quality control, Penyongsang Gelombang Sinus Tulen Rumah. The reliability index put forward by our country in the "General Technical Requirements for the Power System of the Communication Bureau Station" is: during the operation of the system, masa purata antara kegagalan (TMTBF) should not be less than 5 Bekalan kuasa penyongsang 48Vdc 230Vac 1-10KVA penyongsang ac ke dc 10"h. With the development of communication equipment, this requirement is also The standard should be further improved, so the concept of availability is introduced. The difference between availability and reliability is that: reliability R refers to the probability that the equipment will not fail within a specified time; availability A refers to the effective operation of the equipment within the specified time. percentage of time.
