How long is the shelf life of outdoor power supply

How long does a power supply last?

One of the most common types of power supplies are those used in computers. On average, a power supply in a computer can last anywhere from 2-5 years. However, it's important to note that this lifespan can be significantly impacted by the quality of the power supply, the operating conditions, and the usage of the computer.

What is the life expectancy of a power supply?

No general answer can be given. Well, the power supplies' heating is usually much higher at 90% than at 80% and extremely high at 100%. So considering heating, it's usually good not to put more than 80% load on the supply for longer periods. Life expectancy is not really equal to MTBF!

How long does a CPE power supply last?

The typical lifetime expectation for a CPE power supply is between 5 or 10 years and many operators require that power supplies are designed to follow the IPC9592B standard which sets out two performance levels: Class I – 5 years life with 40C ambient, 80% of rated load – applies to general or standard, e.g. consumer Telco applications.

How long does an external AC/DC power supply last?

The lifetime of a typical external AC/DC power supply is determined by the Electrolytic capacitors (E-caps). Whilst other components e.g. opto-couplers can also deteriorate over time they seldom dictate the product life to the same level as the E-caps. E-caps wear-out over time as their electrolyte dries out.

What factors affect the lifespan of a power supply?

The quality of the power supply is one of the most important factors that can affect its lifespan. A high-quality power supply will be made with better components and be more durable than a lower-quality power supply. This means that a high-quality power supply is more likely to last longer and be more reliable.

How long does a TDK rws50 power supply last?

TDK RWS50 power supply lists the MTBF at 4,170,949 hours !!!, which is about 500 years. Yet they contain mechanical fans that usually have at most 40,000 hrs, and best electrolytic caps are rated at 100,000 hours at 60C. Although the life expectancy doubles with every 10c drop in operating temperature, I still can't figure out the 4M hrs rating.
