Power
Supplies
5-V Models (Basic Block: S8TS-02505@)
Note 1. If set to less than −10%, the undervoltage detection function may operate. Ensure that the output capacity and output current after adjust-
ment do not exceed the rated output capacity and rated output current respectively.
2. The output current is specified at power output terminals.
3. Refer to the explanations of functions on page 28 for details.
4. Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.

Item Value Definition
Reliability (MTBF) 250,000 hrs min. MTBF stands for Mean Time Between Failures, which is calculated according to the probability of acci-
dental device failures, and indicates reliability of devices. Therefore, it does not necessarily represent the
life of the product.
Life expectancy 10 yrs min. The life expectancy indicates average operating hours under the ambient temperature of 40°C and a load
rate of 50%. Normally this is determined by the life expectancy of the built-in aluminum electrolytic ca-
pacitor.
