MTBF and Life Cycle are both indicators of reliability. MEAN WELL uses MIL-HDBK-217F as the core of MTBF. An expected reliability is forecasted through accounting component's number (exclude fans). The exact meaning of MTBF is after continuously using of power supply in a certain time, the probability of operating properly is 36.8%(e-1=0.368). If power supply is continuously used at double the MTBF time, the probability of operating properly becomes 13.5%(e-2=0.135). 
Life Cycle is found through using the temperature rise of electrolytic capacitor to estimate the approximate life of power supply. For example, SP-750-12 MTBF=769.3K hours; electrolytic capacitor C108 Life Cycle=202.2K hours (Ta=45° C)

Why the input voltage marked Spec sheet is 88~264 VAC but label is 100V~240VAC ?
During safety verification process, the agency will use a stricter standard -- ±10%(IEC60950 uses +6%, -10%) of the input voltage range labeled on the power supply to conduct the test. So, operating at the wider input voltage range as specified on the spec. sheet should be fine. The narrower range of input voltage labeled on the power supply is to fulfill the test standard of safety regulation and make sure that users insert input voltage correctly.

How do we choose a power supply to charge a battery?

 FuYuan has a wide range for battery charger purpose (0.25~250W). If these series does not meet customers' demands and they like to choose a power supply as a charger, we advice to pick up one which over load protection (OLP) mode is constant current limiting. The models in this mode provide constant current even when the protection circuit is triggered. 
The second choice is fold-back current limiting or constant wattage model. In this model, when a battery is running low, the output current of the power supply will gently increase. The level of increase depends on battery's capacity and degree of exhaustion. 
Hiccup or shut down model are not recommended because it will stop to generate current when OLP happens.

Notes on choosing a switching power supply?

To increase the reliability of the switching power supply (S.P.S.). we suggest users choose a unit that has a rating of 30% more power than actual need. For example, if the system needs a 100W source, we suggest that users choose a S.P.S. with 130W of output power or more. By doing this, you can effectively boost the reliability of the S.P.S. in your system. 
We also need to consider about ambient temperature of the S.P.S. and whether there is additional device for dissipating the heat. If the S.P.S. is working in a high temperature environment, we need to make some derating to the output power. The derating curve of "ambient temperature" versus "output power" can be found on our spec sheets. 
Choosing functions based on your application: 
Protection function: Over Voltage Protection (OVP), Over Temperature Protection (OVP), Over Load Protection (OLP), and etc. 
Application function: Signaling Function (Power Good, Power Fail), Remote Control, Remote Sensing, and etc. 
Special function: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS) function. 
Make sure that the model qualifies for the safety standards and EMC regulations you need.
