What is MTBF? Is it distinct from Life Cycle?
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.
