2.產 品 詳 情 資 料：
RELIANCE 355C22D電池的壽命非常依賴于電路板的環境溫度和通電占空比。RELIANCE 355C22D嵌入式控制器上提供的鋰電池應在電路板斷電且環境溫度為40°C的情況下提供至少兩年的備份時間。如果通電占空比為50%（電路板一半時間通電），則電池壽命為四年。在較低的環境溫度下，RELIANCE 355C22D備份時間大大延長，并可能接近電池的保質期。存儲板時，應斷開電池以延長電池壽命。這在高環境溫度下尤為重要。控制器出廠時電池已斷開（即VMEbus+5V備用電壓被選為主電源和輔助電源）。如果您打算將電池用作電源（無論是主電源還是輔助電源），在安裝模塊之前，有必要重新配置J20上的跳線。有關可用跳線配置，請參閱第2章中的SRAM備用電源選擇頭J20。RELIANCE 355C22D
The life of the battery is very dependent on the ambient temperature of the board and the power-on duty cycle. The lithium battery supplied on theRELIANCE 355C22D Embedded Controller should provide at least two years of backup time with the board powered off and with an ambient temperature of 40° C. If the power-on duty cycle is 50% (the board is powered on half of the time), the battery lifetime is four years. At lower ambient temperatures the backup time is greatly extended and may approach the shelf life of the battery. When a board is stored, the battery should be disconnected to prolong battery life. This is especially important at high ambient temperatures. The controller is shipped with the batteries disconnected (i.e., with VMEbus +5V standby voltage selected as both primary and secondary power source). RELIANCE 355C22DIf you intend to use the battery as a power source, whether primary or secondary, it is necessary to reconfigure the jumpers on J20 before installing the module. Refer to SRAM Backup Power Source Select Header J20 in Chapter 2 for available jumper configurations.RELIANCE 355C22D
