(3)LLVD: Load Low VoltageDisconnection. Once the AC input faildown, the battery discharging and thevoltage come down to the LLVDvoltage such as 44V, then the loadconnected to the LLVD contactor willbe disconnected to protect the BLVDload.
(4)BLVD: Battery Low VoltageDisconnection. Once the AC inputbroken down and LLVD contactor isdisconnected, the battery voltage stillgoes down to the BLVD voltage suchas 43.2V,then the load connected tothe BLVD contactor will bedisconnected to protected the battery.
Notice: Load connected to BLVD isnot battery, but the important loadsuch as transport or optical telecomequipment. Generally the power ofBLVD load is smaller than the powerof LLVD load.
