BCU2000 power modules, access to power transformer input 220V, 50Hz power supply voltage range of + 15% to -20%, the power supply module 13.8V, at 0 ~ 2A circumstances vary ± 2%, the motherboard provides a variety of security products and 12V / 7Ah lead acid battery mention DC power supply and automatically switch when AC power from the battery, the maximum output current: 2A.
No. Project Technical parameters and functions
1 AC input 1 AC22V, 50Hz AC input connector power transformer
2 Exchange instructions 1 LED2 color indicator lights green when there is electricity, while ACTEST output high; mains when the battery supplies power red, and the output low ACTEST
3 Battery indicator 1 LED1 red battery indicator, when relying on battery power, the battery voltage is lower than 11.3V, LED1 light, indicating the need to replace the battery, while the output low BATEST
4 Battery Testing A battery test home side interface, connect the device to detect the AC interface detects battery operation
5 AC detection An AC detection interface to connect the AC detection equipment interface module detects the power mains status
6 DC power output 5 groups DC output connector to power the device
7 DC input A switching power supply DC input interface, external load requires access to DC power supply is greater than the rated value and replace the fuse, in the case of 13.8V Maximum output current up to 5A
8 Battery Interface A battery interface to connect the backup battery, the battery charging system without mains power supply
9 Restore power After a touch switch SW1, replace the battery completed, touchdown SW1, BCU2000 to work the external power supply
