Airbridge BTS3612A CDMA Base Station
I. Configuration of battery subrack
The battery subrack can be installed with the batteries or DC lightning protector / DC
filter.
If batteries are installed, the subrack can hold a -48V/65Ah battery group containing
four 12V/65Ah storage batteries connected in serial.
If the battery cabinet is installed, only the DC lightning protector and the DC filter are
configured in the built-in battery subrack.
II. Configuration of battery cabinet
The battery cabinet can hold a –48V/650Ah battery group containing twenty-four
2V/65Ah storage batteries connected in serial.
If an air conditioner is used to control the temperature, a -48V/650Ah battery group
can maintain the normal operation of the BTS in S(2/2/2) configuration (with nine

8.3.2 Temperature Control Device

Either an air conditioner or a heat exchanger can be used for the temperature control,
and the configuration principle is as below.
When an air conditioner is adopted, the operational environment temperature can be
-40 ~ +55
temperature can be -40 ~ +45
I. Air conditioner
Two models are available, respectively supporting the local mains of 110V AC and
220V AC.
II. Heat exchanger
Two models are available, respectively supporting the local mains of 110V AC and
220V AC.
