(FPAA and FPBA) description
3.1

Flexi Power Module (FPMA) and sub-modules (FPAA and
FPBA/B) operation
Flexi Power Module (FPMA) is an optional module. In a BTS site with AC feed only, a
Flexi Power Module (FPMA) is required for converting the AC to DC before feeding the
DC power to the System Module. It comprises FPMA mechanics and AC and DC interfaces. The actual power sub-modules are the following:
•
•

Flexi Power AC/DC sub-module 200-240 V AC (FPAA)
Flexi Power Battery sub-module (FPBA)

The maximum number of sub-modules in an FPMA is four.
For installation instructions, see section Installing Flexi Power Module (FPMA) in the
Installing Flexi Multiradio BTS GSM/EDGE Optional Items document.
The FPMA is presented in the following figures.

Flexi Multiradio BTS GSM/EDGE Optional Items Description

FPMA: full configuration with two FPAAs and two FPBAs

For examples of how many FPMAs are required for common configurations, see section
Common configurations in Creating Stack, Wall and Pole Configurations for Flexi Multiradio BTS GSM/EDGE, Creating FCIA Configurations for Flexi Multiradio BTS
GSM/EDGE and Creating FCOA Configurations for Flexi Multiradio BTS GSM/EDGE.
The FPMA can support 1-phase and 3-phase AC input. The nominal input voltage is
200-240 V AC (the operating voltage range is 180 - 276 V AC). The maximum output
power from the FPMA is 4kW (with 4 FPAAs).
Flexi Power AC-DC sub-module (FPAA)
The main function of the FPAA is to provide the BTS with nominal 48 V DC power from
an AC supply. Maximum DC output power of one FPAA module is 1000 W. A nominal
48 V DC supply is intended for BTS internal use only (a nominal 48 V DC supply is not
intended for 3rd party equipment because they may require lower conducted emission
level than EN55022 Class A). The FPAA includes its own integrated self-controlled fan.
In case the fan fails, an alarm is generated and the FPAA has to be replaced (the fan
alone cannot be replaced).


!
Risk of thermal runaway of the battery, because temperature compensation of charging
voltage is not supported. Do not connect an external lead acid battery for longer backup
times to a nominal 48 V DC supply.
The FPAA unit remembers the main control switch position. If the FPAA power is
switched to Standby, the power remains OFF after input voltage interrupt.
The stand-by switch is used for switching the FPAA unit ON/Stand-by when AC input
voltage has been connected to the FPAA unit.
Flexi Power Battery sub-module (FPBA/B)
The Flexi Power Battery Sub-Module (FPBA/B) is a separate optional sub-module used
together with the FPAA.

Flexi Multiradio BTS GSM/EDGE Optional Items Description

Flexi Power Module (FPMA) and submodules (FPAA
and FPBA) description

The FPBA/B provides short-term battery backup time when the AC power mains is down
on a Flexi BTS site. The FPBA is a lithium ion battery and the FPBB is a Lithium Ferrite
battery. The maximum DC output power from one FPBA/B module is 1000 W. The input

power for the BTS cannot exceed the maximum output power of the installed batteries.
Otherwise the batteries do not provide the BTS with the needed power during power
failure.
The power switch of the FPBA/B unit controls input power. Batteries can be drained by
the BTS if the power switch is set to OFF position.
The stand-by switch is used for switching the FPBA/B unit to ON/Stand-by when AC
input voltage has been connected to the FPBA/B unit.

g Do not install the FPBA and FPBB in parallel. If used in parallel, one of these two
battery types will discharge faster than the other causing an unbalance between the
batteries.

description
4.1

Flexi Power DC/DC Module (FPDA) operation
Flexi Power DC/DC Module (FPDA) is an optional stand-alone 2 kW DC/DC module.
The FPDA converts nominal 24 V DC input voltage (normally negative grounded) 53-55
V DC output voltage. The 53-55 V DC is then distributed to BTS loads. When the BTS
power load is more than 2 kW, multiple FPDAs can be installed in parallel. When FPDAs

are used in parallel, a maximum of two DC cables can be installed together at each
output terminal.
Conducted emission level of the 53-55 V DC supply is according to the standard
EN55022 Class A. The 53-55 V DC supply is intended for BTS internal use only (the 5355 V DC supply is not intended for 3rd party equipment because they may require lower
conducted emission level than EN55022 Class A).

!
Risk of thermal runaway of the battery, because temperature compensation of charging
voltage is not supported. Do not connect an external lead acid battery for longer backup
times to the 53-55 V DC supply.
The FPDA includes its own integrated self-controlled fan. In case the fan fails, an alarm
is generated and the fan has to be replaced.
For installation instructions, see section Installing Flexi Power DC/DC Module 24V
FPDA in the Installing Flexi Multiradio BTS GSM/EDGE Optional Items document.
