2.4 System Components
The Aspiro system components are described below and in later chapters of the manual.
2.4.1 System Controller
As standard the system operates without a controller. A cover plate must be installed
when using no controller to protect against injuries. The system can also be controlled
by the ACC Extended (ACX) or PCC controller. The description and operation of these
controllers is covered in separate manuals which are available at:
ACC Extended (ACX): http://www.unipowerco.com/pdf/acc-man.pdf
PCC: http://www.unipowerco.com/pdf/pcc-man.pdf
The system can be remotely managed using UNIPOWER’s PowCom™ which works in
conjunction with the controller. This is covered in its own manual which is available at
http://www.unipowerco.com/pdf/powcom-man.pdf.
2.4.2 DC Distribution
DC Distribution consists of 1 x 40A battery and 4 x 15A load breakers.
The distribution unit is designed for switching the battery and load on and o.
The battery and load breakers are supervised by measuring the voltage drop across each
breaker. In the case of load breakers, those which are not connected to any load will not
cause a breaker alarm even if they are left open.
A battery fuse alarm is generated after the battery voltage drops below a certain level,
depending on the actual battery capacity and condition.
2.4.3 Low Voltage Battery Disconnect (LVBD)
The system is equipped with a low voltage battery disconnect which prevents the
batteries from deep discharging, thus prolonging the battery life. The disconnect requires
a detected mains failure at the supervision unit (controller).
If disconnection occurs, the batteries will not supply power to the load until they have
been recharged to a set voltage level, which can be adjusted by the user.
If disconnection occurs, the batteries will be reconnected when the mains supply returns.

Manual No. PM110-6500-00 rev-2a
PM110-6500-00-rev2a-0117.indd
2.4.4 Rectier Module
The Fan-Cooled XPGe12.48 (1200W), XR08.48 (800W) and XR04.48 (400W) rectiers
are modular power supplies designed for parallel operation and hot-plug installation in
the Aspiro Power Systems.
CAUTION Do not mix rectier types in a single system.
Each rectier provides extremely reliable DC power in a very high density. The module
incorporates power monitoring through an internal microprocessor, giving up to the
second updates to the system controller and companion rectiers. This guarantees
tightly controlled load sharing among rectiers, and provides status and identication
information to the controller.
The rectiers operate in parallel using active load sharing. They incorporate soft-start
at both the input and the output, which protects against high incoming and outgoing
currents. The output voltage of the rectier is automatically adjusted to the required
voltage by the controller.
Figure 2-2 XPGe12.48 and XR04.48/XR08.48
XPGe12.48 rectiers cannot be used in the same rack as XR04.48 / XR08.48 rectiers.
