2.3.3 Rectier Module
The Fan-Cooled XPGe12.48 (1200W), XR08.48 (800W) and XR04.48 (400W) rectiers
are modular power supplies designed for parallel operation and hot-plug installation in
the Aspiro Power Systems.
Each rectier 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 rectiers. This guarantees
tightly controlled load sharing among rectiers, and provides status and identication
information to the controller.
The rectiers 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 rectier is automatically adjusted to the required
voltage by the controller.

XPGe12.48 rectiers cannot be used in the same rack as XR04.48 / XR08.48 rectiers.
CAUTION XPGe12.48 rectiers cannot be used in the same system as XR04.48/
XR08.48 rectiers.
