SURFACE POWER SUPPLY UNIT
Summa’s surface power supply unit
(PSU) contains two power supply
units which are supplied with AC
power by two independent male IEC
inlets. These dual power supplies
provide full power redundancy, a
feature of all Calrec products.
It is recommended that, to ensure power
redundancy, these two IEC inlets should
be supplied by separate AC power
supplies.
Although Summa will run with only one
PSU powered on, it is recommended that
both IECs are connected and powered
up to ensure power redundancy. A PSU
failure or a loss of AC power input will
generate a system status error message
(See the Summa User manual for more
information on system status monitoring).
If one PSU fails, the other will
automatically take over with no loss of
audio or operation.
ConnectingtheSurfacePSU
The AC/DC surface PSU connects as a
single unit to the rear of the console. Two
dowelling rods and two keyhole studs act
as guides to ensure the PSU module fits
correctly into the power inlet. The Surface
power inlet is a SAMTEC MPSC plug and
the surface PSU connects via a SAMTEC
MPSC socket. A single latch locks the
surface PSU in place and a large handle
provides an easy way to support it during
connection and disconnection.
Two air vents along the top of the PSU
module line up with air vents in the main
chassis, allowing increased air flow and
temperature control through the rear of
the console. Air vents should be kept
clear at all times when the console is in
operation.
DisconnectingtheSurfacePSU
Instructions for safely disconnecting the
surface PSU can be found on the rear of
the console, as shown on the next page.
PowerDistribution
The power supply module connects to
an internal PSU connector board which
supplies 48 V DC power to Summa’s
internal components. The PSU connector
board also includes reset and system
PSU UNIT FRONT VIEW
monitoring connections for each internal
component. Each DC power outlet is
fitted with its own 1.85A self-resetting
fuse.
The Meter Display and Touch Display
are powered (5 V) via their connections
to their CPU cards. Each Meter Display/
Touch Display also has a backlight which
is powered via a separate 12 V DC
connection from their CPU cards.
