Leitch 6800/7000 series frames are designed to operate in an ambient
temperature range of 0° to 50°C (32° to 122°F). No special provisions are
necessary other than power loading limitations that should be
considered upon installation.
There are two separate issues to consider with respect to a serial digital
product and its related loading limitations: power supply load
limitations and maximum frame loading limitations.
Power Supply Load Limitations
These are the maximum suggested loading specifications of the power
supply over the operating temperature range 32°F - 122°F
(0.5°C - 50°C). The 6800 series of power supplies come with 120 VAC,
240 VAC, and 48 VDC with inputs -6.5 V and +6.5 V output. Do not

Chapter 3: FR-6804/FR-6804-1 Frames Overview
The GPI is made up of two parts:
• A fault sensing circuit within each power supply that monitors the
primary circuit and the two output voltages.
• A relay that provides isolation between Leitch equipment and the
GPI output connector at the rear of the frame.
There are three connections provided for GPI reporting:
•Normally closed (NC)
• Normally open (NO)
•Ground
To comply with SMPTE standards, the product uses the NC output and
ground. The relay has two states for GPI reporting:
• OPEN: An open output signifies that the GPI relay is activated and the
power supplies in the frame are present and operating correctly.
• CLOSED: A closed output signifies that the GPI relay has been
de-activated indicating an internal fault in either of the power
supplies or a loss of power to one or both of the supplies.

frame. Cool, ambient air is drawn in through the dust filter at the front of
the FR-6804(-1), passed through its modules, and then drawn up
through the frame slots and into the CF-6801 cooling frame. The hot air
is exhausted from the back through the use of a ten-fan array.
The CF-6801 cooling frame is mounted directly above the FR-6804(-1).
The CF-6801 frame requires 1.75 in. (44 mm) of rack space with a depth
from the mounting surface of 11 in. (280 mm).

Figure 4-1. Use of CF-6801 with FR-6804(-1)
Since each fan operates independently, the failure of one or two of the
fans does not impair the array’s cooling abilities or effectiveness. In order
to ensure maximum reliability under varying conditions of ambient
temperatures, Leitch Technology recommends employing the CF-6801
Cooling Frame in one of the configurations shown in Figure 4-1.
The cooling frame is DC-powered through the FR-6804(-1) using 22
AWG shielded twisted pair (or equivalent) cable. No AC power is
required for its operation. The CF-6801 cooling frame is designed to
ensure the best performance and longest service life from the
FR-6804(1) frame.

The green LED indicates that the buck
converter is regulating correctly, (that is 9.5 V
to 10 V are established across the fans). If the
voltage across the fans falls below 8.8 V, the
green LED turns off, the red LED turns on,
and the relay closes the contact for the GPI
output to indicate bad voltage regulation. The
green LED should always be lit to indicate
correct voltage across the fans.
This feature protects the power distribution
circuitry from over-voltage conditions,
starting at 15 V, up to a maximum of 19 V. If
such a condition occurs, the power to the
converter is removed, the red LED turns on,
and the relay closes the contact for the GPI
output.

Buck Converter Chapter 4: CF-6801 Cooling Frame
Buck Converter
The buck converter specifications are as follows:
V in (max.) 15 V
V out 9.5 V (3%)
Efficiency 96.4%
Frequency 100 KHz
Imax 1.1 A
The buck converter is protected against voltages in excess of 15 V by the
Zener diode D13 and by resistor R43. This structure clamps the voltage
across U3 in the case of an over-voltage. This protection is added as a
redundant fail safe measure in the event that the Over-Voltage Protection
(OVP) circuitry provided in the 6804PS fails to activate. U3 will not
regulate properly until the over-voltage condition ceases.
Over-Current (OC) and Under-Current (UC) Sensing
A 0.05 W sensing resistor across a window comparator gives a voltage
reading that indicates the current through the fans:
•Vsense = Rsense x Ifans
Vsense is then multiplied by the OP
resistors R16 and R18), to become:
• Vcompare = 174 x Vsense
This voltage is compared to the set limits which are approximately 5.1 V
and 7.5 V. It is an indication of an OC condition (there a short-circuit on
the distribution board) if Vcompare goes above the 7.5 V limit and an
indication of a UC condition (one or more of the fans is not working) if
Vcompare is below 5.1 V. Either of these conditions (OC or UC) will
cause the red error LED to illuminate and the relay will close (to make
contact for the GPI output). The expected average value of current draw
for the 10 fans is about 0.73 A. The sensing circuitry allows for about
20% tolerance on either side before triggering.

6801PS Power Supply Module
The model 6801PS power supply is a two-stage switching power supply
that provides the following outputs:
• +6.5 V @ 3.4 A
• - 6.5 V @ 3.4 A
Maximized efficiency and minimized individual component
temperature rise has been achieved with a two stage design consisting of
an input Buck converter feeding a high efficiency Push-Pull output stage.
Overall efficiency exceeds 80% and individual component temperature
rise is minimized by operating both converts at
current, as well as using Schottky rectifier diodes on the output stage.
The power supply is designed to work over the two standard input
voltage ranges 85-264 VAC Universal. The output voltage is adjustable by
±10%.

Overview
Chapter 7
The high efficiency 6804PS(-1) power supply is a self-contained,
plug-in, auto-sensing module that accepts line voltages from 90 to
265 VAC. An external DC power connector allows several frames to be
connected in parallel to back up the supply of power without redundant
supplies. The FR-6804(-1) has space dedicated to an optional second
6804PS(-1) unit when redundant (standby backup) power is required.
The 6804PS(-1) has an internal fuse and an external power switch.
Power supply functioning can be assessed through LED indicators on
the 6804PS(-1) front panel. Illumination of the green LED indicates the
power is on. Illumination of the red LED indicates an over-temperature
condition.
The 6804PS is easily removed and replaced through the front of the
frame after one 6 x 32 screw is removed from the back of the unit. This
power supply doubles the power capability of the frame, from 35 or
40 W to 85 V, provided that it is used with the CF-6801 fan tray which
supplies the forced air cooling for the power supply and the frame during
operation.

GPI Fault Reporting Chapter 7: 6804PS-1 Power Supply Module
GPI Fault Reporting
The GPI (General Purpose Input) is made up of two parts:
• A fault sensing circuit inside each power supply that monitors the
primary circuit and the two output voltages.
• A relay that provides isolation between Leitch equipment and the
GPI output connector at the rear of the frame.
There are three connections provided for GPI reporting:
•Normally closed (NC)
• Normally open (NO)
•Ground
The NC output and ground must be used in order to comply with
SMPTE standards.
The relay has two states for GPI reporting:
• OPEN: An Open output signifies that the GPI relay is activated and
the power supplies in the frame are present and operating correctly.
• CLOSED: A Closed output signifies that the GPI relay has been
deactivated, indicating an internal fault in either of the power
supplies or a loss of power to one or both of the supplies.

the line input range of 90 to 265 VAC. The power supply produces two
identical outputs of opposite polarity with a total output power of 10 W.
The design features the ability to customize the main transformer output
with selection of proper jumpers to obtain the following adjustable
outputs:
•± 6 V
•± 8 V
•± 13V
•± 21 V
Control feedback is taken from the primary side only, giving line
regulation of ± 1% and load regulation of approximately 5% from 20%
load to full load.
6800/7000 Series - Frames and Power Supplies Installation and Operation Manual 35
Page 62
Chapter 8: 7000PS Power Supply Module Output Voltage Selection
Output Voltage Selection
Ouput voltage is controlled by selection of jumpers J1-J4 for positive
voltage, and jumpers J5-J8 for negative output.
Installing jumpers J2 and J4 connects the nominal 7 V ending to the
output rectifier filter circuitry. This allows the power supply to be
adjusted to 6 or 8 V output.
Installing jumpers J1 and J3 connects the 13 volt winding to the output
circuitry and gives a 13 V output.
Installing jumpers J1 and J4 connects the 7 V winding in series with the
13 V winding to the output rectifier and filter circuitry. Two windings in
series gives an output which can be adjusted to 21V.
Installation of jumper J5-J8 give the corresponding negative output
voltages.
