Functionality
LiFe Batteries
Profoto uses the most advanced and reliable rechargeable batteries: Lithium Ion Iron
Phosphate (LiFePO4), short – LiFe batteries. These batteries include sophisticated
electronics: A special constructed BMS board (Battery Monitoring System) controls and
adjusts their output to assure an optimal performance.
LiFe cells offer a very high capacity, are lightweight, stand high loads and are very safe and
reliable. The integrated electronics also protect the LiFe battery against deep-discharge
and overheating. On top they have a much longer life-time than lead acid batteries and can
be used in a wider temperature range. Because of their special construction it is possible to
apply the same chargers for LiFe and Pb (lead acid) batteries; this simplifies the combined
use of new and old battery generators and allows owners of previous Profoto battery
generators to update their packs with the new LiFe batteries.
The Pro-B3 generator is equipped with a LiFe battery. The generator cannot be used
without a battery in place.
The battery can be charged through the mains outlet using a Profoto Charger 2A or from the
car cigarette lighter using the Profoto Charger UPA. The battery can be charged separately
or with the battery in place in the generator. The generator can be used during charging.
The battery can be charged from any charge level, but should not be charged for longer
time than necessary. For a long battery life, the battery shall be fully recharged prior to
storage.
Defective batteries shall be returned to the dealer for recycling. For details about the
battery, see section Technical data.
Power on/off
The generator is normally turned on manually, by pressing the On/Off Button [13]. If a
sync signal from a camera is received via one of the Sync Sockets [7], the generator
automatically turns on.
The generator automatically turns off after 30 minutes when not in use. For manual power
off, press the On/Off Button [13] for more than three seconds.
Battery Indicator
The Battery Indicator [4] indicates the battery level. The indicator is updated when a flash
is triggered. At start up, all four lamps can lit up, and a flash should be triggered to get an
updated battery indication. Because of the discharge characteristics of the LiFe battery,
the Battery Indicator [4] will remain on max until it suddenly drops, when there is battery
capacity for just a few more flashes.

Pro-B3 1200 AirS

www.profoto.com
Energy control
The energy output is regulated over eight f-stops.
The energy can partly be adjusted with the Energy Control [20] in 1/2 f-stop increments,
from 1/1 down to 1/16 of the total energy (equivalent to five f-stops). Fine adjustment of
the energy is made with the Fine Energy Control [19] in 1/10 f-stop increments.
The energy is also partly adjusted with the SYM/ASYM Switch [2] and through the use of
one or two lamp heads:
One lamp head:
• If the lamp head is connected to Lamp Head Socket A [1], the total of the selected
energy is obtained if the SYM/ASYM Switch [2] is set to position “A1/1 (1/2)” and
half of the energy if the SYM/ASYM Switch [2] is set to position “A1/2”.
• If the lamp head is connected to Lamp Head Socket B [3], half of the selected energy
is obtained if the SYM/ASYM Switch [2] is set to position “B1/2”and a quarter of the
energy if the SYM/ASYM Switch [2] is set to position “B1/4”.
Two lamp heads:
• The selected energy can either be distributed evenly through the two lamp heads,
by setting the SYM/ASYM Switch [2] to position “B1/2, A1/1 (1/2)”.
• Alternatively, twice as much energy (equivalent to one f-stop ratio) will be output
through lamp head A, by setting the SYM/ASYM Switch [2] to position “B1/4, A1/2”.
Since the generator has auto dump functionality, there is no need to trigger a flash to
discharge the generator when the energy level is lowered.
Recycling time
The recycling time is controlled with the Recycling Button [11]. When the Recycling Button
[11] is released, the generator will recycle at normal speed; when the button is pushed
down, the recycling will be faster.
The recycling time also depends on the energy level setting. When a short recycling time
is required, the energy level shall be set as low as possible. For details on recycling times,
see section Technical data.
Modeling light
The modeling light is constant and does not vary with the selected energy level. The
maximum modeling light is 250 W. The modeling light is automatically dimmed down to
max 250 W if a 500W model lamp is used. Since the efficiency (output) is higher when using
a 100 or 250 W lamp head, we recommend using max 250 W heads.

Pro-B3 1200 AirS
11
www.profoto.com
The Modeling Light Button [12] is used to turn on/off the modeling light.
The Modeling Light Control [14] is used to select time controlled or continuous modeling
light:
• TIME: To save the battery, the modeling light is automatically turned off after 10
seconds or when a flash is triggered. By pressing the Modeling Light Button [12] two
or three consecutive times, the modeling light will stay on for 30 and 60 seconds
respectively. For every period of 20 seconds that the modeling light is turned on, the
battery capacity decreases by the equivalent of two flashes at full energy.
• CONT: The modeling light is continuously on, but the modeling lamp will
automatically dim down during recycling or when the energy output is changed. In
this position, the battery is drained within 20-60 minutes depending on the lamp
head used (100 or 250 W) and the number of flashes triggered.
If the former Pro-7 heads are used on the Pro-B3 we recommend to turn off the model light.
Sync signaling
The Pro-B3 generator can be synchronized with the camera in different ways; via cable,
photocell or via radio.
• The two Sync Sockets [7] allow the camera and a flash meter to be connected
simultaneously. The 5 meter sync cable can without restrictions be extended with
sync extension cords. Further sync connections can be made with the Profoto sync
interconnection cable or by so called “hard wiring”. A slave signal from the Photocell
[6] can be forwarded through this cable to another flash generator.
• The Photocell [6] will sense a flash release as well as signals from most IR sync
transmitters. The Photocell is enabled when the Slave Button [8] is pushed down.
The Photocell can also, via cable, trigger off an additional generator.
• The Profoto Air radio system is integrated in all Pro-B3 generators, meaning that the
generators can be synchronized via a Profoto Air Remote or Profoto Air Sync device.
• The Pro-B3 AirS 344MHz and the Pro-B3 AirS 433MHz generators have an
integrated radio receiver for synchronization via the Pocket Wizard device.
Always check the manuals of the camera and synchro device about the shortest possible
sync times before taking pictures!
Radio operation
The Profoto Air radio receiver is turned on/off with the Radio On/Off Button [17].
The Pocket Wizard radio receiver is always in operation while the generator is powered
on. When the Pocket Wizard system is used, it is recommended to turn off the Profoto Air
system.

Pro-B3 1200 AirS
12
www.profoto.com
For best radio operation (Profoto Air and Pocket Wizard), do the following:
• Keep power, sync and lamp head cords away from the antenna.
• Maintain line of sight between the transmitter (Profoto Air Sync/Remote or Pocket
Wizard) and the generator whenever possible.
• When hiding the generator from view, try to not hide it behind or against metal or
water filled objects as this affects radio range.
• For Pocket Wizard: keep the transmitter’s antenna parallel with the generator
antenna.
Channel selection – Profoto Air
Channel selection is used to select one of eight specific frequencies in the 2.4 GHz band.
The frequencies are evenly spread over the entire frequency band, to optimize reliable
functionality. The large number of radio channels makes it possible to select a channel
that is not interfered by other photographers using Profoto Air, or by WLAN and Bluetooth
devices and other radio equipment operating on the same widely used 2.4 GHz frequency
band.
Channel selection on the generator is made with the Channel Button [16]. The Channel
Indicator [18] corresponding to the selected radio channel (1-8) is illuminated.
Channel and Zone selection – Pocket Wizard
The Pocket Wizard radio receiver has a learning function, which means that during 30
seconds from power on it will try to detect a trigger signal on any of the 32 channels.
If a trigger signal is detected, the radio receiver will lock to that channel. If no trigger is
detected, the radio receiver will use the previously used channel. Actual photo shooting
with radio should not be performed during the 30 second learn period, since the result may
be unpredictable due to the channel learning process.
The Pocket Wizard radio receiver can also learn multiple zones on the Quad-Triggering
channels, 17 through 32. This provides the photographer with the convenience of
activating or deactivating the flash unit(s) wirelessly in four separately controllable zones
(ABCD), without leaving the camera position.
Example: The teaching Transmitter is set to channel 17 with zones A, B, and C selected.
If the generator is taught this combination it will trigger from any Transmitter set to
channel 17 with zones A, B, or C selected. It will not trigger if only zone D is selected on the
Transmitter. It will trigger if zones A and D are selected.
Audible and visible signals
The Ready Lamp [9] is illuminated when the generator is fully charged (100%) and ready
to flash. When the energy output is changed, the Ready Lamp [9] and the modeling lamp
will be turned off, indicating that dumping or charging of the energy is in progress.

Pro-B3 1200 AirS
13
www.profoto.com
When the recycling of the generator is completed, there will be a short audible “beep”
sound. If a flash is triggered before recycling or auto dumping (when the energy level has
been lowered) is completed, there will be a long “beep”, indicating an underexposed or
overexposed frame. Before the generator automatically turns of (after 30 minutes when
not in use), there will a number of short “beeps”. The audible sounds are enabled when the
Sound Button [10] is pushed down, and disabled when the button is released.
Test function
The Test Button [9] is used to test that all light settings are correct and that the functionally
is as expected. When the Test Button [9] is pressed, the generator will flash and the Ready
Lamp [9] will be turned off. When the recycle of the generator is completed, the Ready
Lamp [9] will be turned on again.
Flash before ready
The “Flash before ready” function makes it possible to flash before the recycling or auto
dumping of the generator is fully completed. When a flash is released before the generator
is 100% ready, there will be a long “beep”, indicating an incorrectly exposed frame.
Naturally the flash light may not correspond fully to the set value. The incorrect exposure
of the frame may be so small that it makes no significant difference and the frame may still
be usable if the catch of the moment was perfect.
Safety functions
If the generator overheats, the recycling will slow down or stop. After a while, when the
temperature has decreased sufficiently, the generator will start recycling as normal. The
generator automatically shuts down if the battery level is too low, to protect it from deep
battery discharge. There are three fuses on the battery cassette; one is for the charging
circuits and two for the battery. Furthermore the lamp connectors are short-circuiting
proof.
Reliability testing – the R-test
The Profoto R-test guarantees that all products leaving the factory meet the very high
standards required for professional equipment by professional photographers. After the
test, the equipment is examined to verify that all parts have kept a normal operating
temperature and are not malfunctioning in any way. All Profoto products are subject to the
R-test prior to shipping.
Color temperature
Since the color temperature is constant and reliable, the Pro-B3 is perfectly suited for
digital photography. By turning the Energy Control [20] from MAX to -4 and the Fine Energy
Control [19] from MAX to -1, the color temperature is changed nominally -250 K. Flash
to Flash color precision, ±50 °K. Optional glass covers are available for further color
temperature adjustments.

Pro-B3 1200 AirS

Flash duration
The full power short flash duration has more advantages than freezing a moving object, for
example to cut out exposure influence from indoor ambient light as well as direct sunlight.
Consult the camera manual for information about the shortest flash sync time.
The shortest flash duration (1/7400s) is achieved with both the Energy Control [20] and
the Fine Energy Control [19] set to MAX, the SYM/ASYM Switch [2] set to “B1/4, A1/2” and
with only one lamp head connected to Lamp Head Socket B [3].
