in the unit.Do not connect this equipment to flash equipment from other brands.Do not use flash heads
without supplied protective glass covers or protective grids. Glass covers shall be changed if it has
become visibly damaged to such an extent that their effectiveness is impaired, for example by cracks
or deep scratches. Lamps shall be changed if they are damaged or thermally deformed.When placing
a lamp into the holder ensure not to touch the bulb with bare hands. Equipment must only be serviced,
modified or repaired by authorized and competent service personnel! Warning - The terminals marked
with the flash symbol are hazardous live.
WARNING – Electrical Shock – High Voltage!
Mains powered generator shall always be connected to a mains socket outlet with a protective earthing
connection! Only use Profoto extension cables! Do not open or disassemble generator or lamp head!
Equipment operates with high voltage. Generator capacitors are electrically charged for a considerable
time after being turned off. Do not touch modeling lamp or flash tube when mounting umbrella metal

Caution – Burn Hazard – Hot Parts!
Do not touch hot parts with bare fingers! Modeling lamps, flash tubes and certain metal parts emit
strong heat when used! Do not point modeling lamps or flash tubes too close to persons.All lamps may
on rare occasions explode and throw out hot particles! Make sure that rated voltage for modeling lamp
corresponds with technical data of user guide regarding power supply!

System description
Profoto’s 40 years of experience in developing state-of-the-art flash units is built into the
design of the D1 units.The D1 family fully complies with the demand for durable, tough,
fast and consistent flash units that professional photographers of today require.
The D1 unit is available in 250, 500 and 1000 Ws versions, all with integrated Profoto
Air functionality.The 250 and 500Ws versions are also available without ProfotoAir.The
unit is fully digital, to ensure a consistency in flash-to-flash color temperature and flash
energy.The dual mode SMPS (Switch Mode Power Supply) charging technology ensures
the flash-to-flash precision.The 7 f-stop power range gives all the power the demanding
photographer needs for creative freedom,to shoot with high speed and full open lens.
The built-in reflector gives you full control,minimal stray light and maximal light output.
It is designed for use with soft boxes and umbrellas and for use with or without additional
reflectors.
Short flash duration gives images a crisp feel and the fast recycling time means that you
never have to wait for the flash.You will always get the image quality you want.All this in
a package that offers 1/10 f-stop control,giving you the confidence that the images will
be exactly as you want them.
As a professional photographer, you have your own special style and needs. Profoto’s
extensiveLightShapingToolssystemfitsperfectlywiththe D1,enablingyoutoshape the
light your own way.
ProfotoAir
Profoto Air is a system for convenient remote control of flash generators. The Profoto
Air system is operating on one of eight selectable radio channels on the 2.4 GHz radio
frequency band,for world wide use.
All Profoto flash generators with Profoto Air inside can be controlled via the Profoto Air
system. Products with integrated Profoto Air functionality are marked with the Profoto
Air symbol.

Functionality
Power supply
The D1 unit can be connected to 100-120 VAC or 200-240 VAC, 50-60 Hz. The unit
automaticallysensesandadaptstothesuppliedvoltageandfrequency.Thepowersupply
fuses must not be smaller than specified in the section Technical data.
Most gas generators with an output of 800 W constant load, or more, can power the D1
unit.Thanks to the two stage SMPS (Switch Mode Power Supply) technology, no ProGas
unit is needed.
Warning:
Neveruseordinaryhouseholdextensioncordstoelongatethepowercable.Theymayoverheat.Alwaysunwindcord
reelextensionwinders fully beforeuse.Contact your Profotodealerfor proper equipment.
Due to the two stage SMPS technology, the D1 could make a audible sound during the
recharge cycle.This is fully normal and could be seen as the sign of power being charged
into the unit.
Energy control
The current energy level of the flash light is shown in the Display [1] in f-stop scale.The
maximal energy (100%) is shown as 10.
The Setting Knob [7] is used to adjust the energy level, in 1/10 f-stop or 1 f-stop
increments.
Modelinglight
The Model Button [10a] is used to select one of three modeling light alternatives:

Adaptive thermal control
The D1 unit is equipped with an adaptive thermal control system. If there is risk for
over heating of the unit, caused by either heavy use or abnormal external influence, the
thermalcontrolsystemwillautomaticallyprotecttheunitfromdamage.Amicroprocessor
supervises and controlstheunit,based on inputfromfour thermalsensors.Ifthesensors
report an increase in temperature, the microprocessor automatically takes measures
to protect the unit.The first measure is to increase the fan speed. If the fan at full speed
cannot bring the temperature down, the modeling light will automatically be turned off
during recharging.Next step is to turn off the modeling light completely and at the same
time slow down the recharging. Eventually the recharging will stop completely. After a
while,whenthe temperature hasdecreased sufficiently,theunitwill startrecharging at a
normalpace.Thisautomaticprotectionwillonlyinterfereunderextremeconditions,such
as when the air vents are blocked.
Depending on version,the D1 unit is designed to withstand up to 1000 full power flashes
duringonehour.However,itis not recommended to run harder thannecessary due to the
lifetime of the flash tube.
Ifadefective flashhead–forexamplewithabrokenormisfiringflashtube–isused,after
releasing the flash a long beep signal will indicate malfunction/underexposure.
Notice:
Theairventsoftheunitmust never be blocked or covered in any way.Never store yourflashequipmentinacaron
