Functionality
Power supply
The D1 unit can be connected to 100-120 VAC or 200-240 VAC, 50-60 Hz. The unit
automatically senses and adapts to the supplied voltage and frequency. The power supply
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:
Never use ordinary household extension cords to elongate the power cable. They may overheat. Always unwind cord
reel extension winders fully before use. Contact your Profoto dealer for 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.
Modeling light
The Model Button [10a] is used to select one of three modeling light alternatives:
• PROP:Themodelinglightintensityisautomaticallyadjustedtocorrespondtothe
energy level of the flash light.
• FREE:Themodelinglightintensityismanuallyset,freefromanyconnectiontothe
energy level of the flash light.
• OFF:Nomodelinglight.
The Model Set Button [11], in combination with the Setting Knob [7], is used to change the
level of the free modeling light.
Sync signaling
The D1 unit can be synchronized in different ways; via cable, via infrared (IR) light or via
the Profoto Air radio system.

used.
