Energy control, Modeling light, Sync signaling

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 sectionTechnical data.

Most gas generators with an output of 800W 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.

10WARNING:

Never use ordinary household extension cords to elongate the power cable.They may overheat.Always unwind cord reel extension winders fully before useContact. your Profoto dealer for proper equipment.

Due to the two stage SMPS technology, the D1 could make a hearable sound during the recharge cycle.This is fully normal and could be seen as the sign ofwerpo being charged into the unit.

Energy control

The current energy level of the flash light is shown in the Display [1] in f-stop scaleThe. maximal energy (100%) is shown as 10.

The Setting Knob [7] is used to adjust the energ y 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 ProfotoAir radio system.

•The 5 meter sync cable can without restrictions be elongated with a sync extension

cable. The Profoto sync interconnection cord or so called “hard wiring” may be used.
