Protective device against damaging high voltage. Must be used when powering Pro-7, Pro-6, ProPack, Acute/D4or ComPact with a 230 V petrol electric generator set.
Most gas generators with an output of 3000 W or more can always power Pro-7 or D4 generators. Please note that on 230 V markets a ProGas unit between the gas generator and the Profoto generator is needed in order not to damage the units.
For the Acute generator a min 2000 W true output gas generator is needed per flash unit and it can also power 2 ComPact flashes.
