The Profoto ProTwin 4800 ws flash /strobe head when used with a single pack produces a shorter flash duration. When using two 2400 ws power packs, it achieves faster recycling and a maximum of 4800ws with one flash head.

Caution: Both connectors must be connected or there will be a risk of overheating. Cable must not be used when it is coiled up. Covering the cable with a rug or rag can trap heat and overheat the cord.
Attention: Maximum continuous flash load, 48000 ws/minute ( 10 x 4800ws, 20 x 2400 ws flashes )
