The RP400 400W/s power pack is the smallest made by Dynalite. This Road series pack is powerful and versatile enough to handle a wide variety assignments. The pack has 3 head outlets and breaks down its output symmetrically or asymmetrically over a 6 stop range with short flash durations at a super fast 1.0 seconds recycling time at full power.
A variator knob allows fine tuned exposure adjustments over 2 stops in 2/10 stop increments. Triggering options include sync cord (provided) or optical slave. The RP400 is compatible with most optional radio remote systems such as PocketWizard with the proper cable. The 400w/s power pack when compared to the previous 500 w/s models are 1" shorter, 1/2 lb. lighter, and the recycling time is 60% faster! These packs are perfect for photographers who frequently are bringing their equipment on location.
