Exceptionally compact, the ELB 400 Quadra Power Pack from Elinchrom provides a portable flash option for users of Quadra heads. Its size makes it easy to carry around, either on a belt or using the separately available shoulder strap. It boasts a 424Ws output and 6.9-stop power range as well as asymmetrical 2:1 outlets for two flash heads. Another advantage of this system is the integrated EL-Skyport radio receiver, which allows users to pick up an optional remote to gain remote triggering and high-sync support. Additionally, it can produce up to 350 full-power flashes from the separately available battery pack.
In terms of speed, the ELB 400 boasts recycle times of 0.17-3.5 seconds and flash durations of 1/1200-1/2800 when at 100% power. The pack also features an OLED display for clearly viewing settings as well as a 3.5mm sync port for a conventional wired setup. The ELB 400 can even have the modeling light set up with programmable timers in addition to the on, off, and continuous modes. And, for those on the move, the pack only weighs 4.4 lb with the separately available battery.
