Used Elinchrom 115VAC Digital 2400 RX Power Pack

The 115 VAC Elinchrom Digital 2400 RX Power Pack is a high performance 2400W/s strobe generator with power variable over 6 stops in 1/10 stop increments, short flash duration and a full power recycling time of 3.8. The pack offers numerous triggering methods with separate purchase of optional EL Skyport Transceivers and Mac and PC interfaces, as well as a built-in optical/IR slave and sync outlet.

There's even an iPad/iPhone control app available for use with an optional Wi-Fi module. Power from the two flash outlets can be distributed symmetrically or asymmetrically by using two flash heads with different power draw such as the "A" and "S" heads resulting in a 75/25% split instead of 5-/50%.
