The PowerST4 receiver enables remote power control of Elinchrom RX flash units using PocketWizard ControlTL technology.

With a MiniTT1 transmitter or a FlexTT5 receiver on your camera and a PowerST4 connected to your Elinchrom RX flash, you can now adjust the flash power settings directly from the camera's location. By adding the AC3 ZoneController, you can control three different light zones in 1/3 stop increments over a range of six stops.

Utilize PocketWizard's unique features like HyperSync or optimized curtain sync for maximum control over your lighting.
