SWIT KA-B30B 200W B-Mount Hot-Swap Battery Plate

The SWIT KA-B30B B-mount hot-swap battery plate keeps compatible cinema cameras operating while crews replace a depleted battery. Its integrated 32Wh battery supplies regulated 28V power at loads up to 200W, providing at least 120 seconds to install a charged B-mount battery without shutting down the camera.

Designed for professional cinema productions, the plate supports ARRI ALEXA 35, ARRI ALEXA 265, Blackmagic URSA Cine, and other equipment fitted with a high-voltage B-mount interface. A built-in LCD begins a 120-second countdown when the external battery is removed, giving camera teams a clear view of the remaining changeover time during live productions and demanding location shoots.

The KA-B30B also functions as a centralized power hub for camera-mounted accessories. Two regulated D-Tap outputs, a regulated 2-pin LEMO output, and a USB-A connection power monitors, wireless transmitters, focus systems, and mobile devices. An 8-pin LEMO input supports external power-station operation, while the CNC-machined aluminum housing and multiple circuit protections provide durability for professional production environments.
