SWIT KA-B30B B-Mount Hotswap Plate

The KA-B30B sits between a B-Mount camera and its main battery, holding a 32Wh internal cell that bridges the gap when the main pack is swapped mid-take. With a battery attached it passes through 22 to 33.6V at up to 200W; pull the battery and the internal cell alone still delivers a regulated 28V at 200W for a brief handoff.

Beyond the camera mount itself, it breaks power out to two 14V D-Tap sockets and a 2-pin LEMO output at 70W each, plus a 5V USB-A port for accessories, so a monitor or wireless link can run off the same plate as the camera.
