Swit KA-R30B B-mount Hotswap Plate for MINI / MINI LF

Professional B-mount Hot-swap Solution

The Swit KA-R30B is a dedicated B-mount hot-swap plate designed specifically for ARRI Alexa MINI and MINI LF cameras. It provides a reliable 28.8V (22-33.6V) power supply via an 8-pin DC-IN connection. By utilizing an internal battery, this plate ensures your camera remains powered during battery changes, eliminating downtime on set.

Seamless ARRI Integration

The KA-R30B is engineered to integrate perfectly with the original ARRI MINI / MINI LF support system. It connects via the RAB-1 Clamp 2 (K2.0023406). Please note that the KA-R30B does not include the K2.0023406 clamp. For older setups, a 15mm rod adapter is included in the package to ensure compatibility with legacy 15mm rig systems.

High-Capacity Internal Cells

Equipped with 32Wh/3Ah internal battery cells, the plate supports a constant high load of 200W. Even after 1000 cycles, the KA-R30B guarantees at least 120 seconds of run time, providing ample time to swap your main B-mount battery without interrupting the recording or shutting down the camera.

Intelligent Countdown Display

An integrated LCD screen provides a clear 120-second countdown timer when the main battery is removed. Once a fresh battery is attached, the internal cells are automatically recharged, and the countdown resets to 120 seconds for the next swap, ensuring the system is always ready for the next transition.
