ALEXA Dedicated V-mount Plate
Aluminum CNC unibody housing
The V-mount plate KA-A20S is designed for ARRI ALEXA LF, ALEXA 65, ALEXA SXT etc, with Aluminum CNC unibody housing, perfectly match with ALEXA cameras, robust and reliable.


High Voltage to ALEXA
Match with PB-H290S to output 22-33.6V
SWIT Bi-voltage battery PB-H290S can recognize the KA-A20S plate and auto switch on 22-33.6V, to power Alexa LF/65/SXT etc.
Use other batteries, the KA-A20S plate will not change voltage, and directly power the camera.


High Load Reliable Pins
Battery Contact Pins:
Unique lantern type pins, wider contact surface,
support Max 16A current without overheating;
Camera Contact Pins:
Copper rod direct conducting (instead of spring
conducting), and the strong spring makes fully
contact with camera pins, ensure 10A reliable
current and prevent overheat.


Multi DC Sockets
D-tap / LEMO / USB
KA-A20S plate provides 2x D-tap, 1x 2-pin LEMO and
1x 5V/2A USB output.
Under 22-33.6V power, the D-tap and LEMO outputs
constant 16V, Max 6A;
Under 11-16.8V power, the D-tap and LEMO outputs
original battery power.

We provide a 1-year conditional warranty, and the following damages/issues are not covered under warranty:
(1) Any damage or malfunction caused by use, maintenance, or installation not in accordance with the User Manual's instructions, including improper battery insertion or removal, incorrect polarity connection, exposure to moisture or conductive debris, or disassembly/repair without authorization of SWIT.
(2) Any damage caused by using third-party batteries, power sources, or accessories that do not comply with the recommended electrical specifications (e.g., voltage, current, or contact pin configuration), including but not limited to electrode overheating, melting, arcing, or short circuits resulting from incompatible battery design or poor battery quality.
(3) Any damage caused by irresistible factors (such as earthquake, fire, lightning, flood, etc.) or human factors including dropping the plate, impact damage, forced battery removal at incorrect angles, or insertion of damaged or deformed batteries.
(4) Any damage or malfunction not caused by the product's design, workmanship, or manufacturing quality — including normal wear and tear of spring-loaded electrodes, contact pins, locking mechanisms, or surface finish scratching.
(5) Electrode breakage, bending, or deformation resulting from violent use, excessive force during battery attachment or detachment, or improper alignment of the battery onto the plate is specifically excluded from warranty coverage. This includes snapped, crushed, or pushed-in contact pins caused by user mishandling.
(6) Electrical or thermal damage (including melted plastic around electrodes, burnt contacts, or discoloration from heat) that is determined to be caused by a third-party battery's internal short circuit, over-current draw, overheating, or defective connector design shall not be covered under this warranty. Such conditions are the responsibility of the battery manufacturer.
