The Swit KA-A20S plate V-mount for ALEXA LF / 65 / SXT is able to recognize the KA-A20S plate and automatically switch to 22-33.6 V, to power Alexa LF/65/SXT. If other batteries are used, the KA-A20S plate does not change voltage and powers the camera directly. Battery contact pins: Unique lantern pins, wider contact surface, support a maximum current of 16A without overheating; Camera contact pins: Direct-conducting (rather than spring-conducting) copper rod, and the strong spring makes full contact with the camera pins, providing a reliable current of 10A and preventing overheating. The KA-A20S plate provides 2x D-tap, 1x 2-pin LEMO and 1x 5V/2A USB output. With a power supply of 22-33.6 V, the D-tap and LEMO outputs are constant at 16 V, max 6 A, while with a power supply of 11-16.8 V, the D-tap and LEMO outputs provide the original battery power.
