The new and improved SHAPE 19.5V output D-Tap power cable for Sony FX9 / FX6 regulates the voltage from a D-Tap source to the proper 19.5V required to power an FX9 / FX6 cameras. This new version includes a reverse polarity protection system which is integrated within the casing to prevent electrical issues if the D-tap connector is plugged backwards. If plugged backwards, the system will store the negative energy within the casing and block it from going to the camera and damage it. The cable includes an aluminum heat dissipating casing with two warning lights. A green light to confirm the right amount of power is passing through to power the camera. And a red light to warn not enough power is passing through. The cable allows you to power your camera using any V-mount or Gold mount battery with a D-Tap plug. The cable has a total end-to-end length of 15″ / 38 cm.
