MID49 Power Distribution Box DB-4 for Canon C80/C70 (V-Mount, Rod Mounted)

Overview

Power Distribution Box DB-4 (Canon C70, V-Mount) attaches to 15mm LW rods with a hinge pivot and provides intelligent power distribution with D-Taps, 5V USB-C PD, 3pin Fischers, and 2pin LEMO compatible connectors. Removable REMOTE LANC cable enables remote start/stop capability using 3pin Fischer devices.

The DB-4 is also compatible with Canon C80.

Hot-swap between on-board battery and 4pin XLR DC INPUT without losing camera or accessory power. When both sources are connected, the DC INPUT takes priority down to 12.5V at which point, the DB-4 will switch to an onboard battery.

The shoe mount design allows Canon’s BP-A30N battery to be installed in the camera to function as an emergency backup. To swap the internal battery, swing the DB-4 up and release the battery. Note that the DB-4 provides 19.5V to the camera so that the camera will default to the DC input.

The DB-4 can also be separated from its hinge mount, revealing a 15mm rod clamp with an internal friction sleeve.

With the SMART FUSE design, camera power is monitored, and the remaining power budget is allocated to accessories. For example, the C70 uses approximately 1.0A at 14V so when using a 10A capable battery, the remaining 9.0A is allocated for accessory use. If an accessory configuration exceeds the 9.0A limit, accessory power is cut off, leaving the camera powered. The “SMART FUSE” LED will illuminate, showing the error, and once the configuration has been adjusted to lower than 9.0A, the RESET button can be pressed, and power will be re-enabled to accessory outputs.

In the event of a complete short circuit, the system will immediately shut down and can only be turned back on once the short circuit has been removed.
