Connecting 24 VDC Power to Robot
Adept Cobra i600/i800 Robot User’s Guide, Rev E 47
4.6 Connecting 24 VDC Power to Robot
Specifications for 24 VDC Power
The power requirements for the user-supplied power supply will vary depending on the
configuration of the robot and connected devices. Adept recommends a 24 V, 6 A power
supply to allow for startup current draw and load from connected user devices, such as
solenoids and digital I/O loads. If multiple robots are to be sourced from a common 24 V
power supply, increase the supply capacity by 3 A for each additional robot.

User-supplied 24 V power supply must incorporate overload protection to limit peak
power to less than 300 W,
or 8 A in-line fuse protection must be added to the 24 V
power source. (In case of multiple robots on a common 24 V supply, each robot must
be fused individually.)
