Power Pak
The Brooks Automation Power Pak is a battery back-up power source for the Mag-
naTran 7 robot. This compact power fault manager mounts directly on the side of the
robot drive and connects between the robot’s DC power supply and the MagnaTran
7. One cable carries all DC power, ground and interface signals to the MagnaTran 7.
The Brooks Automation Power Pak provides a safe recovery of the robot arms within
two seconds after power loss. The Power Pak also provides immediate removal of
power to the robot after EMO actuation. When the primary power is returned, the
robot will power up in its normal condition.
The Power Pak has a 2.5 year life and a built-in charging circuit.
Power Supply
The robot’s power supply pr24 VDC ±10% at a current rating of approxi-
mately 20 amps.
A power converter in the robot delivers all internally required operating voltages
throughout the control system. The actual current drawn by the robot will vary and
depends upon the specific function the robot is performing.
