Power Configurations
Required for redundant robotics and redundant electronics support
■
2N+1 power configuration
Offers both AC and DC power redundancy with additional DC redundancy
■
Consists of two PDUs (per Base module or DEM) for AC redundancy, with
■
additional DC power supplies for each PDU
Provides N+1 DC power redundancy for each PDU (except the second PDU only
■
has N DC power supply redundancy for the robot)
Requires two separate AC input sources per Base module or DEM
■
Supports redundant robotics and redundant electronics
■

DC Power Supplies

There are two types of DC power supplies:
Load sharing 1200W DC — used for the robotics unit and tape drives
■
200W cPCI — used for the electronics control module
