HYSICAL ELECTRICAL SPECIFICATIONS
This section provides information relating to the physical and electrical characteristics of the drive.
6.1 AC
POWER REQUIREMENTS
None.
6.2 DC
POWER REQUIREMENTS
The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector.
Notes are shown following the last power requirements table.
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion
of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V
supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on
the 12V supply.
