Power Specifications
The following table lists the power specifications for the internal DAT 72 and DDS-4
drives.
Total power consumption for the DAT 72 is as follows:
8.7 watts typical, 10.0 watts max
20.0 watts max (instantaneous peak)
Note:
When measured over a 20-msec period, the maximum surge power is 14.0
watts.
Total power consumption for the DDS-4 (including both the +5V and +12V power
supplies) is as follows:
9.0 watts typical, 10.0 watts max
Note:
Surge power and current are measured over a 20-msec period.
The following table lists pin assignments of the power connector for the internal DDS.
The external drives have a built-in power supply that senses the incoming voltage
and automatically adapts to voltages within the range of 100 to 240 volts, 50 to 60
Hz. The following table lists the power specifications of the power supply.
Note:
The drive employs a power-sensing circuit that automatically detects a loss
of supply voltage from the host. Temporary loss of supply voltage, or voltage
spikes, might result in the drive electronics being reset to their initialized
state, but shall under no circumstances result in a loss of recorded data.
