Power Specifications
This section lists the power specifications for the tape drive.
Voltages
The tape drive operates from standard +5 VDC and +12 VDC supply
voltages, as specified in Table 6-7. All specified voltages are DC; no
external AC power is used by the tape drive. The tape drive does not
provide any overvoltage or overcurrent protection.

a
The ripple voltage is included in the total voltage tolerance.
b
Nominal current occurs during streaming write or read operation.
c
The SLDS card is the single-ended card; the SLDD card is the differential card.
d
The peak current occurs during load, unload, or at the start of search or rewind
operations, and lasts for less than 1.5 seconds.
Safety agency certification requires that the supplied voltages be from
a Safety Extra-Low Voltage source (per IEC 950).
