CHAPTER 3: Drive Specifications SDLT 220 and SDLT 320 Product Manual

3-10 March 2004 81-85002-01

3.2.3 Current and Power Requirements

Table 3-11 on page 3-11 lists the current and power requirements for both versions

of the tape system (internal and tabletop). The tabletop version requires AC power.

The highest current (and power) is drawn during the native write modes and

backward-read compatibility (BRC) read modes, so they are outlined in

Table 3-11. Standby is measured with the tape loaded and tensioned or

untensioned, and Idle is measured with power on with no tape loaded. (The

power drawn in these two modes is similar enough that they are listed together.)

Power-up current surges are less than those encountered during motor

accelerations, and so are not listed separately.

NOTE: In Table 3-11, the current and DC power values are

relevant to the internal drive, while the AC power values

are relevant to the tabletop drive.
