CHAPTER 3: Electrical Specifications
3.2 Power Supply Tolerances
One of the functions of the power supply is to transform the AC power to DC, and
to step the voltage down from 115/220 Vac to 5 Vdc and 12 Vdc.
3.2.1 Voltage Tolerances
Voltage tolerances are:
•
5 Vdc
±
5%
•
12 Vdc
±
5%
3.2.2 DC Voltage Monitoring
The tape drive will monitor the two input voltages and take protective measures
when the voltages fall or rise beyond the below specified ranges:
3.2.3 Power Cycle Time
Test results show that an SDLT drive is able to power up and perform reliably with
up to 11 seconds of delay time between the 5V and the 12V source. The drive is
also able to power up and perform successfully with rise times of up to 11 seconds
on either the 5V and the 12V supply (while the other is stable).
