Power Supply and Cables
Different power supplies are used in the different system configurations. The power supply in each
system is field replaceable. See Chapter 9, “Servicing System Components,” for details on
replacing the power supply.
300 Watt Power Supply
The 300 Watt power supply has a manual switch for selecting either 115 VAC (90-132 VAC)
range or 230 VAC (180-264 VAC) range for domestic or international locations. The input
frequency is 47-63 Hz, single phase. Input current is 7 amps maximum for the 115 VAC range and
3.5 amps for the 230 VAC range. The power supply has a typical efficiency of 70 percent at
maximum output load. The power supply is enclosed in a case that includes a fan for additional
airflow.
