400 Watt Power Supply
The 400 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 8 amps maximum for the 115 VAC range and
4 amps for the 230 VAC range. The power supply has a minimum efficiency of 70 percent at
maximum output load. The power supply is enclosed in a case that includes a fan for additional
airflow through the system.
The power supply has the following DC output specifications.
