3.3 10 *
The 5 and 3.3 VDC outputs "power-share." Since the maximum power
output of the 12 VDC supply is 30 W, the remaining 40 W is shared between
the 3.3 and 5 VDC supplies. If no load in 3.3 V and 12 V limited to 0.6 A,
then 5 V can deliver 12 A.
Input Voltage: 100 - 240 VAC, 50/60 Hz
Maximum Input Current: 1.5 A
