Power Supply

The 670-watt autosensing power supply has a voltage range of 90 to 264 Volts root-
mean-square (VRMS) with a frequency range of 47 to 63 Hz. The maximum input
current is 12 amps at 100 volts.
The power supply output voltages are listed in the following table. The power
supply continues to regulate all outputs for 10 milliseconds after AC power is
removed.
