The power supply is a custom power supply capable of supplying 1000 Watts of
secondary power to the overall mainframe with an input power of up to
1450 Watts operating at it’s minimum 70% efficiency. The power supply
incorporates a continuous AC source operating in the range of 90 to 250 VAC
(from 45 Hz to 66 Hz) and 100 to 132 VAC (from 360 Hz to 440 Hz). This
covers virtually all international power combinations. The power supply also
supports automatic power factor correction and over-voltage, current, and
thermal protection mechanisms.
