FIGURE E.3 - INPUT POWER & DISTRIBUTION
INPUT POWER & DISTRIBUTION
The single phase input power (115-240VAC) is applied
through a terminal strip and a momentary switch to four
discreet components. They are the computer assembly
(CPU), the 5VDC supply, the 12VDC supply and the
monitor. These components rectify the AC input and
regulate the resultant DC voltage to operate the inter-
nal electronics of the VRTEX TM 360.
When the CPU has been energized the momentary
“ON” switch is bypassed by the interlock relay. The
5VDC created by the CPU is applied, via a USB cable
to the interlock relay. The independent 5VDC supply
provides power to the Polhemus Interface Module, and
the FMD Control Unit. The other independent 12VDC
supply provides power to the VGA Splitter and via the
Relay PC Board to the Motor Control Board.
