Voyager Platform Power Module VPPM (Power Supply)
The EPIQ’s main power supply module or VPPM is located in the rear
lower enclosure of the system. It provides automatic worldwide AC
voltage regulation, isolated AC outputs for peripheral equipment,
medically isolated DC voltages for the system, and a Smart Battery
System (SBS) compliant charging system for use with the optional
lithium-ion batteries.
Some key points to be aware of:
 Voltages are distributed to the power regulator board (PRB) via
the backplane.
 The system monitor is powered by VDC_SYS voltage (+24 Vdc). It
is not powered by the battery, to reduce battery load.
 When activating the control panel articulation solenoids, the

All ATX and newer
power supplies use the
PS_ON signal to power
up the system. The
power supply remains in
stand-by mode when
the system is plugged in
and the system is off.
Note: This mode of power
up is for moving the
system.
