Power Supply System
5-6-1 Electrical Power
The Vivid™ S5 N and Vivid™ S6 N system can operate between 100 and 240 V at 50/60 Hz via an
AC/DC converter which supplies a 20 V DC output and 4.5 amps.
5-6-2 Introduction
The power system is composed of three main building blocks:
• AC Distribution Box - providing the necessary mains isolation and generating 5 V, 12 V and 20 V
DC voltages. See Table 5-16 "Destinations and Voltages" on page 5-38 for the destination and
details of each voltage.
• AC Distribution Panel - provides a single isolated AC outlet for an integrated BW Printer and two
isolated power outlets for optional connection of external peripherals.
• DC/DC Power Supply Unit - located inside the cabinet cage assembly, provides the Vivid S5 N or
Vivid S6 N system with both Low Voltage and High Voltage power, and also enables recharging of
the battery.
- The Power Supply Unit controls the following main functions:
* Input switching stage - selects between the external DC source and the internal battery
* Back End Low Voltage power supply (LVPS)
* Standby power supply
* Front End Low Voltage power supply (LVPS)
* Front End High Voltage power supply (HVPS)
* Battery charger controlled by the Power Management controller
* Control circuitry (used for monitoring, charger control and auxiliary functions).
* The PS communicates with the host CPU via the SMBus
