Introduction
Sageon III Power System
PM990-8800-00, Rev. 9
1-2
As indicated above, the Power System is divided into two areas: distribution and power conversion. The system is shown in Figure 1-
1. It provides 12 power conversion positions at 600A or 24 power conversion positions at 1200A for rectifiers and 6 distribution
groups (in 3 distribution tiers) with a user-specified quantity of AM1 circuit breakers, & GJ1 circuit breakers..
Power Conversion
Plug-in rectifier models are available in –48V. It employs modular switched-mode rectifier technology for highly efficient, low cost,
reliable operation. Each –48V rectifier can source up to 50A. The quantity of rectifiers is determined by the user to accommodate the
application. A maximum of 24 rectifiers can be installed in a unit.
Distribution
A unit can include up to 60, 5-100A AM1 circuit breakers. Up to 8, 100-450A GJ1 circuit breakers can be installed, however, each
group of 4 GJ1 type breakers reduces the available AM1 positions by 10.
Circuit breaker and fuse kits are ordered separately to accommodate the application. For AM1 type breakers, the load supply and
return connections use two-hole wire lugs for 1/4" studs (5/8" center-to-center). The supply cable is bolted to a distribution assembly
that has two 1/4-20 studs and the return connection is bolted to the return bus bar that also has 1/4" studs.
Where higher current GJ1 type breakers are specified, the load supply connection is a 3/8" ring lug bolted directly to the breaker
terminal. The return connection is bolted to the return bus bar using a two-hole lug for 3/8" bolts (1" center-to-center).
Battery Strings
Battery charge and battery return can facilitate eight sets of 2-hole lug wiring for 3/8 inch diameter studs on 1 inch centers.
Operator Panel
Mounted in the system is a modular, hot-swappable controller which includes a high-resolution 2-line digital display for monitoring of
the Sageon III Power System output current and voltage. Six push buttons are available for operating the Sageon III Power System,
selecting display information, and for changing editable parameters. A complete System configuration can be created at the operator
panel. Three System status LEDs are provided.
Communications
PC-based configuration and monitoring is available with the UNIPOWER SageView™ software. SageView is a tool to exchange
configurations and operating data between the Sageon III Power System and the PC on which SageView is running. Local PC access
is provided through a supplied USB-B connector on the front panel of the controller using the SageView software.
Remote PC access across an Ethernet network is also standard. The PC must be running SageView software and have a unique IP
address on the network. An Ethernet RJ-45 jack is provided for connecting to your company’s intranet or to the Internet. A unique IP
address is required for each Sageon III Power System. Remote access is also available via an SNMP/Ethernet board.
Alarms
Activation of customer-supplied alarm annunciators is accommodated by form-C relays. The relay state is user selectable between
normal mode (normally de-energized) and failsafe mode (Normally energized). These relays provide for external annunciation of the
alarms and are fully user configurable. Refer to SageView help for configuring these relays.
Block Diagram Description
A simplified block diagram of a 48V Sageon III Power System is shown in Figure 1-2. Single-phase or three-phase power is supplied
from the user’s AC electrical service panel.
