2System Description
+12 VDC @ up to 2200 Amperes Power System
The NetSure ITS Model PSS12/2200-19BC 12 VDC Power System is an integrated power system containing a main module mounting
assembly, rectifiers, intelligent control, and monitoring. The NetSure ITS Model PSS12/2200-19B is a companion expansion assembly.
A system consists of the following components.
NOTE! The installation may consist of one (1) main module mounting assembly and up to two (2) expansion module
mounting assemblies, or all main module mounting assemblies. In installations with one main module mounting assembly and
up to two expansion module mounting assemblies, all module mounting assemblies are on one DC bus and are controlled by
a single SCC controller. A common CAN bus is shared across all module mounting assemblies and all rectifiers load share
and all rectifiers are load managed via the SCC. In installations with all main module mounting assemblies, each module
mounting assembly is on a separate DC bus and each module mounting assembly is controlled by (contains) a separate SCC
controller. A separate CAN bus exists per module mounting assembly, rectifiers load share per module mounting assembly,
and rectifiers are load managed via an SCC per module mounting assembly.
Main Module Mounting Assembly
The main module mounting assembly houses up to nine (9) rectifier modules, plus the SCC controller.
SCC (System Control Card) Controller: The controller provides power system control, monitoring functions, and local/remote alarm
functions. The controller also provides data acquisition, system alarm management. The controller provides an Ethernet port for
remote access. It also comes with SNMP capability for remote system management. Operation of the SCC controller requires a
master upstream supervisory and control unit, such as the Avocent UMG, connected to the system’s Ethernet port and utilizing an
SNMP interface. Refer to the SCC Controller Instructions (UM1M520HNA) for more information.
NOTE! The rectifiers will continue to operate, if the SCC controller fails. The rectifiers will work, if the system is powered up
without an SCC controller; however, an SCC controller is required to get any monitoring/status information from the system.
The application should be designed with an SCC controller.
