The Vertiv™ NetSure™ 5100 DC Power System is an integrated power system containing rectifiers (-48 VDC output), optional solar
converters (-48 VDC output), optional converters (+24 VDC output), optional converters (-58 VDC output), optional inverter system
(120 VAC output), intelligent control, metering, monitoring, and distribution. This power system is available in configurations for 19”
and 23” rack mounting.
This power system is designed to power a load while charging a positive grounded battery. This power system is capable of operating
in a batteryless installation or off battery for maintenance purposes. The power system is designed for operation with the positive
output grounded.
This system consists of the following components.
DC Distribution Cabinet
The system always includes a distribution cabinet, which provides DC distribution through fuses and/or circuit breakers. The
distribution cabinet is factory mounted in the relay rack specified when ordered. Different sizes of distribution cabinets are available
to accept from one (1) to two (2) distribution panels. A variety of distribution panels are available that provide load distribution,
battery distribution, and dual voltage load distribution for use with -48 VDC to +24 VDC converters and -48 VDC to -58 VDC
converters. These distribution panels are configured to accept bullet nose type circuit breakers and TPS/TLS fuseholders. The
distribution cabinet may be equipped with low voltage load disconnect (LVLD) and/or low voltage battery disconnect (LVBD)
(depending on available configuration options).
Controller
NCU (NetSure Control Unit) Controller: The NCU controller provides power system control (including optional low voltage battery
disconnect (LVBD) and low voltage load disconnect (LVLD) control), rectifier control (including a charge control function), solar
converter control, -48 VDC to +24 VDC converter control, -48 VDC to -58 VDC converter control, -48 VDC to 120 VAC inverter
control, metering functions, monitoring functions, and local/remote alarm functions. The controller also supports rectifier temperature
compensation if the system is equipped with a temperature probe(s). Temperature probe(s) may also be designated to monitor
ambient temperature and/or battery temperature. The controller also provides data acquisition, system alarm management, and
advanced battery and energy management. The controller contains a color TFT display and keypad for local access. The controller
provides an Ethernet port and comes with comprehensive webpages for remote access.
