DC Power System is an integrated power system containing rectifiers, optional converters, intelligent
control, metering, monitoring, and distribution. A power system with List 27 distribution cabinet is usually a part of a configured
cabinet system. However, there is a stand-alone model available which is tested in a 65°C ambient. It does not fit into a standard relay
rack but can be mounted in non-Vertiv cabinets. A power system with List 7 distribution cabinet can be ordered as part of a
configured system to be mounted into an equipment cabinet designed for the power system or as a stand-alone system to be
mounted in a relay rack.
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.
Distribution Cabinet
The system always includes a distribution cabinet, which provides DC distribution through fuses and/or circuit breakers. The
distribution cabinet may house the controller (depending on system configuration).
List 7: The List 7 distribution cabinet accepts one (1) distribution panel (List BW). List BW distribution panel provides dual voltage
load distribution (-48 VDC primary voltage and +24 VDC secondary voltage) and -48 VDC battery disconnect positions. This
distribution panel is configured to accept bullet nose type circuit breakers and TPS/TLS fuseholders.
List 27: The List 27 distribution cabinet accepts two (2) distribution panels. A variety of distribution panels are available that provide
load distribution and dual voltage load distribution for use with -48 VDC to +24 VDC converters or -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), low voltage battery disconnect (LVBD), and in a
List 27 a manual battery disconnect (depending on available configuration options).
