overview
The RT9 Powershelves are a range of high power density turn-key
DC power solutions providing modular power, distribution,
monitoring and control.
Rated for continuous operation from
-40°C to +70°C, over a wide AC Input
range 85-300VAC.
Tolerates loss of

indefinitely.
Highly Integrated
Covering both 48VDC and 24VDC, the RT9 Powershelves are
highly integrated including battery distribution, battery current
limiting, battery temperature sensing, low voltage disconnection,
short-circuit and reverse polarity protection (AC distribution
modules are available for integration in the shelves).

description
Power Shelves
The RT9 Powershelves are
19” rack mount units and
are available in 2U, 3U, 4U
and 6U high solutions. In
each 1U rack space, up to
two rectifier modules can
be mounted side by side.
The Powershelves provide front to rear ventilation, with
zero clearance required above and below the units,
maximizing capacity for revenue generating
equipment. The power shelves operate over a wide
AC input of 85-300VAC and are equipped with user
DIN rail terminations at the rear, configurable for single
or three-phase. A 1U shelf can be configured as AC
distribution for up to 8 rectifiers. Copper termination
bars with M6 holes are provided at the rear for DC
load and battery connections. A user specified load
distribution unit can be connected to the system at
the load terminations provided.
Rectifier Module
The RT9 48V/25A and
RT9 24V/50A are switched
mode rectifier (SMR) modules
that deliver up to 1.4kW of
output power and up to 30A
output current to 48V and up
to 60A in 24V nominal systems.
The RT9 suits nominal AC supply voltages between
208VAC and 240VAC and will continue to operate
down to 85VAC at reduced power. The RT9 will
operate up to 300VAC and will not be damaged
when exposed to overvoltage of up to 440VAC. The
RT9 is internally protected against voltage transients.
The small dimensions of the RT9, with efficiencies
greater than 90% at full load, allow high shelf power
density. Each rectifier is cooled by inbuilt speed
control fans, allowing operation at temperatures up to
+70°C. Power output is internally regulated to prevent
rectifier damage under abnormal environmental
conditions.
System Management
The hot-pluggable MiniCSU-3 controller manages the
Powershelf and provides local and remote user access
to all the system parameters and alarms. The MiniCSU3 coupled with the WebCSU interface option provides
HTTP, SNMP, automatic system time synchronization
capability and TCP/IP access for the WinCSU-2
Windows® based remote monitoring and control
software. The front panel includes a 2x16 character
display, menu navigation keys and a USB port for local
PC access.
The MiniCSU-3 digitally controls the system voltage,
rectifier load sharing, battery management/
monitoring, and is designed for fail-safe operation. All
system parameters are backed up within the
Powershelf, independent of the controller, to enable
“hot-swap” replacement of the controller without
reprogramming or loss of alarms history.
Other features include ambient and battery
temperature sensing, five user programmable alarm
relays, AC voltage monitoring and alarm and event
logging.
Battery Management
The integrated battery distribution module provides
battery current monitoring, up to 4 circuit breakers,
circuit breaker trip detection, a low voltage
disconnect switch (LVDS) and reverse battery polarity
protection circuitry. These features coupled with the
enhanced battery management function of the
MiniCSU-3 provide battery charge current limiting,
adjustable charging schemes, controlled current
discharge testing, battery temperature compensation
and voltage monitoring of cell or monoblock strings.
Batteries
A wide range of batteries including flooded, VRLA,
Lithium-Ion
Polymer
and
Nickel-Cadmium
technologies can be used with the RT9 Powershelves
and may be sized to suit required reserve times and
loads.
