PSM busbars

Article number: DK 7856.016

One or two infeeds, with on or three phases, redundant after changing the plug-in module's direction of connection. With measurement option in conjunction with the CMC III system.

Article number:
DK 7856.016
Design
With measurement of voltage, current and power (consumption), via CMC-TC, remote-controllable
Product description
The modular system facilitates basic configuration of the racks, thanks to a vertical support rail with single-/3-phase infeed. The various socket modules to supply the active components may be snap-fitted into the support rail. This can even be done whilst the system is operational, because the support section is shock hazard-protected.
Benefits
Modules may be retrofitted whilst operational.
Technical specifications
Each plug-in module picks off a phase on the support rail, either from infeed or from the redundant infeed, depending on the direction of connection.
Depending on the design, single-/3-phase construction with a maximum current of 2 x (3 x 16 A/32 A).
3-phase redundant infeed supported.
The redundant circuit is completely separate from the 3 phases of the support rail.
Modules may be equipped with integral overcurrent protection, so that only the affected module is deactivated in the event of an excessively high current. The other modules remain operational.

Power System Module busbar with measuring system

The modular system enables a basic configuration using
vertical support rails and a three-phase supply to be
installed for each rack. The system also has a
redundant power supply configuration as a second power
supply has been provided for each of the rails. The
vertical support rails ensure that the slots can be
used over the full height of the enclosure and the
redundant supply comes from the second separate supply.
Socket modules can be snapped into the support rails.
The contact hazard protection design of the busbar
ensures that socket modules do not have to be fitted in
all of the slots.
Socket modules are available is different country
versions, i.e. IEC IEC320 C13, earthing-pin and F/B,
CH, USA & UK.
A mixture of all of the modules can be fitted in the
rails. 6 socket modules can be used with each 2m rail.
A total of 42 sockets are available if IEC320 modules
are fitted.
The PSM rail measures the active power and the power
for all 3 phases. It is displayed on a local display.
The PSM rail can be remotely administered and
configured in conjunction with the CMC-TC via standard
protocols (SNMP, http). Measuring and monitoring of
the current per phase. Min./max. limits can be set up.
Measuring range 0 -16A. Measuring and monitoring of the
performance per phase. Min./max. limits can be set up.
Measuring range 1 - 6 KW. Alarms indicated by a
flashing display. Remote administration of the PSM
rail, remote limit modifying and monitoring, SNMP trap
message for alarms.

Installation via the plug & play system:

The busbar can be installed in a flexRack(i) without
having to use an adaptor or can be retrofitted to all
Rittal TS / PS racks using a DK 7856.011 mounting kit.
The power is supplied via a 5-pin connection socket
using tension-spring technology.
A pre-configured 3 m connection cable fitted with an
IEC309 AC plug is also available.
All of the socket modules can be upgraded whilst
working.

3-phase overvoltage protection:

Overvoltage protection is available for every 3-phase
supply. Overvoltage protection can also be fitted as an
upgrade. Integrated visual function checks
Overvoltage protection has been designed to meet Class
D requirements (different use with local sockets).

Technical fittings:

3-phase configuration with a max. of 3 16 A
per power circuit
Two separate power circuits per support rail
Redundant power circuit 2 has a completely separate
potential from power circuit 1
The connection direction of the socket module can be
selected to determine if power circuit 1 or redundant
power circuit 2 will be used.
A socket module can be upgraded whilst working
Every module can be selected with / without an
integrated circuit breaker
