For many of your applications, it makes sense to connect
multiple power supplies with data lines in order to actively
monitor and optimally control active processes. For such a
network to operate reliably, the connections must ensure
secure and loss-free data exchange.
Data connections used for transmitting current and voltage
values require a connection system comprising PCB terminals
or connectors. Today, RJ45 PCB sockets are mainly used for
transmitting input and output voltage levels.
Our interfaces, signal and data ports meet all the
requirements for providing accurate and reliable data
transmission. This includes our digital 2-wire interfaces using
connection technology comprising PCB terminals or
connectors. They are available in pitches of 3.50 mm or
5.00 mm. Our shielded RJ45 PCB sockets are worth
considering as an ideal bus solution. They can also be used
in harsh and electromagnetically charged environments,
support high data rates and are especially future-proof
thanks to Cat 5 or Cat 6 standards. Our RJ45 product range
also includes alternative versions for different applications
and design requirements.
The best solution for feeding current through the housings of
your devices are feed-through terminals. They are ideally suited for
discrete or enclosed devices used in power supply applications.
The device feed-through terminals in our WGK series allow
currents of different magnitudes to be fed through housing walls.
Two housing halves that snap together provide an easy-to-install
and readily detachable connection. The touch-safe insulated
housing has the UL 94 V-0 ammability rating and can be
marked with labels from our standard range. Weidmüller device
feed-through terminals in the WGK series are available for
currents up to 232 A and rated cross-sections of 4 mm² to
95 mm² (AWG 4/0). They support different types of connection
from encapsulated solder terminals to maintenance-free
clamping yoke screw connections and “PUSH IN” spring
connections. In addition to the horizontally designed standard
variants with two housing halves there are versions with vertical
wire entry as well as versions for connecting cable lugs on the
inside face of the housing. All variants are optionally available
with spigots for convenient side-by-side mounting.

3. Control output
Permanent functionality guaranteed
Constant monitoring of the secondary output voltage is vital for
ensuring the reliable functioning of the entire system. Critical
operating conditions are identied in good time and reported to
the controller. Losses in output power can be queried directly on
the machine or via remote monitoring. In addition to general
function monitoring, comprehensive diagnostics are also possible
and serve to actively control and optimise processes.
To complete these tasks, the supply voltage must be monitored
reliably and with absolute precision. This means that the trans-
mission of current and voltage to the connected instruments
must be as loss-free as possible.
OMNIMATE connectors and PCB terminals help to ensure that
precise values are transferred and can be directly connected to a
relay output (240 V AC, 2 A) or transistor output (30 V DC, 100 mA).
While the versions with vibration-resistant clamping yoke screw
connection technology permit multiple cross-connections to oth-
er devices, the impressive feature of the plug-in connectors is
their absolute protection against mismating through integrated
coding. All products are characterised by extremely low contact
resistance and are available in 3.xx and 5.0x pitches and for con-
ductor cross-sections ranging from 1.5 mm² to 2.5 mm².

The output side of a power supply is generally loaded with low
voltages and high currents. The main task of the connection
system on the secondary side is to prevent contact resistance
and keep losses as small as possible.
The highly conductive metals used in OMNIMATE device
connections ensure that contact resistance is reduced to a
minimum. They also meet all the requirements on the secondary
side for ensuring optimum performance and the safety of people
and materials during everyday operation. They are designed for
output voltages from 1.5 V DC to 250 V DC or 12 V AC to 250 V AC
and feature impressive overload resistance.
OMNIMATE PCB terminals and connectors in the screw
connection version allow multiple devices to be cross-connected.
This is useful for increasing the output performance or setting up
a redundant power supply.
OMNIMATE device connections are available as PCB terminals
and connectors for a wide range of applications. The vibration-
resistant connection system available in pitches from
5.0x to 15.00 mm with “PUSH IN” spring connection or clamping
yoke technology guarantee secure and cost-effective cable
connections.
The quality of the internal connections of a power supply
has a major inuence on the reliable operation of machinery
and equipment. During operation, the individual PCBs and
functional units need to withstand high temperatures and
maintain consistent performance even under uctuating
ambient temperatures.
The temperature in the control cabinet can quickly rise to
above 60 °C. It is usually sufcient to cool down the installed
devices. If the cabinet is also exposed to direct sunlight, the
operating temperature can be higher still. But even at such
high temperatures, a power supply still needs to function
reliably. If not, the highest achievable output power
decreases with each increase in temperature.
Weidmüller device connection technology will never let you
down, even in extreme temperatures. OMNIMATE
connectors transfer high-frequency power reliably and utilise
high-temperature materials to provide high reserve capacity
– even at extreme temperatures. Different conductor outlet
directions also provide maximum design exibility even for
small components. Suitable OMNIMATE Signal connectors
are available in 3.50 mm or 3.81 mm pitches and also
5.0x mm.

Weidmüller electronics housings are the intelligent package for
your power supply components. They ensure perfect integration
in the system environment and provide a future-proof platform
for a variety of electronics applications. For ease of assembly,
CAD data for the PCBs is provided for all housings. Screw and
tension clamp terminals are available for all connections.
When it comes to electronics housings Weidmüller is a byword
for competence and quality. We can provide you with a suitable
housing solution for all kinds of application. This also applies to
our assembly housings in prole form. This exible modular
system of plastic proles and carrier modules, which, thanks to
a combination of standard pitches that allow side by side
mounting in any arrangement and precisely cut lengths, creates
the perfect balance between exibility and cost-effectiveness.
Pitch proles with standard widths of 5 mm to 45 mm allow all
standard PCB formats to be mounted, while variable heights
ensure maximum packing density, even with large electronics
components. The different installation variants mean that direct
mounting of the housing is as easy as clipping components
onto a DIN rail Solid cover hoods provide protection against
external inuences. All in all, the consistent synergy between
design, connection technology and functionality.
