Products Editor’s Choice Are your panels too hot to handle?
Rising ambient temperatures can lead to overheating electrical panels. By limiting the maximum temperature to which equipment is exposed, appro- priately selected enclosure cooling solutions can prevent a large propor- tion of failures.
Rittal’s range of cooling products includes fan and filter units, air/air heat exchangers, thermoelectric cool- ers, cooling units, air/water heat exchangers and chillers. Fan and filter units force the cool, clean air sur- rounding panels through them, where- as air/air heat exchangers recirculate the air inside the enclosure, cooling it down using only the temperature of the ambient air and therefore may be used in dirty environments.
Cooling units and air/water heat exchangers may be used to cool the air inside an enclosure to a temperature lower than that of the ambient, again recirculat- ing the air inside the enclosure, and are suitable for contaminated atmospheres. Cooling units provide a stand alone solu- tion and air/water heat exchangers use water and a remote chiller.
Intelligent surge protection
Offering intelligent monitoring of every voltage limiting compo- nent of a protective circuit, the Plugtrab PT-IQ is the latest range of surge protection devices from Phonenix Contact.
Rittal also has a range of climate
control products and are able to assist in determining whether climate control is necessary.
RiTherm, a software package that allows climate control requirements to be both quickly and easily calculated, may be used to guide you to the most suit- able, correctly dimensioned climate con- trol solution. Rittal

Rigid conductors and flexible ones equipped with end sleeves can be inserted directly into the terminal sockets quickly and without fatigue. No special tools are needed to disconnect wires. An integrated button allows you to disconnect each wire easily by pressing it with a small flat blade or cross head screwdriver. When it comes to installation the surge protection devices fea- ture a controller which supplies up to 28 protection devices with volt- age over mounting rail connectors. At the same time the status of all protection devices is trans- ferred to the controller. The wiring work is minimised as the supply, as well as remote sig-

The new PV-Stick plug-in connector with PUSH IN connection, from Weidmüller, offers crimp-free and plug-in installation for photovoltaic systems. The new connector complies with the DIN EN 50521 stan- dard, in addition to being TÜV approved.
The PUSH IN connection system saves approximately 50% of the time required for cabling solar systems. The plug-in connectors are connected securely in just a few steps - insert the stripped conductor in the plug-in connector and turn the screw cap. A clearly audible click indicates a secure connection.
A clearly visible marking on the screw cap acts as an accurate indi- cator for determining the stripping length. Wire cross-sections of 4mm2 or 6mm2
can be attached to the PV-Stick in a matter of seconds, without the need for wire end ferrules, crimp contacts or crimping tools. The rating data is 30A and 1,000V DC (IEC). With its PUSH IN connection system and Type 4 connector face, the PV Stick dispenses with the need for crimp contacts and crimping tools, thus avoiding contact errors. In addition, the ergonomic and functional design of the PV plug-in connector enables trouble-free assembly, even under difficult conditions, such as when working at heights. Weidmuller

To allow the collection and interpretation of electrical data in one central place, Schneider Electric has launched Power Monitoring Expert (PME). The PME, as part of the StruxureWare software, combines all of the independent mecha- nisms of metering, monitoring and simple control with a user defined interface to create one solution. This scalable technology has been designed for medium sized buildings, such as retailers, health centres and small offices, through to large enterprises and multi-sites. Working as a web-based platform, PME software collects and organises data gath-
ered from the facility’s electrical network and presents it as meaningful, actionable information via a web interface. PME retrieves data from meters, breakers, drives, Acti 9 solutions and relays to mon- itor energy consumption. The software then allocates costs to departments or process- es and can calculate the cost of energy such as water, air, gas, electricity and steam, based on tiered rates, TOU, demand charges and taxes. It can even produce accurate tenants’ energy bills, identifying billing discrepancies. The result is that users are able to see, measure and manage energy and power data
across an entire enterprise in order to identify areas for improvement and verify the effective impact of energy measures. Users can also use the data to perform compara- tive calculations and show trends to identify further savings areas, whilst also enabling effective fulfilment of mandatory carbon reporting. PME can be used to monitor power availability and reliability of the system, sending an alarm remotely to the personnel’s mobile to alert him/her of a power interruption. Schneider Electric has developed specific versions of the PME for market segments including data centres and healthcare, to reduce the cost of implementation and facili- tate a more targeted approach to efficiency for customers within a specific segment.
