Electrical Safety Starts from the Connector

High Voltage WarningDo you know one common challenge for devices used in areas such as filter and inductor construction, energy distribution and power supply production is Electrical Safety i.e. how to lead the high power through the panel wall safety.

Finding the right wall feed-through terminal block to address electrical safety is a challenge as there are not many suitable solutions for high current and large wire cross-section. It is also unlikely that the manufacturers  will choose the feed-through terminal blocks as early as the design stage. This often leads to manufacturers designing their customized solutions out of sheer necessity; thus resulting in problems such as maintaining touch protection or insulating the current bar from the device housing.

The device manufacturers may also face problem obtaining the necessary certification for their devices. If the device is to be used worldwide, IEC 61800-5-1 and UL 1059 certifications are required. Many solutions in the market are unfortunately not adequately certified.

High Current Feed-through Terminal Blocks

Phoenix Contact offers an extensive range of high-current feed-through terminal blocks for various applications. You can find both pluggable feed-through terminal blocks and feed-through terminal blocks for permanent connections. The pluggable feed-through terminal blocks permit quick replacement and are thus service-friendly. In addition, the conductors can be preassembled. However, feed-through terminal blocks for permanent connections are more economical.

Do you know Phoenix Contact has been providing these feed-through terminal blocks for almost three decades?

Device manufacturers can choose the connection option to fit the application: fast push-in connectors, T-lox, conventional screw connectors, or simple bolt connectors. The connection areas range from 4 to 150 mm2 and the current-carrying capacity is up to 309 A.

These connectors come in standard and moulded designs, either with horizontal or vertical connection directions. The moulded version ensures high leakage resistance, even when a small amount of moulding compound is used. The product range provides various connection options for space-saving connections in all installation locations. This means that device manufacturers can flexibly select the connection type, direction, and cross section.

Copper Connections – Why Settle for Less?

Have you ever wondered what your current screw terminal block is made of? Does it have copper connections or steel connections?

Similarly, have you ever wondered why a wire is made out of copper? I did a search and Google told me this.

“With its exceptional current carrying capacity, copper is more efficient than any other electrical conductor Because of its superior conductivity, annealed copper is the international standard to which all other electrical conductors are compared . … Another advantage is that copper oxide also conducts electricity.” (www.copper.org)

We know that copper is well-known for its good conductivity; that is why it is used in most electrical components. What about Terminal blocks? You will be surprised that most of the screw terminal blocks in the market are not made of copper. Not convinced? I dare you to take the magnet challenge

Remote Monitoring via the Mobile Network

Mobile Network Architecture

We are all available 24 hours a day. We have at least one cell phone, use the Internet on the go every day, and learn about the latest global news through our communication media. Having information at one’s fingertips is now essential to us all and nobody wants to give it up.

Think about the global competition in industrial production, which calls for us to continuously optimize our systems. As a production manager, you need to know at all times what is being produced worldwide on each machine, at what quality level and when the next maintenance interval is due. Such new systems are hardly imaginable today without efficient communication networks, which are essential for reliable system operation. This rapid development in the exchange of information and data that we have experienced in the telecommunications industry in the last few years is about to break into the industrial sector.

Indeed, many of these M2M (machine to machine) applications will be implemented over telecommunications networks. Now is the perfect time to consider these topics, applications, and technologies in the industrial sector.

Therefore I would like to share with you one of our success story implementing remote monitoring over the mobile phone network. The idea is to monitor remotely several paramaters on the oil well that is scattered in locations remotely using the GSM modem.

By doing this customer can get data more effective and efficiently compare to previously that one must go to every site locations and get information on the pressure and temperature at the oil well.

Solar-powered RTU

In this project we even integrate a solar system to power up the RTU and GSM modem since the location is remote and there is no power available. System architecture can be seen in the picture below:

RTU and Solar Power

Our GSM modem has a feature with dual sim cards which means when it detects low signal reception from one provider it can automatically transfer the communication to the other sim card. This is to maintain data availability.

We also set up a VPN tunneling in order to get a secure data transmission.

With this configuration, now customer is able to monitor oil wells data from office directly. They just need to select which location they want to monitor.

If you would like to know more on the remote communication using GSM modem, please do not hesitate to contact us. Thank you.

Solar Technology 1500VDC

Today, solar technology in the Philippines still revolves around 1000VDC, which is more or less 5 years old already.

However, due to increasing number of foreign investors in Solar projects in the country, this has resulted in a growing demand for the latest developments in Solar technology . With this we had received numerous request from System Integrators, local end users, and electrical contractors for 1500VDC technology.

1500 VDC systems will allows installers to reduce installation time, string size, wire costs etc.

Being a provider for solutions and products in the solar energy area for many years, Phoenix Contact has been keeping abreast on this demand.

The 1500VDC string combiner boxes from Phoenix Contact meet these requirements of collecting and distributing string currents, protecting the individual modules against damage from lightning and surge voltages, and monitoring the performance of the system.

Solar Seminar 2017

Solar Seminar Philippines

We decided to conduct a Solar Seminar featuring Phoenix Contact’s new 1500VDC technology to address this demand. Held recently at Luxent Hotel in Quezon City, Philippines, our speaker highlighted and focused on 1500VDC Technology and its derivative products like our String Combiner box.
