Ethernet Switches and Media Converters

Network Appliances, Gateways, Firewalls and Security

MasTec carries a broad range of Industrial Grade managed and unmanaged Ethernet Switches and Fiber Switches and Media Converters.

Between the manufacturing companies listed below, you will find exactly what you require for your industrial site and many IT sites also.

If you need POE there is a growing selection.

If you need EOP adaptors, we have these also.

If you need Ethernet to Modbus gateways, we can provide quite a range to choose from.

Many of our Wireless Routers and Gateways also container ethernet switches.

PoE (Power over Ethernet) technology is now very mature and still expanding in uses.

POE is made possible by the injecting DC Power into some of the 8 wire in an Ethernet Cable.

There are two types of POE

Mid-span: +48VDC is delivered across the Ethernet cable using the unused pins (4, 5, 7 & amp; 8).

End-span: +48VDC is delivered on on the same pins used for data (1,2,3 and 6).

Usually POE is a high DC voltage > 24, sometimes much higher > 55 VDC.

This injection usually takes place at the Ethernet Switch or with a POE Injector product.

However now there are Computers and PACs that do the DC Power injecting also.

At the far end of the Ethernet Cable an Etherent DC Splitter which brings out the DC and passes through the Ethernet data. The Splitters convert the POE voltage to standard voltages such as 48, 24, 18, 12 or 5 VDC.

It is possible to pump quite a lot of power down an ethernet cable > 100 watts and still have reliability in DC supply.

So imagine you are setting up video survellliance. All the cameras are 12VDC and TCP Gigabit Ethernet for the image data. Just plug the camera into the splitter for the DC power and the ethernet cable and you are done. You do not need to be near AC power to set up the camera, offering great placement freedom.

The same is true of course for DAQ systems that have ethernet data connections, see some of the manufacturerss in the list of suppliers.

POE is very convenient and saves a lot of installation time and money. If you are doing DAQ work there is no need for PSUs. Just plug the Remote DAQ into a splitter and ethernet data cable and you are done.

And of course the Ethernet Cable is a great high speed data pipe for DAQ. Mastec has a LabVIEW system controlling 4 DAQ units running at full data rates of >100KHz each and the Laptop connected to the DAQ via a POE Ethernet switch, doesn't blink.

More about loggers and recorders...

The new Tiny USB stick loggers are so low priced, and have such a versatile range, you can almost log any signal with them. However they log quite slowly and this may be an issue.

Fast loggers have a bigger price tag and are more sophisicated large memories, large IO, Networking, Wireless, Displays and more.

Another type of logger is the wireless logger, that collects signals from multiple points at the same time using Wireless technology.

The most versatile logger is the Laptop with a DAQ card or a USB DAQ module. Most vendors now supply free logger software for their DAQ hardware.

AC & DC Power loggers have a built in circuit for managing AC and DC high voltage and currents. Most AC power loggers give Volts, current, watts PF, KwHr and many other parameters.

MasTec has both paperless recorders with LCD displays and older style paper recorders.

REGATRON regenerative systems allow for the outermost freedom in system design due to separate feeding and regenerative system parts

TC GXS Series


Series Overview

TC.GXS is a series of unidirectional high-power DC sink (electronic load) units based on the utmost state-of-the-art circuit techniques. The AC input block is made up of a fully active PFC structure which eliminates the need for external means for power factor correction. In addition, an active medium frequency converter topology provides outstanding wideband dynamics and optimum stability even with complex circuitry. As all REGATRON DC power supplies, TC.GXS disposes of a powerful multi-processor architecture offering not only full digital control, but also onboard real-time data processing. By this, the versatile function engine TFE is on disposition or the famous ‚Application Area programming‘, enabling an y=f(x) transfer characteristic for the unit (option).

• 0 - 2000 VDC, 20 kW up to MW range
• Easily scalable and configurable by user in the field
• Finely graduated voltage- / power levels
• Air- or liquid cooling
• 2-channel safety interface and user safety options
• Operating and diagnostics software TopControl
-• ntegrated 8-channel scope for quick diagnosis
• High-level world-wide customer support
• Cabinet turn-key solutions

DC Loads with AC Regeneration


Smart energy saving!

Managing your costs can give you the leading edge over competitors. With AC Regeneration, you can capture wasted energy generated and redirect the power back to the utility and synchronised to the power grid. At the same time, reduce greenhouse gas and harmful gas emissions.

IT8300 Series Regenerative DC Electronic Load

It not only can simulate various load characteristics, but also can feed power back to grid without pollution. IT8300 series unique regenerative function can convert the Battery Absorbed DC Power into AC power and feed it back to local grid. This can be single phase or three phase AC Power. This regeneration of the DC from the batteries back to AC power eliminates the usual heat dissipation experienced with most DC Loads (without Regen) to a minimum and saves energy costs, adapts requirements of global energy-saving and emission reduction at the same time.

IT8300 adopts high power density design, e.g. for 3 U size, it can absorb power up to 10.5 kW.

IT8300 supports master-slave paralleling and current equalized distribution, which can expand the power up to 105KW or more.

Moreover IT8300 has multiple functions such as the automatic grid-state detection, on-grid electricity accumulation, anti-islanding protection, battery-test function, dynamic mode, LIST function, etc.

The built-in interfaces include LAN/USB/RS232/RS485/CAN interfaces.

The various functions make IT8300 series suitable for high-power power supply, storage battery, photovoltaic battery, electric vehicle, energy storage system, etc
