The USB Type C connector is now being adopted by all the major manufacturers of mobile devices (phones, tablets, etc) and has already been incorporated into some laptops. This is not only because of its small form factor and the fact that it is reversible, making it simpler and easier to use, but also because it enables significantly faster charging than was possible with the USB Type A connector, whilst at the same time (for relevant devices) replacing all former AV/data connections, such as VGA, HDMI, USB-A, RJ45.
TUFA+C from OE Electrics provides both the new USB-C port, for enhanced fast charging of compatible devices, plus a USB-A for charging legacy devices – suiting users with any USB powered device old or new.
TUFA+C also has the unique benefit of being replaceable through patented TUF-R technology; perfect for areas of high traffic such as airports, schools and hospitality, where, if damaged through misuse or worn out through high usage, TUFA+C can quickly be replaced, in-situ, without the need for an electrician or even turning off the power; or, to keep pace with technology, it can be exchanged for an upgraded TUF solution. When used in combination with country-specific mains sockets, users can configure the complete power solution to meet all their power/charging needs, present and future TUFA+C has been independently certified to international safety and EMC standards and every unit is extensively tested during the manufacturing process to ensure long-term reliability. From airports to offices to libraries to laboratories, TUFA+C provides the best of both worlds; USB-A charging for legacy devices and the more advanced USB-C charging for new devices. We are all slaves to our devices; we rely on them, not only socially, but even more so for business. They have become a necessity. This all means if you manage a place of work, a school, an airport, library or train – people will be relying on you to provide safe, easy to access, fast charging. TUFA+C provides all of that and more. TUFA+C can be fitted into any OE Electrics power module making it incredibly simple for you to provide the best solution for you, your clients, and their clients. And where OE Electrics doesn’t have a product that fits your space – we’ll help you design one to suit.

TUF A+C25W Charger Dimensions:
TUF A+C fascias are available in Black, grey, white, or stainless steel.
The procedure for replacing a TUF-R charging socket in situ, has been designed to be quick and simple with no need for a qualified electrician. Simply remove the TUF-R fascia and extract the TUF module with the supplied tool, insert a new module until the integral clips engage and finally refit the fascia. The process taking no more than a few minutes and without the need to disconnect the AC supply.
Power Supply Overvoltages EXPLAINED!
Overvoltage is a serious issue that can lead to damaged equipment, fire or injury. Rather than explain it with technical jargon, imagine a round-bottomed bowl.
|A round-bottomed bowl, which is free to move, will rest evenly on a flat surface||With three equal weights, clipped evenly around the rim, the bowl will remain balanced||With different weights, the bowl will tip to one side, the heavier weight being lower|
Transposing this to a 3 phase electrical system, where the weights are considered electrical loads (eg: appliances) and the voltages are related to the height of the weights above the flat surface; when the electrical loads connected to the system are the same, the electrical system is a “balanced 3 phase system”. The voltages of the phases (heights of the weights) are all the same – at 230Vac (or 110Vac in some countries
When the electrical loads connected to the system are different, the electrical system becomes unbalanced. The voltages of the phases (heights of the weights) become different with some being higher than 230Vac and some being lower Single phase appliances (eg: computers) won’t generally suffer an issue with an undervoltage (eg: 130V), they simply may not work. However, they DO NOT like an overvoltage (eg: 330V) which can lead to overheating; damaged components; or even short circuits that could cause an electrical hazard or fire.
In the real world, two examples may be:
Within a business, there may be 3 different areas running on separate phases. If one area has big machines with motors, a second area has low power computer equipment and a third area has nothing – then it is easy to imagine that the electrical system will suffer different effects caused by the loads in each area. If something is not done the system will be unbalanced with higher and lower voltages around the business. However, don’t just think that it is the business’ own loads that have an effect.
In a business centre, where separate businesses run on different phases of the building supply, if one company runs some large loads (eg: printing equipment), another runs small loads (eg: computers) and a third, only employs assembly workers with no electrical load, then the buildings’ electrical system can be unbalanced. One business may be experiencing low or high voltages, due to another business, through no fault of its own. Effectively, overvoltages can be caused by external factors over which you have no control.
So, how do you solve overvoltages, especially when you may not be able to control the mixture of electrical loads? (ie: weights on the rim of the bowl)
How do you keep the system balanced?
Well… in the bowl scenario, you would glue the bowl down, so that it can’t tip over.
In an electrical system, the equivalent is to tie the Neutral of the Installation to the Neutral of the Supply. This way, the voltages between neutral and the 3 phases will stay the same (230Vac or 110Vac as appropriate).
Tieing the Neutrals together is standard electrical installation safety practice and would be checked, by a qualified inspecting electrician, before a building is handed over to the owner.
However, during the process of electrical installation, there is always the possibility of human error and it may only be after energizing the system, for electrical testing to be done by the inspector, that a loose/‘floating’ neutral is discovered. But once fixed, the problem should not re-occur unless the electrical system is later modified or repaired. Until recently, the only types of equipment that may be pre-connected to an untested supply would tolerate an overvoltage for a brief period (eg: lighting). Sometimes, it is the effect on these appliances, that is the first sign of a floating neutral to the installers, as the lights will flicker or be too bright/dim.
Certainly, no-one would consider connecting computers or other sensitive electronic equipment to an untested supply, because the effect on these types of equipment can be dramatic and potentially dangerous. The issue – and reason for this document – is that, as a result of increasing popularity surrounding mobile devices
that charge from a USB outlet, new/modified electrical installations may have USB chargers installed from the outset. e.g. in a wall socket, or as part of the soft wiring. However, USB chargers contain sensitive electronic equipment and if subjected to an overvoltage, as a result of being energized on an untested and incorrectly connected electrical system, they could be irreparably damaged.
TUF is a piece of sensitive equipment and it MUST NOT be connected to an untested electrical system.
If TUF is connected to an untested supply, and that supply has a loose/’floating’ neutral, causing an overvoltage, then TUF will simply become the ‘coal miner’s canary’ and will expire, before anything else, when the installation is first energized for testing.
OE Electrics will not warrant a TUF that has been exposed to an overvoltage or connected to an untested electrical supply OE Electrics accepts no responsibility for any consequential damage caused by TUF as a result of energizing it on an untested supply or subjecting it to an overvoltage.
