Charges 5 x faster than a standard USB port

The NEW OE Electrics TUF-R5A has been developed for the future. TUF5A was perfect for your fast-paced life, but TUF-R5A offers the same powerful, compact and efficient power delivery with one fantastic advantage: it’s upgradeable! Without the need for an electrician, or even a handyman, when TUF-R Type A+C arrives, you can simply upgrade the module yourself, saving time, energy and money.

The OE Electrics TUF5A (Twin USB Fast) charger with its 5A max output and unmatched 90% efficiency is now available in a unique on-site upgradeable/replaceable format. Developed for high use areas such as Hotels, airport lounges, trains and schools/colleges, TUF-R5Acharging sockets can be replaced on-site without even the need to disconnect the AC supply.

Although our standard TUF5A features enhanced durability 5,000+ insertion USB connectors, inadvertent damage or vandalism of a USB connector is a risk that cannot be ignored by facility managers. TUF-R5A offers a cost-effective solution for the management of this risk by enabling quick on-site replacement of a damaged TUF socket rather than the removal of the complete power module for repair.

Another invaluable feature of the TUF-R5A is that being replaceable, it will allow future upgradeability of your USB charging provision to the next generation type C USB PD charging solutions as these are developed by OE Electrics. Specifying TUF-R5A will help ensure end-user satisfaction and protect your investment in device charging provision.

The procedure for replacing a TUF-R5A charging socket in situ has been designed to be quick and simple with no need for a qualified electrician. Simply remove the TUF-R5A 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 a few minutes and without the need to disconnect the AC supply.

TUF-R5A has achieved its class leading 5A output by boosting internal efficiency up to an exceptional 90% via innovative low loss circuitry. As a result, TUF-R5A is able to charge faster with less power wastage due to heat generation than competitor products and comply with the latest level VI international standards on the efficiency of mobile device power supplies.

TUF-R5A utilises advanced device recognition circuitry to automatically communicate with the portable devices connected so that they can then draw the optimum changing power. Safety has been a design priority and TUF-R5A circuitry includes protection against both input and output current overload and short circuits and, has been independently tested to the latest international Safety and EMC standards.

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, we are after all in the furniture industry, not electrical geeks, imagine a round
bottomed bowl.

  
A round bottomed bowl, which is free to move, will rest evenly on a flat surfaceWith three equal weights, clipped evenly around the rim, the bowl will remain balancedWith 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 as electrical loads (eg: appliances) and the voltages are related to the height of the weights above the flat surfaceTransposing this to a 3 phase electrical system, where the weights are considered as 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 building 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. Then 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) and indeed sometimes it is the effect on these appliances that can be the first signal to the installers that there is a floating neutral, 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 the reason for this document, is that as a result of the increasing popularity of mobile devices that charge from a USB outlet, new/modified electrical installations may have USB chargers installed from the outset, eg: 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 such a piece of sensitive equipment and it MUST NOT be connected to an untested electrical supply

 

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 it 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
