Does the VaLO RF transformer have a memory, i.e. if the power goes out does it remember what it was set to? ❯
Yes, it is! Often better than the user... This has been tested on summer cottages where the power can be off for 3-4 months at a time and the memory is fine.
How long is the connecting wire between the 12V or 24V transformer and the luminaire? ❯
24V will easily last 15-20m with a normal 0,75mm3 cable. 12V products will drop voltage half as fast.
Which VaLO RF transformer? ❯
Wireless control of lighting. The control of light temperature and dimming can be fully wirelessly controlled. The transformer only needs a constant supply of electricity (you can get it from the back of a microwave) and the control is done with wireless buttons.
Where to place the transformer? ❯
For example, in kitchens, when doing countertop lighting, the transformer can be installed on top of a cabinet, on a top shelf or behind a plinth. A wirelessly controlled transformer can be plugged in behind a microwave, on top of a fridge or even in a cooker hood cabinet. In rooms, the transformer is usually installed behind a service hatch or, if there are panel lights in the room, they can also be used as hatches. For transformers to be placed outdoors, an adequate IP rating should be considered.
How to calculate the transformer size? What does 100W mean in practice? ❯
The size of the transformer is calculated by multiplying the metric consumption of the led strip by the length used for the installation, then multiplying by 1.1 or 1.15 to give a margin of 10-15%.
For example, 100W, or 100 Watts, means the transformer has a total load capacity of 100W.
If an LED strip with a power of 14.4W/metre is installed in the transformer, that 100W transformer will withstand 6.3 metres of LED strip with a 10% margin.
Can I install several different led strips on the same transformer? ❯
Yes you can. The led strips are all installed in parallel (i.e. colour by colour) with the pluses in their own bundle and the minuses in their own bundle. You can do this, even with a sugar cube or a Waco connector.
Please note that the transformer will still have a sufficient total load capacity.
What is the difference between a 12V and a 24V transformer? ❯
12V is a 12 volt system and 24V is 24 volts. These should not be confused. 24V LED products work more reliably because the voltage does not drop as quickly over long distances.
What happens if I put a 12V led strip into a 24V transformer or vice versa? ❯
12V led strip in a 24V transformer supplies too much voltage to the led strip and it gets too hot and burns out quickly. the 24V ribbon on the other hand will not even turn on with a 12V power supply.
How long can I put a 12 or 24V transformer before the lamp? ❯
24V will easily last 15-20m with a normal 0,75mm3 cable. 12V voltage drops half as fast.
What is a TRIAC dimmable transformer? ❯
TRIAC is a traditional primary (230V) dimming technology. In practice, it is a rotating knob on the wall that adjusts the ballast, i.e. dims the light behind it. Like incandescent lamps.
What can be used to dim TRIAC dimmable transformers? ❯
VaLO with 230V wireless dimmers and traditional wall switches.
We test the dimmers on the market and here is a table. see https://ledstore.fi/led-himmentimet
What is DALI? ❯
DALI is an international standard where lighting is controlled by a reprogrammable system. see more: https: //www.digitalilluminationinterface.org/
In practice, a 2-pole low-current cable runs alongside the power supply to the luminaires for control.
What is an ampere? Watt? Power? ❯
Watt = Ampere / Power. That is, a 5A transformer at 24DCV can withstand 120W of power or a 120W transformer at 24V can withstand 5A.
What is the difference between 200-1500mA (milliampere) and 12/24V DC (direct current) transformers? ❯
mA control keeps the current constant but the voltage varies according to the load and dimming level. The transformer is always accurately sized in advance before installation and the load cannot be added afterwards.
With DC DC voltage, the same voltage is applied to all e.g. 24V and each luminaire draws the required amount of current (A). Dimmable Led luminaires are generally mA controlled and Led strips DC controlled.
Is it possible to control each channel of the transformer wirelessly separately? ❯
Unable to. Channels are intended for multicolour different shades. Each channel has only negative voltage. The transformer has only one positive output.
