Voltage drop or ‘volt drop’ happens in all types of electrical installations. When larger power cables are being installed more complex calculations should be made to counteract the problem. However, when LED power supply or tapes are concerned there are a few simple guidelines to follow.
Volt drop in LED strips happens when the LEDs are positioned too much away from the source of energy or when longer individual runs (or lines) are attempted. This occurs because not enough power or electrical current reaches the LEDs, because it has further to travel. This will cause the voltage to decline or drop towards the end from the run.
Voltage drops out approximately .6V every metre and it is less noticeable with 24V strips. When using 12V strips, a 2-3V drop more than a 5 metre run would lessen the voltage by 25% subsequently decreasing the lumen (brightness) by a similar percentage.
Volt drop might be in comparison to a person climbing a mountain, the larger the altitude, the thinner the oxygen becomes and also the minus the person can breathe.
The LEDs at the beginning of the fishing line can look bright at 100% output however the LEDs towards the end of the line will quickly fade. The brightness will reduce exponentially; the further away it gets away from the power source. Potentially the sunshine output might be reduced to % if greater distances were incorrectly attempted and cause permanent harm to the LEDs.
Volt drop in single colour strips are barley noticeable, particularly in shorter lengths. Colour changing strips are more visible whenever you turn the color to white. If you have not enough voltage right at the end in the strip the clear white colour will turn pink right at the end in the line. It is because white colour is mixed from red, green and blue (RGB). However, the red requires less voltage than green and blue. If the strip is significantly through the power supply, green and blue don’t get enough voltage and be weaker, whilst the red colour grows more prominent and turns white into pink.
The higher the wattage from the LED strip, the short the run should be. For example; 30 LED (7.2W) per metre strip can have a maximum run of 10 metres, when compared to the 60 LED (14.4W) per metre strip which could have a maximum run of 5 metres.
This does not necessarily mean you can’t install longer runs of LED strip, it simply means that you should require a different approach. Single colour strips and colour changing (referred to as RGB) strips are not the same because colour changing LEDA driver 12v need to be controlled from a single controller. Utilizing a higher rated power source will not fix the problem since the current still has to move via a long collection of LEDs and resistors, every one draining small quantities of power.
Single colour strips ought to be wired directly back to the power supply in 5 metre of 10 metre runs depending on the version of strip i.e. 30 or 60 LED that is used. Each run is going to be powered straight from the power supply and will be excited or off by switching a switch or unplugging it through the mains. The ability supply is usually wired to some light switch but could be controlled by various types of controllers. The strips are able to be positioned however, you like, in one long line or in a rectangle shape for instance. When the strips are positioned alongside one another the lighting can look seamless, like a fluorescent tube. The run could be over 100 metres hapmys length provided that the energy supply was rated appropriately.
Volt drop will occur slightly inside the connecting power cables but since there are no LEDs or resisters etc draining the present, the volt drop will be barley noticeable. Thicker cables could be used to reach further distances.
For extended runs of colour changing strip, you need to fit amplifiers every 5 or 10 metres. Amplifiers allow the strips to get powered indirectly from the power supply but additionally allow the signal from your controller to move from the entire run of strips. This way once you turn the color to red as an example, everything turns to red at the same time. The amplifiers power the strip, the power supply powers the amplifiers. Amplifiers can even be powered from their own separate power supply and you can have as many power supplies as you like on the same run. The power supplies can be positioned closer to the LED strip connection or wherever is most accessible.
For prolonged, more difficult runs we are able to supply our customers making use of their own simple to follow wiring diagram. The diagram illustrates how the power source, strips and cables are connected together. As part for your LED Strip Fit brand, LED Constant voltage drivers can be supplied to the exact lengths required; everything in addition to the larger hard wired power supplies may be plugged into each, requiring no tools or electrical knowledge.
