demand for light, the intensity of which you can regulate, there is not only among the professional use of lighting, but also in everyday life, when you can control the brightness of the source, regardless of the level of light in the room.Today we talk about how to choose the dimmer - a device that not only ignites, but also allows you to control the brightness - from the blinding radiance to the intimate lighting.

At arrangement of lighting in the home is often necessary not only to turn on and off light sources, but also changes in its brightness.And this goal is not achieved by a conventional switch.We need a special device that allows you to control the level of brightness in the room.
The most common name for devices that allow you to adjust the voltage at the l
dimmer pack can be made structurally wall mounted (for stationary applications), rack mount housing (for installation into a rack) and suspended body (for location near the light sources).Rack unit usually consists of 12 channels at rated load 2.5 kW per channel, wall-mounted unit has a 12-24 channel approximately 1-3 kW outboard block contains four channel output 1-3 kW.
standard dimmer control
dimmer pack in terms of governance can be divided into 3 types: digital, analog, and digital-to-analog.Control signals in analog dimming blocks performs constant voltage which ranges from 0 to 10 V. Depending on the magnitude of the voltage to be regulated voltage at the load.The control signal in this case comes from the remote control.
Digital dimmer blocks represent a more modern and professional dimmers.The control signal is a digital sequence.DMX512 control protocol can transmit data about the state of channels 512, each having about 256 brightness gradations.The basis of the digital dimmer pack - a microprocessor, which is a particular algorithm converts the digital information into a signal triac control.
Digital-to-analog blocks are in essence a combination of digital-to-analog converter and analog dimming.Such an approach, in spite of the complicated circuitry allows the power unit to make a universal, which is dependent on the control signal is capable of operating as an analog or digital dimmer.
Currently, digital dimmers being squeezed out of the market and other instruments.The processor allows you to make the machine is in svitcherny mode when the channel has only two states - on / off, and sets the threshold by the user, control the temperature, counting operating time, voltage regulation.If there is even the slightest possibility, should go to the global standard DMX512.
dimmer for the different lamp
Dimmers are universal, that is intended by any lamp, and special - for example, for low-voltage halogen lamp bulbs nakalyvaniya such as dimmers makel.Dimmers for different lamps have different internal structures.Dimmers for incandescent lamps rated at 220 volts.The filament bulb is heated, and then the light brighter or less, depending on the voltage supplied through the regulator to her.
are commercially available dimmers A low-voltage halogen lamps which are powered by a transformers.If your housing mounted lamps that are designed to supply voltage to 12-24 volts, then you will also need a transformer that is capable of converting the output voltage of the dimmer to a value which is within the 12-24 volts.
Dimmers for LED and fluorescent lamps need a special, non-standard, such as dimmers ABB.For operation with dimmers fluorescent lamps in the luminaire requires electronic ballasts.Since its release Start-regulating equipment lamp with dimmer transmits voltage between 0 - 10V and regulates such intensity gas discharge means, in other words - the power of light.
Summing up, note that when you select the dimmer it must relate to the type and capacity of lamps that are available in your home.If you do not want all these technical details to deepen, better to buy a universal dimmer.
Pushbutton dimmers are divided into rotary and push.Rotary dimmers are the simplest kind of dimmers.Lighting ignited by turning the knob, button, and the light is regulated by its rotation, and the disconnection occurs in an extreme position - when clicks.Rotary dimmers are suitable for any premises that do not require the same level of illumination when you turn on the device.An example of this can serve as a dimmer dimmer ABB, designed for fluorescent lamps.
In the second case, using the push dimmer lights on by pressing the button while rotating it changes the light intensity.When you turn off the light unit memorizes the brightness level that is set before it, and when you turn to the start of this level.Remember the actions of users it allows them mounted microcontroller.
However, not all push-button controls have a single button.For example, Legrand Valena dimmers equipped with two buttons, one of which is intended for on-off, and the other - to adjust the brightness.Pressure dimmers designed for rooms that do not need to change the light level at each inclusion of light.User once exposes the desired light level and then uses the only option on-off without adjusting the brightness.
fashionable and convenient solution is LED and touch dimmer.They are controlled by a light touch to the surface of the lamp or panel Touch Pad.So turn on or turn off the lights.If you hold your finger on the sensor, the light will grow gradually, and after reaching the maximum will decrease.The outer cover of the dramatic dimming backlit to create an original and respectability in the interior.
Keyboard dimmers similar to traditional switches, push dimmers but perfect.Pressing the button turns on and off the light, and the brightness can be controlled by holding the key in the active state for more than 3 seconds.
Indicators power dimmer
It is the most famous characteristic of the dimmer.To choose the right tool, you should know the total load, it can withstand.For example, the figure is 300 W, which is indicated on the dimmer, it said that with his help, you can change the brightness of the light 5-Rozhkova chandeliers with light bulbs, each 60 watts.But just in case, take a dimmer switch with power reserve.
Admissible power, which accounts for the channel device, is often actually less than is written in the passport dimmer.And it is not always associated with unscrupulous manufacturers.It triggered an indicator such as the load factor.For instance, the dimmer channel 4, 2.5 kW each, the load factor is 75%.Thus, at any time can operate at full power only 3 channels, or they can all be included at 75% power.So well, if you get the hang of the canal about 30-50% less load than indicated in the passport.
no less important characteristic appears dimmer a minimum load capacity.Not everyone will be able to control the dimmer light bulb 40 W, although such problems to be addressed often enough.By the way, confident in the small load is considered to be confirmation of the quality of the applied power of the device and the correct circuit solutions.
also when choosing the dimmer is to make sure that he is able to infinitely adjust the time stated power without overheating.Otherwise, the actual load, which you connect to it without fear, will be less than expected.Furthermore, the higher load factor, the dimmer design safer and less risk of the remote control of the dimmer system.
If you are planning to use a dimmer in hard temperature conditions with a large load factor, you should ask if they have active ventilation of the device (in other words - the fan).With other things being equal, active ventilation system facilitates the work of the dimmer.The intensity of the fan in the most advanced designs of dimmers depends on the temperature, which is supported within the housing.
Dimmer is a energonagruzhennym device.Each channel provides power to a load of several kilowatts.Therefore, such a device must be equipped with the proper safety equipment, the main element of which is the circuit breaker (AB).When congestion occurs, and there is a danger of overheating and melting wiring, AV switches off the alarm line.
must now talk about the basic elements of the dimmer.At the time of purchase you are unlikely to look inside the device, but verify the functionality you still will be able to draw some conclusions.Pay attention to the type of dimmer - looks neater than the unit, the more you can trust him.Then check the breakers channels.Well, if there are machines, connectors, sockets to the dimmer from Legrand.
Look how the dimmer during fluctuations in voltage at the load.If you have noted the changing unit dimmer buzz when you change the brightness level, the phone has a throttle, which is good.If you could look inside, remember that the power wires should not be less than 1.5 square meters.Introductory - not less than 6 square meters.Otherwise it may leak when fully loaded insulation, and the dimmer will not function.
If the wires tied into bundles, it testifies to the general accuracy.Boards should have a blue or green color.This means that used strong paint that is able to further protect the elements and charge against moisture and mechanical influences.If you see a double-sided board, then protection must be on both sides.
Fan bearings should be as similar to fan six months starts to creak.Radiator must not be less than 100 square \ cm by 1 power element otherwise be dimmer load of 2 kW is similar to the oven.
bad if dimmer Agate is possible to stabilize the voltage.Stabilizing factor is defined as the change in output voltage dimmer when changing the mains voltage.The presence of the stabilizer is necessary, if the network always "jumps" voltage, and emissions in our lines often reach 240 or 250 V. The regulator, in this case does not allow to submit more than 220 volts to the load.
On the other hand stabilization does not allow light to blink (fade) with voltage dips in the mains, which are caused by a thin conductive cable, uneven loading of the phases and other problems that are related to the quality of the input power dimmer.
Calculate the relative value of the dimmer is simple.The cost of the unit should be divided by the number of channels on one channel power.Choosing the best option is recommended.Difficult to another: it is almost impossible to produce quality and cheap dimmer.For example, if you offer a new 12-channel dimmer DMX512 5 kW per channel for 10 thousand rubles, you need to think about why it is so cheap.
Remember that in such a dimmer chokes will not be exact, the radiator will be weak, triacs will function at the limit, and certainly can not dream of a convenient interface.Dimmers on high-quality components are expensive.For example, the difference between the Legrand dimmer and PLASTEX for one channel is close to 300 rubles.Imagine if the dimmer has 12 channels, the price difference is impressive.
with throttle the difference in cost will be even more difficult to make a qualitative choke less than 350 rubles, if to put branded components, then its price will start at $ 25.The difference in the symistors can often be 200 rubles.In the end, it turns out that high-quality 12-channel dimmer can cost from 10 to 30 thousand rubles and more.
So you realized that the choice of dimmer - not an easy task.You must pay attention to the appearance and orderly assembly or dimmer viko legrand, learn more about the components and their quality.With special care to analyze the indicators Treat power dimmer, since these coefficients depend on the time machine.
