LED strips are quite common today. They are perfect for room lighting. Also, their advantage is that they can be installed in any form. Nowadays, there are models of various capacities on the market. In order to decide on the connection of tapes to a 220 V network, you need to familiarize yourself with the main types, as well as analyze the most common schemes.
Using buck power supplies
Connecting a 220 volt LED strip through a step-down power supply is quite simple. In this case, models of various frequencies. The most common is the parallel type of connection. However, a series connection with a buck block is also possible. If we consider the first option, then it is more expedient to select low-resistance controllers. In this case, the threshold voltage can be expected to be 20 V. The direct connection of the LED colored strip to the switchboard occurs in the first phase. Whereinadapters in such circuits are used quite rarely. If we consider the serial connection of tapes, then it is necessary to provide a block with a bandwidth of at least 2 microns in the circuit. All this will ultimately avoid a short circuit.
Using electrode power supplies
Tapes with electrode power supply can only be connected in parallel. In this case, low-resistance controllers are used. They are usually installed in pairs with adapters. Direct connection to the 220 LED strip is carried out in the first phase. Before doing this, it is important to check the grounding of the distribution block. In this case, you can easily determine the phase using a tester. It should also be borne in mind that in some situations the use of amplifiers is allowed. It makes sense to install them if the transmission capacity of the electrode block is less than 3 microns. In this case, the negative resistance of the circuit can change dramatically. Therefore, the LED strip will not work for a long time.
Connection with operating power supply
With an operating unit, connecting an LED strip to a 220V network (the diagram is shown below) is quite simple, however, it should be borne in mind that in this case there are two connection options. If we consider the parallel type, then it is more expedient to install the unit with a multi-channel controller. In this case, it is more expedient to connect amplifiers only of the resonant type. In some situations, the installation of absorbing filters is allowed. For a network of 220 V, they must withstand a maximum resistance of at least 30 ohms. Saturating filters, in turn, are absolutely not suitable for such circuits. This is largely due to large wave fluctuations in the network. If we consider the serial connection of the LED strip to the switchboard through the block, then in this case it is important to use the amplifier with an adapter. All this will allow to stabilize the threshold voltage parameter in the electrical circuit.
Connecting LED strips to the battery
Connecting the LED strip to the battery, as a rule, is carried out through terminal blocks. In this case, the connection can occur both in series and in parallel. In this case, filters are rarely used. However, adapters need to be installed, and they are most suitable for the magnetic type. To connect an absorbing filter, you will have to use a modulator. To be able to adjust the power of the LED strip, different types of controllers are used. Today, multi-channel models are in great demand among motorists. You can find them in the store with regulators of various shapes. In this case, it is necessary to pay attention to their conductivity. On average, this parameter fluctuates around 3 microns. However, there are better models that will save LED strips from overload. In this case, the energy from the battery will be spent economically.
Features of connecting R series tapes with remote control
Connecting the LED strip withremote control can only occur with the participation of absorbing filters. For home use, this model is ideal. At the same time, the color of the LED strips is quite different. However, they also have disadvantages. First of all, this concerns low conductivity. At the same time, regulators for LED strips are not suitable for all types. Direct connection of the model can be carried out through the distribution block. However, in this case, an adapter will have to be used. Absorbing filters, in turn, are installed in rare cases. If the surges in the electrical circuit do not exceed 20 V, then there is no need for these components.
Connecting B series tapes in the car
The LED strip in the car is connected to 15 V batteries. In this case, the connection is made through an adapter. In this case, the contacts are closed in the first phase. Direct regulation of the power of the LED strip occurs due to the controller. To date, the most common is considered to be multi-channel modifications. However, if we consider 5 V LED strips, then simple controllers that can be purchased quite cheaply on the market are also suitable. In this case, many experts recommend installing filters only of a saturating type. In this case, amplifiers are used quite often. If we consider the serial connection of the LED strip, then it is important to pay attention to membrane amplifiers. On average, they are able to withstand the threshold voltage at a level of 20 V.. At the same time, surges in the network are maximumallowed up to 5 V. Membrane amplifiers are used, usually with zener diodes.
RGB strips in car
The LED strip is connected in the car, usually through a 20 V battery. In this case, a wide variety of adapters are used. However, regulators should be selected for the indicated model only of the multi-channel type. In this way, battery wear can be significantly reduced. Amplifiers for this circuit are suitable for both membrane and integral types. If we consider the parallel connection of the LED strip, then it is better to stop at the first option. In this situation, the threshold resistance parameter in the circuit usually does not exceed 20 ohms. All this suggests that the load on the battery is not large. If we consider the serial connection of this type of LED strip, then the amplifiers are usually installed integrated. All this is necessary to increase the phase voltage parameter. However, this effect can also be achieved through the use of wideband converters.
Connecting CW tapes (12 V)
12 Volt LED strip is well suited for cars. It can only be connected via two-phase batteries. In apartments, these models can also be used. However, in this case, you will have to use an absorbing filter. Immediately before connecting the contacts, it is important to check the grounding in the block. You can do this simply by touching the testerto the top of the lid. If the resistance parameter exceeds 10 ohms, then the circuit is not closed. In this case, LED strips cannot be used.
Connection to PP20 transformer
The transformer is connected to the LED strip mainly through step-down power supplies. It is important to select them only with through-thyristors. At the first stage, the contacts on the controller are cleaned. It is important to take into account its type. If we consider operational modifications, then in this case the terminal blocks are usually used with a damper. In such a situation, many experts advise first of all to deal with the grounding system. After connecting the LED strip in the circuit, it is necessary to check the threshold resistance. When connected in series, the specified parameter must be at least 30 Ohm.
Using PP21 transformers
Through the PP21 transformer, the connection of the LED strip to the 220V network (the diagram is shown below) can be carried out in various ways. The most common is considered to be the option with a phase amplifier. It is connected, as a rule, through a wave filter. A controller is used to adjust the peak voltage on the LED strip. If we consider the option with a serial circuit, then it is more expedient to install a multi-channel type. With a parallel option, you can consider a single-channel analogue. The regulator itself is mounted in the system behind the adapter. To increase the pore stress, muchexperts recommend using magnetic filters. However, in such a situation, the load parameter on the electrical circuit should not exceed 10 A.
Use of PP30 transformers
Through a transformer of this type, the connection of an LED strip to a 220V network (the diagram is shown below) can only be carried out with a phase adapter. For connection, as a rule, conductors with a conductivity of at least 2 microns are used. Direct controllers in this situation can only be installed single-channel type. At the same time, they should have regulators with a peak frequency of 30 Hz. Additionally, it is important to pay attention to the threshold voltage parameter. On average, it fluctuates around 22 V. However, in this situation, the load may exceed 5 A. In this case, the LED strips quickly burn out. To remedy this situation, many experts recommend the use of absorbing filters. They should be installed directly on the controller units.
Connection of Operation Type Controller
Through an operational type controller, connecting an LED strip to a 220V network (the diagram is shown below) is quite simple. In this case, adapters must be installed with a phase frequency of 20 Hz. In this case, the negative resistance in the circuit should be checked with a tester. If we consider 5 V LED lamps, then amplifiers in this case are not required for connection. In myturn modifications to 10 V need to use broadband devices to increase the peak voltage parameter. If we consider the serial connection of the LED strip, an adapter is needed to connect the device to the distribution block. In this case, the controllers of the operational type are installed behind the filter. With a parallel connection of contacts for an electrical circuit, two will be required. Otherwise, the negative resistance parameter will be more than 3 ohms. In such a situation, LED lamps will not be able to work for a long time.
Coaxial Tape Controllers
Connecting tapes through coaxial controllers is quite rare. For houses, these schemes are not suitable. In this case, a 30 V power supply will be required. It should also be borne in mind that modulators are not installed in such situations. However, if we consider a serial connection, then single-channel modifications can still be used. A distinctive feature of this type of controllers can be called an increased frequency. At the same time, they are able to withstand a maximum voltage of 20 V. The load on the electrical circuit is allowed at 40 A.
