LED strips are quite common today. They are ideal for lighting rooms. Also their advantage is that they can be installed in any form. Nowadays, models of various capacities are presented on the market. In order to determine the connection of tapes to the 220 V network, you need to familiarize yourself with the main types, as well as disassemble the most common schemes.
Using step-down 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 a parallel connection type. However, a serial connection to the lowering unit is also possible. If we consider the first option, then the controllers are more appropriate to select low resistance. In this case, the threshold voltage can be expected at 20 V. Directly connecting the LED color tape to the distribution panel occurs in the first phase. At the same time, adapters are rarely used in such circuits. If we consider the serial connection of tapes, then it is necessary to provide a block in the circuit with a throughput of at least 2 microns. All this ultimately avoids a short circuit.
Using electrode power supplies
Connecting tapes with an electrode power supply can only be done in parallel. In this case, the controllers are low impedance. They are usually installed in conjunction with adapters. Direct connection to 220 LED strips is carried out in the first phase. Before 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 noted that in some situations the use of amplifiers is allowed. It makes sense to install them if the transmittance of the electrode block is less than 3 microns. In this case, the negative resistance of the circuit can change dramatically. Thus, the LED strip will not work for a long time.
Connection with operational power supply
With the operating unit, connecting the LED strip to the 220V network (the diagram is shown below) is quite simple, but keep in mind that in this case there are two connection options. If we consider the parallel type, then the unit is more appropriate to install with a multi-channel controller. In this case, it is more expedient to connect amplifiers only of a resonant type. In some situations, absorbing filters may be installed. For a 220 V network, they must withstand resistance of at least 30 Ohms. Saturation filters, in turn, are absolutely unsuitable 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 distribution panel through the unit, then the amplifier in this case is important to use with an adapter. All this will allow to stabilize the threshold voltage parameter in the electric circuit.
Connecting LED strips to the battery
Connecting LED strip to the battery, as a rule, is carried out through terminal blocks. In this case, the connection can occur both in serial and parallel form. In this case, filters are rarely used. However, the 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 control the power of the LED strip, different types of controllers are used. Today, multichannel 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 protect LED strips from overloads. In this case, energy from the battery will be spent economically.
Features of connecting the R series tapes with the remote control
Connecting an LED strip with a remote control can occur only with the participation of absorbing filters. For home use, this model is ideal. At the same time, the color of the LED strip is quite different. However, they also have disadvantages. This primarily relates to low conductivity. However, regulators for LED strips are not suitable for all types. Directly connecting the model can be done through the distribution block. However, the adapter in this case will have to be used. Absorbing filters, in turn, are installed in rare cases. If the jumps in the electric circuit do not exceed 20 V, then there is no need for these components.
Connecting B Series tapes in a car
The LED strip in the car is connected to 15 V batteries. In this case, the connection occurs through an adapter. In this case, the contacts close in the first phase. Directly regulating the power of the LED strip is due to the controller. To date, the most common are considered multi-channel modifications. However, if we consider LED stripes at 5 V, then simple controllers are suitable, which can be purchased quite cheaply on the market. Many experts in this case, filters recommend installing only the saturating type. In this case, amplifiers are used quite often. If we consider the serial connection diagram of the LED strip, it is important to pay attention to membrane amplifiers. On average, they are able to withstand threshold voltage at a level of 20 V. At the same time, surges in the network are allowed to a maximum of 5 V. Membrane amplifiers are used, usually with zener diodes.
RGB tapes in a car
The LED strip in the car is connected, usually through a 20 V battery. In this case, the most diverse adapters are used. However, the regulators should be selected for this model only multichannel type. Thus, 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 stay on 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 an LED strip of this type, 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 broadband converters.
Connecting CW Tapes (12V)
For cars, a 12-volt LED strip is well suited. It can be connected only through two-phase batteries. In apartments, these models can also be used. However, in this case it is necessary to use an absorbing filter. Just before connecting the contacts, it is important to check the grounding in the unit. You can do this simply by touching the cover cap with a tester. If the resistance parameter exceeds 10 ohms, then the circuit is not closed. In this case, the LED strip can not be used.
Connection to transformer PP20
The transformer is connected to the LED strip mainly through step-down power supplies. It is important to select them only with passage thyristors. At the first stage, the contacts on the controller are cleaned. It is important to consider 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 primarily to do 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 ohms.
Using transformers PP21
Through the transformer PP21, 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 option is considered to be 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 sequential circuit, then it is more expedient to install a multi-channel type. In the parallel version, you can consider a single-channel analog. The regulator is mounted directly in the system behind the adapter. To increase pore voltage, many experts recommend the use of magnetic filters. However, in such a situation, the load parameter on the electric circuit should not exceed 10 A.
Application of transformers PP30
Through a transformer of this type, the connection of the LED strip to the 220V network (the diagram is shown below) can be carried out only with a phase adapter. For connection, conductors with conductivity of at least 2 microns are used, as a rule. Directly 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. In addition, it is important to pay attention to the threshold voltage parameter. On average, it fluctuates around 22 V. However, in this situation, the load can exceed 5 A. In this case, the LED strip quickly burn out. To correct this situation, many experts recommend the use of absorption filters. They should be installed directly on the controller blocks.
Operational type controller connection
Through an operating-type controller, connecting an LED strip to a 220V network (the diagram is shown below) is quite simple. In this case, the adapters must be installed with a phase frequency of 20 Hz. In this case, the negative resistance in the circuit should be checked using a tester. If we consider LED lamps at 5 V, then amplifiers in this case are not required for connection. In turn, modifications to 10 V require the use of 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 operating type controllers are installed behind the filter. With a parallel connection of contacts for an electric circuit, two are required. Otherwise, the negative resistance parameter will be more than 3 ohms. In this situation, LED lamps will not be able to work for a long time.
Coaxial Ribbon Controllers
Connecting tapes through coaxial controllers can be found quite rarely. For houses, these schemes are not suitable. In this case, the power supply will be required at 30 V. It should also be borne in mind that modulators are not installed in such situations. However, if we consider the serial connection, then single-channel modifications can still be used. A distinctive feature of this type of controller is the increased frequency. In this case, they are able to withstand peak voltage at a maximum of 20 V. The load on the electrical circuit is allowed at 40 A.
