Connecting LED strip to 220V network: circuit and description

LED tapes are quite common today. For indoor lighting, they fit perfectly. Also their advantage lies in the fact that they can be installed in any form. In our time, models of various capacities are represented on the market. In order to determine the connection of tapes to the 220 V network, it is necessary to familiarize yourself with the main types, and also to disassemble the most common schemes.

Use of step-down power supplies

It is possible to connect a 220 volt LED strip through the step-down power supply unit quite simply. In this case, the models have a variety of frequencies. The most common is the parallel connection type. However, a serial connection to the lowering unit is also possible. If we consider the first option, then the controllers are better to choose low-resistance ones. In this case, the threshold voltage can be expected to be 20 V. Direct connection of the LED colored tape to the switchboard takes place in the first phase. In this case, the adapters in such circuits are rarely used. If we consider the serial connection of tapes, then it is necessary to provide in the circuit a block with a throughput of at least 2 microns. All this in the long run will avoid short circuits.

Using Electrode Power Supplies

Connecting tapes with an electrode power supply can only be done in parallel. In this case, the controllers are low-resistance. They are installed, as a rule, on a pair with adapters. Direct connection to 220 LED strip is carried out on the first phase. Before doing so, it is important to check the grounding of the distribution unit. The phase in this case can be determined easily using a tester. It should also be noted that in some situations it is possible to use amplifiers. It makes sense to install them, if the transmission capacity of the electrode block is less than 3 microns. At the same time, the negative resistance of the circuit can vary dramatically. Thus, the LED tape will not work for a long time.

Connection with the operating unit power supply

With the operating unit, the connection of the LED tape to the 220V network (the circuit is shown below) is quite simple, but it should be noted that in this case there are two connection options. If we consider a parallel type, then it is more expedient to install the unit with a multichannel controller. In this case, it is more reasonable to connect amplifiers only to a resonance type. In some situations it is possible to install absorbing filters. For a network of 220 V, they have to withstand the ultimate resistance of at least 30 ohms. Satisfying filters, in turn, for such circuits are absolutely not suitable. In many respects this is due to large wave fluctuations in the network. If we consider the serial connection of the LED tape to the switchboard through the unit, then the amplifier in this case is important to use with the adapter. All this will allow stabilizing the parameter of the threshold voltage in the electrical circuit.

Connecting the LED strips to the battery

Connection of the LED strip to the battery is usually carried out through the terminals. In this connection, the connection can occur in both serial and parallel form. In this case, the filters are used quite rarely. However, the adapters need to be installed, but they are most suitable for the magnetic type. To connect an absorbing filter, you must use a modulator. To control the power of the LED strip , different types of controllers are used. To date, multi-channel models are in great demand among motorists. Find them in the store can be with regulators of various shapes. In this case, it is necessary to pay attention to their conductivity. On average, this parameter fluctuates around 3 μ. However, there are better models that will save LED strips from overloads. At the same time, energy from the battery will be used economically.

Features of connection of tapes of a series R with the panel

Connecting the LED strip with the remote control can only take place with the help of absorbing filters. For home use, this model fits perfectly. At the same time, LED stripes are quite different in color. However, they also have shortcomings. First of all, this concerns low conductivity. However, the regulators for LED tapes are not suitable for all types. The model can be directly connected via a distribution block. However, the adapter in this case will have to be used. Absorption filters are in turn installed in rare cases. If the jumps in the electrical circuit do not exceed 20 V, then there is no need for these components.

Connection of B series tapes in the car

Connection of the LED tape in the car is carried out to the batteries at 15 V. In this case, the connection is through the adapter. In this case, the contacts are closed in the first phase. Directly, the power of the LED tape is controlled by the controller. To date, the most common are the multichannel modifications. However, if we consider LED tapes at 5 V, then simple controllers, which on the market can be purchased quite cheaply, will do. Many experts in this case, the filters recommend installing only saturating type. In this case, amplifiers are used quite often. If we consider a sequential scheme for connecting an LED strip, then it is important to pay attention to the membrane amplifiers. On average, the threshold voltage they are able to withstand at 20 V .. In this case, jumps in the network maximum allowed to 5 V. Used membrane amplifiers, usually with zener diodes.

RGB tapes in the car

There is a connection of the LED tape in the car, usually through a battery of 20 V. In this case, the adapters are used the most diverse. However, regulators should be selected for the specified model only multi-channel type. Thus, the wear of the battery 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 dwell on the first option. In this situation, the threshold resistance parameter in the circuit does not usually exceed 20 ohms. All this suggests that the load on the battery is not great. If we consider the serial connection of an LED strip of this type, then the amplifiers are usually installed integral. All this is necessary to increase the phase voltage parameter. However, this effect can also be achieved through the use of broadband converters.

Connection of CW tapes (12 V)

For cars is well suited LED tape 12 volts. It can only be connected via two-phase batteries. In the apartments, these models can also be used. However, in this case it is necessary to use an absorbing filter. Immediately before connecting the contacts, it is important to check the earth in the unit. This can be done simply by touching the tester to the lid of the lid. If the resistance parameter exceeds 10 Ohm, then the circuit is not closed. In this case, LED strips can not be used.

Connection to transformer PP20

The connection of the transformer to the LED strip is mainly through lowering power supplies. Select them is important only with thyristors. At the first stage, contacts on the controller are cleaned. It is important to consider its type. If we consider operational modifications, then in this case the terminals are usually used with a damper. In this situation, many experts advise first of all to take up the grounding system. After connecting the LED strip in the circuit, it is necessary to check the threshold resistance. When connected in series, this parameter must be at least 30 ohms.

Use of PP21 transformers

Through the PP21 transformer, the connection of the LED tape to the 220V network (the circuit is shown below) can be performed in various ways. The most common is considered to be a version with a phase amplifier. It is connected, as a rule, through a wave filter. The controller is used to adjust the peak voltage on the LED strip. If we consider a variant with a sequential circuit, then it is more reasonable to install a multichannel type. In the case of a parallel variant, one-channel analogue can be considered. Directly the regulator is mounted in the system behind the adapter. To increase the pore voltage, many experts recommend using magnetic filters. However, in such a situation, the load parameter on the electric circuit should not exceed 10 A.

Application of PP30 transformers

Through a transformer of this type, the connection of the LED strip to the 220 V network (the circuit is shown below) can only be carried out with a phase adapter. As a rule, conductors with a conductivity of at least 2 microns are used for the connection. Directly controllers in this situation can be installed only one-channel type. In this case, the regulators must have 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, LED strips quickly burn out. To correct this situation, many experts recommend using absorbing filters. Install them directly on the controllers.

Connecting the controller of the operating type

Through the operating-type controller, connecting the LED tape to the 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 with a tester. If we consider LED lamps at 5 V, then amplifiers in this case are not required for connection. In turn, modifications of 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 the parallel connection of the contacts for the electrical circuit, two are required. Otherwise, the negative resistance parameter is more than 3 ohms. In this situation, LED lamps can not work for a long time.

Coaxial controllers for tapes

Connecting tapes through coaxial controllers can be found quite rarely. For houses, these schemes are not suitable. In this case, the power supply is required at 30 V. It should also be noted 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 controllers of this type can be called increased frequency. With this peak voltage they are able to withstand a maximum of 20 V. The load on the electrical circuit is allowed in 40 A.
