LED Strip Power Supplies

A few recommendations regarding the choice of power supply for powering LED strips. A brief overview of several of the most popular power supplies for powering LED lighting.

Lighting equipment in our time has a large assortment. Currently, the buyer is presented with many modern developments in the field of lighting equipment, in particular LED lighting (LED strips, lamps, lamps). If you decide to use in the design of your apartment led stripthen you should know some features.

One of the features is that you cannot directly connect an LED strip to the network, such as a conventional incandescent lamp or housekeeper. This is due to the fact that the operating voltage of the LED strip is much lower than the voltage of the household network, as a rule, it is 12 V. What to do in this case? That is, how to connect an LED strip in a residential apartment network?

For this purpose, there are special power supplies that lower the voltage of the household network (220 V) to the value we need.

Which power supply to choose? First of all, you need to focus on the nominal data of the LED strip that you plan to connect. In this case, we need to pay attention to the rated voltage and power consumption.

The rated voltage, as mentioned above, is 12 V, and the rated power consumption of this type of lighting equipment is different. The amount of power consumed is directly proportional to the number and power of the LEDs located on the LED strip. Depending on this, the rated power of one meter of a particular LED strip is indicated. That is, for the right choice of power supply, you need to multiply the rated power of one meter of the purchased LED strip by its total length.

In addition, if you plan to mount the LED strip in a room that is characterized by an increased level of humidity, then pay attention to the degree of protection of the power supply housing from the negative effects of moisture.

In this article, we will briefly review several of the most popular power supplies (transformers for LED lighting) from various manufacturers.

We start our review with power supply DR-75W manufactured by Brille.

The main characteristics of this device:

• input voltage 110-120 / 220-240 V;

• output voltage 12 V;

• degree of protection of the case from the negative effects of moisture and foreign objects - IP 20;

• output power 75 W;

• rated secondary current 6 A;

• overall dimensions 159/98/38 mm.

Thepower supply is designed for power led strip and fixtures. Due to its small size, it can be mounted almost everywhere.

The power supply is connected to the household network and to the LED strip by connecting the conductors to the corresponding terminals.

The main advantages of this power supply:

• strong case from aluminum;

• small overall dimensions;

• the ability to work in several voltage ranges of a household network;

• the presence of an installed device for protection against overload and short circuit;

• ease of connection;

• warranty service for one year;

• long service life.

Considera Brille power supply unit of slightly lower power type DR-15W, which is suitable for powering a small portion of an LED strip or LED lamp.

Distinctive features of this type of power supply:

• rated output power - 15 W (rated current 1.27 A);

• rated operating voltage of 170-250 V;

• degree of protection IP67;

• overall dimensions 160/30/20 mm.

Among the advantages of this type of power supply, a high degree of protection of the power supply housing against moisture and dust should be highlighted. This characteristic feature allows you to use this power supply in rooms that are characterized by a high level of humidity.

If you need to purchase a power supply for connecting a point LED lamp or a low-power LED strip (up to 10 W), then you can purchase one of the most popular power supplies Electronic Light CS 31350M. This power supply is characterized by small overall dimensions and ease of connection.

The main advantage of this power supply is the ability to work in a wide range of both input (from 110 to 240 V) and output voltages. The output voltage range from 3 to 32 V allows you to connect this power supply to power various types of LED lighting devices.
