The power supply unit plays an integral and important role in lighting with LED strips. It serves to convert the current from the mains to the appropriate voltage and power to power the LEDs. Without a proper power supply, the LED strip will not be able to work properly and perform its functions. Choosing the right power supply unit allows you to ensure stable and efficient operation of LED strips, as well as preserve their long service life.
Power calculation
Before starting to use the LED strip, it is necessary to correctly calculate the power consumption and select the appropriate power supply unit. This ensures proper operation and helps preserve the life of the LED strip.
To calculate the power of the power supply unit (Rbzh, W), you must first find the power consumption of one meter of tape (Pm, W/m). Then we multiply this value by the number of meters of tape that will be connected to the power supply unit (L, m). The next step is to multiply the received amount by the reserve factor Kz = 1.25, which provides a power reserve of 25-30%.
So, the formula for calculating the power of the power supply is as follows: Рбж = Пм × L × Кз
It is important to consider that LED strips can be connected to the power supply unit no more than 5 meters. If the length of the LED strip exceeds 5 meters, the sections longer than 5 meters must be connected to the main power line separately. This helps preserve the life of the tape and provide a more even glow.
Before connecting the LED strip to the power supply unit, make sure that the connection is made in compliance with the correct polarity. This is important to prevent possible damage and ensure the proper operation of the LED strip.
The choice of a power supply unit for a neon strip depends on the place of installation and its features. If you plan to install lighting in an office or a private house, then a regular model with a leaky housing is usually enough.
However, if the installation will be carried out in a damp room or places with high humidity, high tightness becomes a key condition. Here, it is recommended to use a powerful hermetic power supply unit with a cooler, which will ensure reliable operation in conditions of humidity and high temperatures.
For street lighting, a power supply unit with the maximum protection index is required, as it will be exposed to atmospheric conditions. When choosing the power of the power supply unit, it is important to consider what kind of lighting is planned, since different light sources can have different power requirements.
Regardless of the place of installation, it is important to follow the rules for choosing products of well-known brands that are responsible for their products. This guarantees the efficiency, reliability and safety of the entire lighting system, as well as ensures a long service life and the pleasure of working with lighting.
