LED lighting systems have significant impact on our lives with their energy efficiency, compactness, reliability and extended service life. Apart from home, industrial and street lighting, they also serve as an effective architectural lighting. Pulse LED power supplies are used to power single or grouped power LEDs that require a stable output current. Regardless of the input voltage fluctuations, the output parameters do not change. This quality makes them particularly suitable for settlements with unstable voltage. When choosing a power supply, you need to determine how much consumes the source, and it is advisable to add 20% of the total power of your system to ensure the proper functioning of the power supply.
