Dimmable LED power supply by Adeleq with an output voltage of 21-53V DC. The appropriate power supply for an LED strip is calculated by multiplying its consumption in Watts per meter by its length. However, it is recommended to purchase a power supply that supports 20% in addition to the required energy, so that it does not work at its limits. In this case, the power supply of the product is 12 Watts, which means that it has the ability to power, for example, a 5-meter LED strip with a power consumption of 1.6 Watts per meter.
