Andowl LED power supply with an output voltage of 12V DC. The appropriate power supply for an LED strip is calculated by multiplying its consumption in Watts per meter by its length. It is recommended, however, to obtain a power supply that supports 20% more than the required energy, in order not to work at its limits. In this case, the power supply of the product is 500 Watts, which means it has the capability to power, for example, a 5-meter LED strip with a power consumption of 80 Watts per meter.
