bselectronics LED power supply with 12V DC output voltage. The appropriate power supply for an LED strip is calculated by multiplying its consumption in Watts per meter by its length. But it is recommended to get a power supply that supports 20% in addition to the required energy, in order not to work at its limits. In this case the power supply of the product is 24 Watt, which means that it has the ability to supply, for example, a 5 meter LED strip with a power consumption of 3.2 Watt per meter.
