LED power supply by V-TAC with output voltage 12V DC. The appropriate power supply for an LED strip is calculated by multiplying its consumption in Watt per meter with its length. However, it is recommended to purchase a power supply that supports an additional 20% of the required energy in order not to work at its limits. In this case, the power supply of the product is 42 Watt, which means it has the ability to power, for example, a 5-meter LED strip with power consumption of 6.4 Watt per meter. It has an IP44 protection rating, which means that solid objects larger than one millimeter cannot penetrate it, nor can water with high intensity.
