The VSP is specially designed for stabilizing supply voltages. These are of course safe to use but you can read the text about the heat carefully. Voltage regulators reduce the voltage and, in exchange, he converts that energy into heat. Make a good estimate of your consumption and, if desired, use heat sinks to dissipate the burned heat.
The prints are suitable for a capacity of 1 maximum Ampère and the voltage regulators may have a temperature of a maximum of 125 degrees. In addition, the controllers switch themselves off.
