The product in the 12V power supply can output 10W +10 W power, the chip without heat sink, but also has overheating, over current protection. This module has a switch function, the SW will be shorted to close the function output. The output part of the LC low-pass filter circuit, effectively suppress the signal line of high-frequency noise and spike interference, greatly enhanced the circuit’s anti-jamming capability, some sources of interference (such as mobile phones) near the power amplifier board will not have any interference.(The pop noise of this product is big also at power on/off. But this product provides the mute function.)
