•Support DC and AC power supply
•With delay and DC protection function (default 1.8V start control, DC sensitivity can be adjusted)
•This common power supply DC protection board uses optocouplers. Because optocouplers are isolated from each other between input and output,
•This protection board uses 1.6 thick 1A copper surface, double-sided tin plating process, and the input voltage is DC 12V-16V or AC 12-16V
•The power supply can be the same as the power amplifier. The negative pole of the three-channel audio source is independent. It is suitable for non-common ground and BTL circuit power amplifiers: the terminal is 7.62 pitch, and the 1/2W metal film exceeds the standard using internal resistance. The reduction is designed for high current!
