 "Speaker Protection Board Component Audio Amplifier DIY Boot Delay DC Protect Kit"
The speaker protection board has a power-on delay (about 3 seconds) and DC protection (from about 1V control) function, the board circuit is simple, easy to make, work safe and reliable. With LED status display, protection time, normal work When the use of 15A high current relay, suitable for the vast majority of the power amplifier board. Working voltage AC 12-15V, the need for independent power supply.
