Speaker Protection Board DIY kit Need to Solder
The speaker protection board has the power delay (3 seconds) and DC protection (from the control voltage is about 1V) function, a simple circuit board, making easy, safe and reliable. With LED status display, when the protection light, the normal work time off. using 15A high current relay, suitable for the vast majority of amplifier board. Operating voltage AC 12-15V, requires a separate power supply. After installation size: length 65mm x width 40mmx high 25mm
- BTL circuit need two sets.
- DIY kit onlyyou need to weld the components and board by yourself(instruction will be attached).
- Note: DIY kit installation requires some basic electronic production and practical ability, there is the risk of damage during the process of installing, once the parts are installed we are not responsible for the components. thank you for your understanding.
