Feature
1.With delay and DC protection
2.This common power DC protection board uses an optocoupler. Since the optocoupler has input and output isolation from each other,
3.The electrical signal transmission has the characteristics of unidirectionality, and thus has good electrical insulation capability and anti-interference ability.
4.Moreover, since the input end of the optocoupler belongs to the low-resistance type of the current type operation, it has a strong common mode suppression capability, and the power source and the sound source are separated, and the sound source is not affected
5.This protection board uses 1.6 thick 1A copper surface, double-sided tin plating process, the input voltage is DC DC12V
Turn on the power (red) blue light flashing detection current, the indicator light is always on, the normal relay is closed, (red) blue light flashes until the suction is 3-5 seconds, if there is impact automatically adjusts the suction time ( Wait for the current to pass before picking up the relay)
The power supply can be the same as the power amplifier, suitable for DIY and car work.
The terminal block is 7.62 pitch, and the 1/2W metal film exceeds the standard. The internal resistance is reduced for high current design
Imported Omron relay as the core component is not afraid of contact sparking and oxidation, lossless transmission of sound
