Size: 94*60*27MM
With delay and DC protection (default 3.7V control, DC sensitivity can be adjusted)
This common power DC protection board uses an optocoupler. Since the optocoupler has input and output isolation from each other,
The electrical signal transmission has the characteristics of unidirectionality, and thus has good electrical insulation capability and anti-interference ability.
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
Features:
1. This protection board uses 1.6 thick 1A copper surface, double-sided tin plating process, the input voltage is DC DC12V.
2. Connect the power supply (red) blue light flashing detection current, the indicator light is always working normally, the relay is closed, (red) blue light flashing until the suction is 3-5 seconds, if there is impact automatically adjust the suction time (Before the current is passed, the relay is activated)
3. Power supply can be the same as the power amplifier, suitable for DIY and car amplifier.
4. 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
5. Imported OMRON relay as the core component is not afraid of contact ignition and oxidation, lossless transmission of sound
