300W Digital Amplifier Speaker Protection Board 2.1 Channel Relay Speaker Protection Module Boot Delay DC Protect

Product descrtion:

With delay and DC protection (default 3.2-3.5V start control, DC sensitivity can be adjusted) Protection board parameters: Voltage input: DC12-16V or AC12-16V Channel design: independent three channels Can withstand power: power within 300W*3 Size: 97*51*17MM Suitable: The power supply can be the same as that of the power amplifier. Each line of the negative pole of the three-channel audio source is independent. Note: Suitable for 2.1 three-channel cla D, cla A, discrete power amplifiers. Features: 1. This common power DC protection board uses an . Since the has input and output isolation, 2. Electrical signal transmiion has the characteristics of unidirectionality, so it has good electrical insulation and anti-interference ability. 3. Since the input end of the belongs to the low-resistance type of current type operation, it has strong common mode suppreion capability. 4. The power and sound source are separated, and the sound source will not be affected! Note: 1. The protection board uses 1.6 thi 1A copper surface, double-sided tin plating proce, the input voltage is  DC12V-16V or AC 12-16V. 2. Turn on the power (red) indicator light, the work indicator light is normal, the relay is closed, if the impact protection board automatically adjusts the suction time (waiting for the current to pa through the relay)! 3. The power supply can be the same as the power amplifier. Each of the three channels of the audio source is independent. It is suitable for non-common ground and BTL circuit amplifiers. 4. The terminal blo is 7.62 pitch, and the 1/2W metal film exceeds the standard. The internal resistance is reduced for high current design! 5. The j-oint v-enture S-ongle relay as the core component is not afr of contact sparking and oxidation, and lole transmiion of sound! Note: There is no delay when the protection board is turned on and off within 15 seconds (the first power-on-after turning off, there will be a delay after 15 seconds when it is turned on)!
