2.1 CH CLASS D SPEAKER PROTECTION 300W

Features:

1: With delay and DC protection function

2: Support DC and AC power supply

3: No independent power supply

4: Can share power

5: Widely used

Describe:

With delay and DC protection function (default 1.8V start control, DC sensitivity can be adjusted)

This common power supply DC protection board uses optocouplers. Because optocouplers are isolated from each other between input and output,

Electric signal transmission has the characteristics of unidirectionality, etc., so it has good electrical insulation and anti-interference ability.

Also, because the input end of the optocoupler is a current-type low-impedance component, it has a strong common-mode rejection capability.

The power supply and the sound source are separated without affecting the sound source!

This protection board uses 1.6 thick 1A copper surface, double-sided tin plating process, and the input voltage is DC 12V-16V or AC 12-16V
