Description:
--With delay and DC protection function (default 1.8V start control, DC sensitivity can be adjusted)
--This type of common power supply DC protection board uses optocoupler. Since the optocoupler has the isolation between the input and the output, and the electrical signal transmission has the characteristics of unidirectionality, it has good electrical insulation and anti-interference ability.
--Because the input end of the optocoupler is a current-type low-impedance component, it has a strong common-mode rejection capability, and achieves the separation of power and sound source 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.
--Power on (red) indicator light is on, working indicator light is on normally, the relay is closed, if there is an impact protection board automatically adjusts the pull-in time (the relay is closed only after the current passes)!
--The power supply can be the same power supply as the power amplifier, and each of the three-channel sound source negative wires is independent, which is suitable for non-common ground and BTL circuit power amplifiers.
--Terminals are 7.62 pitch, 1/2W metal film exceeds the standard, using internal resistance to reduce, specially designed for high current!
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)!
