300W Digital Amplifier Speaker Protection Board Relay Protection Module 2.1 Three-Channel Speaker Delay Protection

Description

Quzenn Product parameters: voltage input DC12-16V or AC12-16VSound channel: three-channel can withstandPower: 300W x 3 or lessInstructions for use: Turn on the power indicator light, the work of the indicator light normal light relay suction, such as the impact of the protection board automatically adjusts the suction time (to be the current through the relay before suction). Power supply can be the same power supply with the amplifier, the three channels of the sound through of the negative pole of each line is , suitable for non-common ground and BTL circuit amplifier use: the terminals are 7.62 pitch, 1/2W metal film exceeds the standard use of the internal resistance to reduce the design specifically for high-current!Note: This protection board 15 seconds to switch on and off without a delay (the first time you switch on and off, to be 15 seconds after switching on before there is a delay)!Due to different batches, there may be differences in product appearance and printed text, which not affect useColour:As ShownMaterial:PCBPackage Contents:1 x Digital Amplifier BoardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
