TPA3116D2 DC 8V To 25V 100W Single / Dual Channnel Digital Amplifier Board Subwoofer Amplifier Board

Parameter: PCB size: 75*60mm (length*width) Power usage range: DC 8V to 25V Power interface: standard 5.5mm power jack Output power: singal channel output: 100W double channel output: 50W (left channel) + 50W (right channel) efficiency up to 90% Note: 1. Turning the knob left to the bottom is the off state; 2. Right operation: first connect the external power supply and power connector of the digital amplifier, and then connect the 220V power cord of the external power supply to the mains outlet; 3. Incorrect operation: connect the mains interface of the external power supply first, and then input the output interface of the external power supply to the digital amplifier. Because the digital amplifier has a filter capacitor, this capacitor charges and discharges, producing a low-voltage spark within 0.1 seconds of contact. Pcakage included: 1 X TPA3116D2 digital amplifier board
