ITEM NAME:TDA2030A Audio Power Amplifier Board Module Mono Stereo Amp Subwoofer DIY K B4O6 TDA2030A Audio Power Amplifier Board Module Mono Stereo Amp Subwoofer DIY K B4O6 Operating voltage: 9-24VDC(recommedded DC12V,this voltage to the heat sink requirements are very low)Maximum supply voltage of this board is actually up to 40V,but you need to change the board39;s own electrolytic capacitor C1,the capacitor voltage value is higher than the supply voltage can be use) Total harmonic distortion: 0.08% (Po = 0.1 to 14W, RL = 4Omega;) Static current: about 25mA Speaker Impedance: 4Omega;-8Omega; Output Power: 18W Color: Green Material: CCL SNR: 94dB-106dB Heat: the higher voltage supply ,the greater volume, the higher the heat. Note: This is a DIY kits,you should solder it by yourself! Package included:1x green plate and plug-in capacitors 7x resistors 1x needle 1x IC 1x screw 5x capacitance 1x yellow interfaces 1x blue card Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
