ITEM NAME:TDA2030A Electronic Audio Power Amplifier Module Board 30W DC 9-15V DIY Kit Product Description Description: Specification: Input voltage: AC9-15V or DC9-15V (DC input distinguishes polarity, AC input distinguishes polarity) Output power: Po = 15W + 15W (RL = 4ohm) Output impedance: 4-8Ohm PCB Size: 64x54x6mm/2.51x2.12x0.23'' Packaging weight: 103g Warm Tips: 1. TDA2030A has a load discharge voltage backlash protection circuit. If the crest value voltage of the power supply is 40V, then LC filter must be inserted between the five legs and the power supply. Diode voltage limiting (5 feet for any reason produced high voltage, generally the coil inductance of the horn, so that the voltage is equal to the voltage of the power supply) to ensure that the pulse train on the 5 feet is maintained within the specified range. 2. Thermal protection: Thermal protection has the following advantages: it can easily withstand the overload of the output (even for a long time), or when the ambient temperature exceeds, it plays a protective role. 3. Compared with the common circuit, the radiator can have a smaller safety factor. If the junction temperature exceeds, the device will not be damaged. If this happens, Po= (Ptot) and Io will be reduced. 4. The decoupling of ground wire and output must be well considered in the design of printed circuit boards, because these lines have large currents passing through them. 5. There is no need for insulation between radiator and radiator during assembly. Lead length should be as short as possible. Welding temperature should not exceed 260 ℃ for 12 seconds. 6. Although TDA2030A requires few components, the selected components must be of guaranteed quality. Note: Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
