NEW ZK-3002 Amplifier Board 300W Dual Channel TPA3255 Chip Dual Channel Amplifier Board for Audio

Product Description1. Our amplifier adopts the advanced TPA3255 chip, which incorporates the most advanced digital audio processing technology to deliver an extraordinary audio experience. Its efficient power conversion performance can achieve 300W + 300W dual-channel output and 600W mono output, ensuring powerful and clear audio output.2. To meet different audio needs, our amplifiers support bridging function, allowing users to flexibly configure the system. In bridge mode, the power output is significantly increased, providing users with more diverse audio layouts and immersive sound experiences.3. Equipped with a large high-efficiency heat sink to ensure stable operation under continuous high power output. The enlarged and thicker heat sink can effectively dissipate the heat generated, improve the operating efficiency of the amplifier circuit board, and ensure excellent performance under high load conditions.4. The use of dedicated inductors for digital amplifiers ensures low distortion in audio signal transmission. This well-designed detail further enhances the performance of the amplifier, making it an ideal power amplifier for audiophiles seeking high-fidelity audio enjoyment.Specification:Power amplifier chip: TPA3255Product model: ZK-3002Adaptable power supply: Working voltage range 18-50VDC, limit 53VCompatible speakers: 3-8 ohms in BTL dual-channel mode, 50-300W; 2-8 ohms in PBTL mono mode, 100-600WCooling method: temperature control, automatic air cooling, or manual selection of fan to keep rotating.Bridge connection method: cut off the power first, turn the No. 1 dial switch to the ON position, short-circuit R+L+ at the output terminals for parallel output, and short-circuit R-L- for parallel output.Maximum power: In BTL mode, 2300W/50V4Ω, 160W/50V8Ω; in PBTL mode, 600W/50V2Ω, 300W/50V4Ω, 160W/50V8ΩProtection mechanism: input undervoltage, overheating, overcurrent, short circuit protection.Note:1.There is no input anti-reverse protection, the positive and negative poles cannot be connected reversely!2.It is recommended to use a DC power supply with a voltage of 36-48V and a current of more than 10A. The higher the voltage, the greater the output power.Package includes:1Amplifier Board
