DC 10-30V ZK-2001 TPA3221 Dual Channel Pure Rear Stage Digital Amplifier Board 100W+100W AMP Bridged Mono Subwoofer Speaker

Features: 1. High-efficiency TPA3221 chip, supports 100W+100W dual-channel/200W mono output. 2. Wide operating voltage range (10-30V DC), 24-30V high voltage is recommended for greater power. 3. Supports BTL and PBTL modes, adapts to a variety of impedance speakers, and meets the needs of different scenarios. 4. Built-in multiple protection mechanisms, including undervoltage, overheating, overcurrent and short circuit protection, safe and reliable. 5. Adopts multi-tooth heat sink design to effectively improve heat dissipation efficiency and ensure long-term stable operation. Product parameters: Product name: 100W+100W dual-channel/200W mono pure post-stage amplifier board Amplifier chip: TPA3221 Product model: 2001 Adaptive power supply: operating voltage range 10-30V DC, limit 31V. It is recommended to use a DC power supply with a voltage of 24-30V and a current of more than 10A. The higher the voltage, the greater the output power. Never connect to AC power, otherwise it will burn out!
