Build a high-power stereo audio project with the ZK-6002 amplifier board. Two TPA3255 chips drive separate left and right channels, while aluminium heat sinks and temperature-controlled fan cooling help manage heat during operation.
Specifications
- Configuration: 2.0-channel stereo, non-bridged.
- Amplifier chips: two TPA3255 chips.
- Supply: DC 18–50V; recommended DC 36–48V, 10A or higher.
- Supported speaker impedance: 2–8Ω.
- Supplier-listed output at 48V: 300W per channel at 4Ω or up to 600W per channel at 2Ω.
- Supplier-listed signal-to-noise ratio: 90dB.
- Supplier-listed THD+N: less than 0.05%.
- Maximum gain: 38dB.
- Input: stereo via XH2.54-3P connector.
- Dimensions: 136 × 100 × 38mm.
Cooling and protection
The fan briefly runs during power-on self-test and is listed to activate above 50°C. Listed protections include input undervoltage, overheating, overcurrent and short circuit. There is no input reverse-polarity protection.
Included
One amplifier board and one 3P double-ended shielded cable. Power supply and additional audio cables are not included.
Installation requirements
DC power only; never connect AC power. Check polarity before connection and keep the supply within the stated 18–50V range. This model does not support bridging: do not connect the left and right outputs together. Output figures are supplier-listed maxima and depend on supply capacity, speaker load, cooling and audio input; they are not guaranteed continuous ratings. This is a DIY component, not a complete amplifier enclosure or speaker system.
