600W+600W Dual TPA3255 Amplifier Board Fan Cooling Class D Stereo Amplifier Board DC18-50V

The 6002 is a pure post-stage stereo amplifier board built on two original TPA3255 chips, delivering up to 600W + 600W into 2 ohm loads at 48V and 300W + 300W into 4 ohm loads. With a 90dB signal-to-noise ratio, THD+N below 0.05% and 38dB maximum gain, it is designed for professional stereo systems, high-end home theater, floor-standing speakers and commercial audio projects. An integrated high-speed cooling fan, thickened heat sink and gold-capped filter capacitors keep the module stable under continuous high-power use.

• Dual TPA3255 chips: two original TI TPA3255 class D amplifier chips deliver 600W+600W peak stereo output with low distortion and high resolution.
• Active cooling: high-speed fan plus thickened aluminium heat sink maintains full power output during long continuous operation.
• Audiophile-grade components: low ESR filtering capacitors, gold-capped electrolytic capacitors, high-current shielded inductors and precise PCB layout.
• Wide power range: DC 18-50V input, 10A or above, recommended 36-48V; works with 4-8 ohm speakers.
• Simple integration: compact 134 x 100 x 37mm PCB with XH2.54-3P stereo input, 3.5mm jack input, shielded cable included, and gold-plated high-current DC socket or 2P terminal block.
• Volume and protection: on-board 0-38dB volume potentiometer with power indicator light (flashes when input voltage is below 18V), plus input undervoltage, overheat, overcurrent and short circuit protection.
• OEM / ODM ready: custom logo and PCB colour, custom packaging, function fine-tuning and 7-day fast sampling.

Two independent TPA3255 chips work in a stereo configuration, each driving one channel. The feedback design and high-speed gate driver error correction keep distortion low across the full audio band, while the dual-chip layout spreads heat and current so the board holds its rated output instead of throttling.

A high-speed fan pulls air across a thickened brushed aluminium heat sink, and low ESR filtering capacitors plus high-current shielded inductors keep the supply clean under heavy load. A gold-plated DC socket or 2P terminal block, gold-capped electrolytic capacitors and oxygen-free copper inductors are used throughout.

The board accepts DC 18-50V with 10A or above current; 24V, 36V and 48V adapters are all supported, and higher voltage together with lower speaker impedance raises output power. Please make sure the adapter power is higher than the actual working power of the amplifier, and connect the 2P terminal block before switching on to avoid excessive current damage.

The main PCB measures 134 x 100 x 37mm and the complete assembly with fan and heat sink measures 135 x 118 x 40mm, so the module fits into standard amplifier chassis, active speaker cabinets and custom OEM housings. Left and right speaker terminals, stereo input and volume control are arranged on the board edge for quick wiring.

Factory-direct OEM and ODM support includes custom logo silk-screen, multiple PCB colour options (standard black, red, blue), personalised packaging design, function fine-tuning and 7-day fast sampling for audio brands, professional audio manufacturers, speaker system integrators and private label projects.

Suited to professional stereo audio systems, high-end home theater, floor-standing speaker systems, commercial audio products, custom amplifier projects, distributors and bulk wholesale buyers.
