600 Watt MOSFET Audio Power Amplifier PCB Board (Bare PCB)
This PCB is designed for building a high-power audio amplifier using a dual-rail DC power supply. Output performance depends on components used and assembly quality.
Output Power:
Maximum dynamic output power: up to 600 W (depends on supply voltage, load, components, and heat dissipation)
Total Harmonic Distortion (THD + N): approximately 0.1% at 400 W output with 4 Ω load and 1 kHz input signal (depends on components and build quality)
Working Voltage:
Dual supply: ±24 V to ±55 V DC
Recommended transformer: 24-0-24 VAC to 40-0-40 VAC (step-down), depending on required output power
Speaker Compatibility:
Supports 4 Ω and 8 Ω speaker loads
Suitable for speakers rated from 200 W to 600 W
Protection Provision:
PCB includes provision for fuses on each supply rail
Supports implementation of output short-circuit protection depending on components used
Construction:
Designed for through-hole components
No SMD components required
Components are commonly available
Configuration:
Bare PCB (components not included)
Requires proper heat sinking, component selection, and assembly for safe operation
Final performance depends on component quality and power supply design
Intended Use:
High-power audio amplifier construction
Subwoofer and full-range speaker amplifier projects
