The AIYIMA 48V10A GaN Power Supply is a high-efficiency 480W switching power adapter utilizing Gallium Nitride technology. It is engineered primarily for high-performance Class-D audio amplifiers like the TPA3255 series, delivering stable DC voltage with minimal heat and compact dimensions

 

Core Advantages of GaN Technology:

• Thermal Management: GaN operates with lower switching losses. This allows for a fanless, completely quiet design that eliminates mechanical noise in audio environments.
• Form Factor: It is roughly half the weight and significantly smaller than traditional silicon-based 480W transformers. Typical weights sit around 1.0kg to 1.1kg.

Ultra-Low Ripple: Premium GaN blocks maintain a clean DC output with voltage ripple constrained to the millivolt range, filtering background hum

 

Technical Specifications:

• Input Voltage: AC 100–240V, 50/60Hz
• Output Voltage: DC 48V
• Output Current/Power: 10A max / 480W max
• DC Plug Size: 5.5mm × 2.5mm (inner positive, outer negative)
• Technology: GaN (Gallium Nitride) for reduced switching losses and lower operating temperatures

 

Key Features:

• High Efficiency: Lower thermal emission and superior energy conversion compared to older silicon-based bricks.
• Low Noise & Ripple: Clean power delivery ideal for sensitive high-fidelity audio gear.
• Built-in Protections: Overload, over-temperature, over-voltage, and short-circuit safeguards.
• Fanless Design: Operates silently without an active cooling fan.

 

Compatibility

• Audio Amps: Specially matched for desktop and mono Class-D audio amplifiers, including models like AIYIMA A07 Pro, A07 Max, A70, and Fosi Audio variants.
