LHY Audio Silent DC Power Supply (Low Noise Audiophile PSU)

Product Description

Compact, Ultra-Low Noise DC Power for Modern Audio Systems

The LHY Audio Silent DC is a high-performance DC power supply designed specifically for Hi-Fi audio systems. Combining advanced switching power technology with active noise cancellation, it delivers exceptionally clean and stable power in a compact, efficient form factor.

Why Silent DC?

Traditional switching power supplies offer efficiency and compact size but often introduce unwanted electrical noise. The Silent DC overcomes this by integrating a multi-stage filtering design with active noise cancellation—delivering μV-level low ripple performance typically associated with linear power supplies.

Ultra-Low Noise Performance

• μV-level ripple output for clean, stable power delivery
• Active noise cancellation reduces high-frequency interference
• Multi-stage CLC filtering further suppresses noise and improves stability

The result is a quieter background, improved clarity, and more stable system performance across your digital and audio components.

Key Features

• High-Performance Switching Design: Delivers strong current output with excellent efficiency and fast transient response
• Active Noise Cancellation: Reduces ripple and interference to achieve ultra-clean DC output
• Multi-Stage CLC Filtering: Minimises noise while improving power delivery stability
• Full Aluminium Chassis: Enhances heat dissipation and shields against interference
• Multiple Protection Systems: Includes short-circuit and overload protection
• Premium DC Cable Included: Hand-crafted pure copper cable for low resistance and stable transmission
• Compact Design: Space-saving and easy to integrate into any system

Flexible Compatibility

The Silent DC is available in multiple voltage configurations, allowing it to power a wide range of Hi-Fi and digital devices. Users can select the correct voltage, connector size, and polarity to ensure seamless compatibility.

Ideal Applications

• Network switches and routers
• Streamers and media devices
• DACs and digital components
• Compact or space-limited setups

What You Can Expect

With cleaner, more stable power, the Silent DC helps reduce system noise, improve clarity, and deliver a more refined and natural presentation—making it an ideal upgrade for modern digital audio systems.

Efficient, compact, and remarkably quiet—Silent DC delivers cleaner power without the size or heat of traditional linear supplies.
