LHY LPS-50 50W Audio-Grade Ultra-Low Noise Linear Power Supply

The LHY LPS-50 Linear Power Supply is designed for high-end audio and video equipment, delivering ultra-pure μV-level power to minimize grid interference and enhance audiovisual performance. Featuring precision voltage regulation, CLC filtering, and high-quality components, it ensures ultra-low ripple noise (as low as 9μV), high stability, and long-term reliability. Compatible with devices such as MAC MINI, hard drive enclosures, routers, switches, NUCs, and laptops, it provides a cleaner dynamic range, richer details, and more authentic sound and image reproduction.

• Ultra-Low Noise Regulation: Precision voltage reference + high-speed op-amp + MOSFET power transistors for stable and clean power output.
• CLC Filtering System: Triple-stage input/output filtering for significantly reduced ripple interference.
• High-Current Rectifier Bridge: Heat-resistant and high-current tolerant for long-term stable operation.
• Custom Transformer: Japanese core + high-purity oxygen-free copper winding for efficient energy transfer.
• Low-Impedance MOSFET: Effectively suppresses AC circuit interference, improving dynamic performance.
• Ultra-low ripple (≤9μV) – Minimizes current noise and reduces harsh high-frequency distortion.
• Wider dynamic range – More stable soundstage and enhanced detail retrieval.
• Multi-device compatibility – Supports MAC MINI, NUC, routers, and other Hi-Fi equipment.
• Handcrafted construction – Precision soldering by engineers for superior build quality.
• Ground switch (ISOLATED/GND modes) – Adaptable to different device requirements.

1. Connect Your Device: Plug the power supply output into your audio/video equipment (e.g., DAC, network switch).
2. Select Grounding Mode (Optional):ISOLATED (Default): DC negative terminal isolated from AC ground to prevent ground loops (ideal for most setups).GND Mode: DC negative connected to AC ground for devices requiring direct grounding.
3. Power On: Switch on the unit and monitor the output voltage display to ensure proper operation.
4. Fine-Tuning (If Needed): Adjust voltage (±2.5%) for optimal performance based on your equipment.
