Couldn't load pickup availability
Input Voltage 220V-240V
The LPS-80 Linear Power Supply by LHY AUDIO is a high-performance power supply designed for Hi-Fi audio systems, digital devices, and professional audio equipment. Utilizing a pure linear voltage regulation architecture, it delivers significantly lower ripple noise, stronger transient response, and cleaner power compared to traditional switching power supplies, enhancing audio quality and system stability.
Ultra-Low μV-Level Ripple Noise
- Premium Edition:<40μV (no load), <500μV (full load).
- Standard Edition: <100μV (no load), <500μV (full load).
- Utilizes LT3041/LT3086 parallel voltage regulation, reducing output impedance and improving dynamic response.
High Transient Current Capability
- Features low-dropout Schottky rectifiers + four Philips BC058 series electrolytic capacitors (4700μF 40V) for stable power delivery during high-dynamic music signals.
- Instantaneous current reaches 1.2~1.5x rated value (e.g., 5V: 7A rated / 8A peak), ensuring reliable performance under sudden load changes.
Low Impedance & High Bandwidth Design
- 4-layer gold-plated PCB minimizes signal loss and improves current transmission efficiency.
- X7R MLCC capacitors + high-precision low-drift resistors optimize high-frequency response.
