LHY AUDIO SilentDC 84W Active Noise-Cancelling DC Power Supply DC Regulated Power Supply (20V 4.2A)

Description:
SilentDC is a cost-effective HiFi audiophile-grade low-noise DC regulated power supply launched by LHY AUDIO. Its DC output ripple can be as low as the microvolt (μV) level, while its size is significantly smaller than that of traditional HiFi linear DC power supplies. Inside, SilentDC adopts a high-performance switching power module, combined with a multi-stage LC filter matrix and active noise-cancellation circuitry. This design effectively suppresses voltage spikes and high-frequency oscillations, improving both power supply safety and audio purity. It also significantly reduces EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) noise at the input source, delivering a cleaner and more stable power environment.

SilentDC features a full aluminum alloy casing that is not only sturdy and durable but also provides excellent heat dissipation to ensure long-term stable operation. In addition, the power supply includes built-in short-circuit and overload protection and comes equipped with a hand-crafted pure copper DC power cable, offering higher power transmission capability and lower energy loss.

SilentDC offers multiple output voltage options, making it compatible with a wide range of high-end HiFi audio equipment. Users can choose based on their device's input voltage, connector size, and polarity to ensure proper compatibility and enjoy an almost noiseless, high-purity power supply solution.

Features:
* High-performance switching power module — Delivers high current output, excellent transient response, compact size, and high efficiency.
* Multi-stage CLC filter matrix circuit — Significantly reduces ripple and noise, improves transient response speed, and lowers the internal resistance of the power supply.
* Active noise-cancellation system — Further reduces DC ripple and noise, achieving output at the microvolt (μV) level to ensure cleaner, more stable, and interference-free power.
* Durable full aluminum alloy chassis — Offers outstanding heat dissipation and ensures long-term stable operation.
* Multiple protection mechanisms — Built-in short-circuit and overload protection to guarantee safe and reliable device operation.
* High-quality DC power cable — Made from hand-crafted pure copper wire, featuring low transmission loss and ensuring stable power output.
* Compact and lightweight — Space-saving and easy to place. Suitable for more usage scenarios.

How to Choose the Right Specification:
1. Confirm the input voltage of your device (check the device's power port or user manual).
2. Select a power supply model with the same voltage as your device's input voltage.
3. Ensure that your device's required current is less than or equal to the rated output current of this power supply.
4. Confirm that the connector size and polarity match.
