To help users select the correct power supply more easily, we've summarized the maximum output current of all LHY Audio LPS models at different output voltages.π
β οΈγBefore You Buy β Please Check Firstγ
Before selecting an LHY Audio linear power supply, we strongly recommend checking the label on your device's original power adapter. Please pay attention to the following three parameters:
πΉ Output Voltage (V)
πΉ Rated Current (A)
πΉ DC Polarity (Center Positive / Center Negative)
12V/ 1A / Center Positive (inner positive / outer negative)
Always make sure that the output voltage is exactly the same, and choose a linear power supply that provides equal or higher current than the original adapter.
π All LHY Audio linear power supplies use Center Positive (inner positive / outer negative) DC output as standard. This is the most common configuration for audio equipment.
β οΈ If your device requires Center Negative (outer positive / inner negative) polarity, please contact our customer service before placing your order, so we can assist you accordingly.!<
βWhy Current Headroom Matters
Power = Voltage Γ Current (W = V Γ A)
In real audio systems, we strongly recommend not running a power supply near its maximum limit.
Adequate current headroom provides:
- Lower noise and ripple
- Better transient response
- More relaxed and natural sound
- Higher long-term reliability
π Choose headroom, not just βenoughβ.

π§ Official Recommendation
If your device requires 12V / 2A, choose a supply capable of at least 2.5A
For digital audio, clocks, servers, and switches: π More current headroom = better sonic stability
A power supply is never βtoo largeβ β only more relaxed π§
If you're unsure which model best suits your system, feel free to ask on the forum or contact us directly.
