Features:


1. It is a combination of 5v audio amplifier and 5v power supply board; the amp board working voltage is DC 5V, output power is 5W (2Ω 5V)/3W (4Ω 5V) / 1.8W (8Ω 5V); the power supply module input voltage range is DC 4-40V, adjustable output voltage range is DC 1.23-37V, max output current is 3A.


2. Artificial Material: this New-designed power amplifier is made of noble black immersion gold circuit board, imported KEMET speaker capacitor, large-capacity filter capacitor for channels. Besides, we customized black copper terminal blocks and gold-plated audio input terminal blocks for this new amplifier module.


3. Safe Protection: the class D dual-channel amp board is designed with input reverse connection protection, short circuit protection, over heat protection; what's more, EMI is allowed to pass; the step down power supply module is with reverse connection protection, over current protection, overheat protection, short circuit protection.


4. High Performance: the digital amplifier module is with high efficiency of over 90%, general harmonic distortion noise is less than 10%, low quiescent current and noise suppression; the voltage reducer conversion efficiency can up to 92%.
