1.European-style terminal: manufactured according to European standards, with superior flame retardant performance, safety and environmental protection. The choice of large terminals is not only the consideration of power, but also the pursuit of quality.

2. Metallized polyester film capacitor: with pulse strength, high reliability and good self-healing.

3. Patch inductance: When the current through the inductor coil increases, the self-induced electromotive force generated by the inductor coil is opposite to the current direction, which prevents the current from increasing. After inductance filtering, the pulsation of load current and voltage decreases. When the current through the inductor coil decreases, the self-induced electromotive force is in the same direction as the current direction, which prevents the current from decreasing and releases the stored energy at the same time to compensate for the current decrease, and the waveform becomes smooth.

4. Chip aluminum electrolytic capacitor: the capacitance is large, the chip capacitor and the bottom plate are soldered with tin, and there is no solder joint on the back of the circuit board, so there is no possibility of short circuit. The chip capacitor is higher than the plug-in capacitor in terms of components and production process cost.

5. Convective cooling array: the heat emitted by the chip is convected from the center through staggered channels

6. Type heat dissipation, heat dissipation efficiency is higher.

7. TPA3116D2 chip (originally produced by Texas instruments, USA): wide voltage range of 12-26V,TPA3116D2 chip provides comprehensive protection against short circuit, overheating, overvoltage, undervoltage and DC faults. In case of overload, the device will report the fault condition to the processor, thus preventing itself from being damaged.
