S-300-12 DC12V 300W 25A DIY Regulated DC Switching Power Supply Power Inverter

1. Stable transformer inductor, all-copper coil, fast heat dissipation.2. High-capacity electrolytic capacitor, high temperature resistance of 105 degrees Celsius, long working time under full load, stable operation and long life.3. Filter ring capacitors, the circuit work is more stable, and the interference of variable pulsation ripples to the electronic circuit is reduced at the same time.4. Large mA fuse to effectively protect the circuit.5.
