Features: Two large aluminum heat sinks ensures a better heat dissipation and more stable performance. Five 470uf/35V high frequency low resistance capacitors in parallel special for switch-mode power supply lower output ripple. 23mm large magnet and 1.0 copper wire provides high efficiency work. LED indicator light on board make work state more intuitive. TVS diode can prevent voltage spike from chip breakdown and ensures module safety. Two 50V/MLCC patch capacitors and high frequency low impedance electrochemical capacitors lower output ripple. Widely used for storage battery, power transformers, DIY adjustable regulated power supply, industrial equipment, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, etc. Specifications: Type: Non-isolated module (BUCK) Input Voltage: 4.5V to 30V Output Voltage: 0.8V to 30V (continuously adjustable, default 5V) Output Current: 0A to 12A Power: 100W Operating Temperature: -40℃ to +85℃ Frequency: 300KHz Max.
