Description:
300W 12A DC-DC Buck Converter Step-Down 7-32V TO 0.8-28V Adjustable Power Supply Module contains two large aluminum heat sinks ensuring better heat dissipation and more stable performance. It contains five low resistance capacitors of 470uF/35V in parallel especially for the switch mode power supply, a 23mm large magnet, and 1.0 copper wire to provide high-efficiency work. For safe module operation, this module contains a TVs Diode to prevent voltage surge from breaking the chip. This module is widely used for storage batteries, power transformers, DIY adjustable regulated power supply, industrial equipment, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, etc.
This module can be applied to the input voltage floating relatively large, the output requirements of more stable areas. Such as:
- 12V battery (10-14V) regulated output 12V, 12V power supply to the device, 24V battery regulator 24V; can be used as a car power supply
- Solar panel voltage regulator, solar panel voltage fluctuations are relatively large, this module can regulate the output, to the device power supply or to charge the battery to use.
- Driving high-power LED lights, constant current drive, such as 12V battery drive 4 string LED lights, LED and battery voltage difference between this time.
