300W DC-DC Step Down Module Konverter 7V~40V na 0.8V~28V

300W DC-DC Step Down Module Converter Adjustable Power Supply Buck Module Constant Current LED Driver Module 7V~40V to 0.8V~28V

Features:

• Indicator light current is 0.1 times of the current which is used to identify whether it is fully charged.
• Made from special IC and high precision sampling resistors which ensures a more stable constant current, specially fit LED driver.
• Four high frequency capacitors can reduce output ripple and good for stability.
• Two independent heat sink design are better for heat dissipation.
• The inductor of large sendust core and double copper wiring would improve efficiency and decrease heat.
• Widely used for high power LED drive, lithium or lead-acid battery, low voltage system power supply, 6V, 12V, 14V, 24V battery charging and regulated power supply.
• When power tube temperature is over 65° , please add cooling fan to enhance heat dissipation.
