SMAKN DC-DC 6-24V to 5V 3A USB Charging Module Step-down Buck Power Supply Module

*Module Properties: Non-isolated High efficiency synchronous buck regulator, constant voltage module. *Input voltage: DC 7-40V input DC voltage. (Prohibition AC input). *Output voltage: DC 5V voltage output (perfect simulation computer USB output). *Output Current: Rated 3A, enhance heat dissipation maximum 4A (adaptive output) with 5A insurance. *Output short circuit protection: Yes. Automatic recovery after normal output short releasing more secure! *Low pressure: 1V (as is the step-down voltage regulator, the input voltage than output high above 1V). *Output power: natural cooling rated 15W (5V 3A output). *Conversion efficiency: up to 98% *Operating temperature: Industrial grade (-40 ? to + 85 ?). *Load regulation: 1%. *Voltage regulation: 0.5%. *Dynamic response speed: 5% 200uS. *Indicators: There, 5V USB output blue power indicator. *Input reverse polarity protection: None, please enter the string diodes. *Wiring: input terminals. *Size:47.6mm * 20.8mm * 13mm(L*W*H).
