7-40V 3A Multifunction Vehicle 4 USB Interface Car Charger 36/24/12/9V To 5V 3A Buck Module Step Down Board Lighter Powe

Description The previous version of the four USB all in parallel sharing five security this time each dual layer USB share a 5V 3A chip double insurance program two dual layer USB independent power supply each 3A the total current of 6A Professional can also be modified for the double adjustable that is two dual layer USB can be different voltage such as the left side of the supply voltage to the plate the voltage can be transferred to 5 3V but the right to power to the electronic dog the voltage only 5 08V The output voltage between 5 08 5 18V which is similar to the power on the market you can compensate for the loss of data lines USB voltage range is 4 75V 5 25V do not go beyond so as not to damage flat according to your request to adjust the voltage this is more difficult to say the general plate is 5 2 5 3V Colour GreenMaterial MetalSize 47 x 37 x 18mmCar 36 24 12 9V to 5V 3A mobile phones navigation and other power supply 4 usb charge Input voltage range of 7 40V in this range the output voltage stability This is a new component not a split parts new components dual core drive Performance to further improve more secure Using synchronous rectification technology 3A output current Integrated power MOSFET switch 95 efficiency Programmable soft start Stable low ESR output Cycle by cycle over current protection Fixed frequency 340Khz Input under voltage lockout System protection over current Limit Over voltage protection and thermal
