Description

• Mini DC-DC four to zero 3A Step Down Power Supply Module Voltage Buck Converter Adjustable 97% 1 2 three 5V 9V 12V Specifications: 1 Input voltage: DC4 2 Output voltage: adjustable range (DC 0), fixed differ (1 2 3 5V 9V 12V) three Conversion efficiency: up to 97% 4 Output current: height value 3A, inside 2A for long-distance operating 5 Working temperature: -40℃～+85℃ 6 EN enable control pin: high level work, low point give up working, high point It is 2-5V, and the low level is ready 0V By default, there's a pull-up to the enter effective pole Scope of Application: DIY cellular energy supply, monitoring strength supply, children&;s car power supply, camera energy supply, vehicle energy supply, Communication kit strength supply, and many others Notice: 1 The wonderful and damaging poles of the enter terminals can't be reversed, in any other case the module can be burned directly; 2 The most input voltage and most output recent can't be convinced on the same time, and high power cannot be used for decades Voltage, high current, hot swap, eavesdrop on make stronger warmth dissipation; three This is a step-down module, the enter voltage is bigger than the output voltage; four The module defaults to adjustable output If a hard and fast output is required, stick to the pink line in the determine beneath Cut off the wire, after which join the pad on the ideally suited voltage position: How To Use Output Voltage: Adjustable voltage manufacturing facility default, can be utilized directly 12V lower the wire and solder the pads at 12V together 9V reduce the wire and solder the pads at 9V together 5V lower the wire and solder the pads at 5V collectively three reduce the wire and solder the pads at 3 collectively 2 reduce the wire and solder the pads at 2 collectively 1 cut the wire and solder the pads at 1 together Package Included: 1Pcs DC-DC Buck Converter Module or 2Pcs DC-DC Buck Converter Module
