Digital Lcd Display Automatic Buck Boost Converter Power Module

LCD input and output voltage, output current output power;Input anti-reverse protection, reverse connection will not burn;It can step up and step down, the output voltage can be adjusted freely from 0.5-30V, and the current limit of 0-4A can be adjusted arbitrarily;output anti-intrusion, no additional anti-backflow diode is needed for battery charging;The button controls the output on/off status, and you can set the power on or off by default;The rising and falling chips are used as the main controller, the external 60V 75A MOS tube is used as the switch, and the dual 60V 5A SS56 Schottky rectification, 60V voltage value, is superior to the immature XL6009 / LM2577 solution on the market (many devices have insufficient pressure values, MOS The pressure value of the tube and Schottky diode must be greater than the input plus input voltage value);Small output ripple, LC filter;With a heat sink, the transmitter module supports the isolation column.Parameter:Input voltage: 5.5-30V (input voltage 5V, can achieve normal buck - boost, but the voltage and current meter values are not accurate; below 4.7V, undervoltage protection)Output voltage: 0.5-30VOutput current: stable operation in 3A for a long time, strengthening heat up to 4AOutput power: 35W natural heat dissipation, heat dissipation 50WVoltage display resolution: 0.05VCurrent display resolution: 0.005AConversion efficiency: about 88%Soft start: Yes (load startup is very powerful, startup may fail)Input reverse protection: yesOutput anti-intrusion: yesShort circuit protection: yesWorking frequency: 180KHZSize: length * width * height 66 x 48 x 21 mmMounting hole: diameter 4mmColour:blueMaterial:Metal + SiliconePackage Contents:1 x buck-boost module1 x aluminum heat sink4 x silicone columnsOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
