DC to DC 15W Adjustable USB Step Up Down Power CVCC Buck

This is a DC adjustable constant voltage constant current step up/down power module with LED digital tube display. Display output voltage output current and output power. Adjustable output voltage and current. Set output current to meet the require. It can be used as ordinary buck power supply module charge and LED constant current driver. Simple and efficient practical.Features:With intelligent quick charge decapitation solve the problem of insufficient power of USB input port. Support mainstream fast charge protocol QC2.0 3.0 FCP SCP AFC.High power 15W 2A current can be used for fan speed regulation desktop power adjustable charge router power etc.Used as USB input adjustable desktop power can adjust output voltage arbitrarily and limit current 0-2A wide input 4-13V wide output 0.5-30V can be adjusted arbitrarily with short circuit protection short connection does not burn.As a USB charging cable arbitrarily adjust the charging voltage and maximum charging current arbitrary voltage with constant current anti-reverse irrigation to meet most battery charging requirements.Multiple protection: short circuit over current over temperature over power over voltage protection charging and reverse irrigation protection.Specifications:Input voltage: 4-13VOutput voltage: 0.5-30VOutput current: 0-2AOutput power: less than 15WVoltage display: resolution is 0.1V factory accuracy is 0.1VCurrent display: resolution 0.01A measuring range 0-2.2A factory accuracy 0.05APower display: 0.00W-15.0WOperating current: about 30mAhItem size: 85 * 36 * 15mm / 3.3 * 1.4 * 0.6inItem weight: 30g / 1.1ouncePackage size: 90 * 40 * 20mm / 3.5 * 1.6 * 0.8inPackage weight: 53g / 1.9ouncePackage list:1 * Voltage Regulator
