Vender 15W Adjustable Dc-Dc Cc Cv Usb 5V to 3.3V 9V 12V 24V 30V Step Up / Down Power Supply ule Adjustable Boost Buck Converter with Outer Case & 5V-24V al mejor precio

2 * ule: 1*a + 1*b Is a DC adjustable step up/down power supply ule with LED digital tube display.Display output voltage in real time.Rotate potentiometer to adjust output voltage.Set output voltage to meet the require.It can be used as ordinary buck power supply ule.Simple and efficient,practical. Features:Low power supply.Wide voltage output.Support boost and buck.Long handle potentiometer adjustment Using Steps:Input DC 5V from USB male socket;Adjust output voltage by potentiometer to meet require;Remove input voltage;Connect load at output terminal;Re-connect power ON and enjoy using. Maximum output current (constant current value) Configuration method: Switch to current screen, shorten directly the output terminal to adjust the DC potentiometer. The CV voltage adjustment potentiometer rotates clockwise to increase the output voltage. The indicator lights CC - constant current indicator light, bright when the constant current (red); Status indicator on the output (green); Type: Voltage Regulator Select button: short pressure switch between voltage, current, power, wheel display; Long press or exit calibration e; On / off button button: short pressure control of the output end that turns on or off; long pressure: set the default power on to be off or on, press to release more than 3 s, it will be displayed for each power-by default there is an output, and the screen off means there is no default output each time turn on the energy. The current adjustment potentiometer CC turns clockwise to increase the current limit value. When the charging current reaches the limit current, it enters the constant current state (keep in mind that the output current can be increased without adjusting the potentiometer.) At constant voltage, the output current only depends on the load, varies according to load);Colour:blue Material:Metal + plastic Size:84*21*35mm/70*26*22mm Output Voltage:DC 1.0V-24.0V Output Power:3W(Max) Conversion efficiency:94% Working current:30mA Working Temperature range:-20 Celsius-85 Celsius Working Humidity range:0%-95%RH Package Contents: 2 * ule Only 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.
