1.Module Feature: Non-isolation booster2.Ectifier system:Not synchronous rectifier3.Input voltage:4.3V-32V4.Output voltage: 5V-52V5.Incoming current:4A(maximum)Colour:As the picture showsTransfer efficiency:94%(The highest)Normal efficiency for85%Switching frequency:400KHzOutput ripple:50mVLoad regulation:0.5%Voltage regulation:0.5%operating temperature:-40~+85Function key:1).Short press: input/output display options2).Moderate press: Enter the fine-tuning state .Increase or decrease the offset (the default is 0), when the voltage display inaccurate use .Short according to the regulation, long press or long according to restore3).Long press: the state of low power consumption, the digital tube and the lights are out, the normal work of the module. Click the button again to restore. Normal displayClockwise to adjust output voltage:Clockwise----- increasing voltageCounterclockwise----reduce the voltageMaterial: MetalPackage Contents:1 x Step-up ModuleOnly the above package content, other products are not included.Note: Light 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.
