Maximum output current: 2A (recommended for use within 1A)Input voltage: 2 v ~ 24 vMaximum output voltage:> 28 v (recommended for use within 26V)Efficiency:> 93%Size: 30mm * 17mm * 14mm (L * W * H)This module is a step-up module, the output voltage is greater than the input voltage.Peak current output current does not exceed 2A.Note:1. Input voltage should not exceed the maximum input voltage2. Peak current output current does not exceed 2A3. When the module output voltage can not be adjusted, always equal to the input voltage when the first 20 laps counterclockwise rotary potentiometer or more, then you can use the module properly regulate the voltage. Surge mode: potentiometer face chest, counterclockwise turn boost!
