With voltage meter display; voltage meter error of ±0.1V; the range among 0~40V. (note: to ensure the voltage meter accuracy, please make sure that the input voltage is 4.2V or more).
Voltage meter can be closed by long pressing button(minimum power loss).
The range of input voltage is 4.2~40V and output voltage is1.25V~37V ,which are continuously adjustable.(The input voltage must 1V higher than output voltage)
Maximum output current can be as high as 3A, but normal and stable working current is 2A.
Use 150KHZ internal oscillation frequency, which is belong to the second generation of switch voltage regulator with low consumption and high efficiency.
