With voltage meter display,voltage meter error ofÂ±0.1V, the range of 0~40V. (note: to ensure that the voltage meter accuracy, please make sure that the input voltage is 4.2V or more).
Low light touch button switch measurement input or output voltage,and a light show is voltage measurement which road, and keep the last set, even if the power switch on again.
Voltmeter fine-tuning: hold down the button about 1-2s into fine-tuning mode, can remove button on the calibration at this time. (please do not use standby function, usually).
Low voltage meter can be closed,long press button closure voltmeter (minimum power loss).
Input voltage:4.2~40v(input voltage must be higher than to the output voltage of more than 1v).
Output voltage adjustable range1.25V~37V adjustable (input voltage must be higher than to the output voltage is more than 1V).
Maximum output current can be as high as 3A,normal and stableworking current in 2A.
Low the internal oscillation frequency, 150KHZ belong to the second generation of switch voltage regulator,low consumption, high efficiency.
