Without Tongzhu
With a voltage meter displayVoltmeter error ± 0.1V, Range 0 ~ 40V. (Note: The input voltage is below 4V, the onboard voltage meter does not work does not show)
OriginalTouch of a buttonSwitching measuring input or output voltage, and has a light show which is being measured voltages, and keep the last setting, even power off and then power
Voltmeter can be turned off, Press the switch for one second or more and less than four seconds, let go you can close
Input and output voltage measurement error than the standard function,PressSwitch more than 4 seconds, let go after entering the voltage measurement error than the standard features, this time in lights (calibration input), the digital display flashes the more positive (factory parameter is 0.0), thenShort pressButton to change the value (Values range from -0.5 to 0.5, the unit is V), A positive number indicates upward adjustment, a negative number indicates downward calibration. After adjusting the input end of the calibrated values,PressButton for 2 seconds or more, let go into the output of the calibration error, this time out the lights (calibrated output), and shows the value of the output of the calibration, adjustment, and input the same way,Better than the standard value of the entire output of the following,PressButton for 2 seconds or more, let go to save the set value and return to normal display voltage,Correction value is set to take effect immediately, and non-volatile.
With terminals, no iron can also be easy to use, and retention bond wire connection point
Input voltage4.0 ~ 40V(Input voltage must be output voltage higher than 1v more.)
Adjustable output voltage range1.25V ~ 37VContinuously adjustable(Input voltage must be output voltage is higher than 1V above)
MaximumOutput current up3A,Normal and stable operating current2A
Using the internal oscillator frequency 150KHz, belongs to the second generation of switching voltage regulator, low power consumption, high efficiency
