Speck:
● with a voltage meter display , voltmeter error ± 0.1V, range 0 ~ 40V. (Note: The input voltage is below 4V, the onboard voltage display table does not work)
● Original touch of a button to switch measuring input or output voltage, and has a light show which is being measured voltages, and hold the last set, even if power is turned on again
● voltmeter to turn off , press the switch for one second or more and less than 4 seconds, you can let go Close
● input and output voltages than the standard error of measurement functions , press the switch more than 4 seconds, let go after entering voltage measurement error than the standard features, this time in bright light (calibration input), the digital display flashes compared with a positive value (factory parameter is 0.0 ), then press the button to change the value ( value in the range of -0.5 to 0.5, the unit is V ), a positive number indicates upward calibration, negative number indicates downward calibration. After adjusting the input calibrated value end, press the button more than 2 seconds, let go into the error correction output terminal, this time out the lights (calibration output terminal), and displays the same calibration value output terminal, adjustment method and the input, the whole good after comparing the output of the reference value, press the button for two seconds or more, and let go to save the set value and return to normal display voltage correction value setting takes effect immediately and is non-volatile.
● with terminals, no iron can also be easy to use, and retention wire terminal points
Input voltage 4.0 ~ 40V ( input voltage must be higher than the voltage to be output 1v above. )
● adjustable output voltage range of 1.25V ~ 37V continuously adjustable (input voltage must be output voltage is higher than 1V above)
● The maximum output current up to 3A, normal and stable working current 2A
● using the internal oscillator frequency 150KHz, belongs to the second generation of switching voltage regulator, low power consumption, high efficiency
