performance parameter
● with voltmeter display and voltmeter self-calibration.A more advanced voltage microprocessor is adopted, and the voltmeter error is ± 0.05v, ranging from 0 to 40V.(to ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5v)
● a touch of the button can switch the measurement input or output voltage, and an indicator shows which voltage is being measured, and save the setting, even if the power is off and then on.
● the voltmeter can be closed, when you do not need to touch the left button can be easily achieved.
● with terminal, no soldering iron can also be convenient to use, and retain the welding wire wiring points.
● input voltage: 4.0~40V.(the input voltage must be at least 1.5v higher than the output voltage)
● adjustable output voltage range 1.25V ~ 37V continuously adjustable.(the input voltage must be 1.5v higher than the output voltage)
● output current 3A, it is recommended to use in 2.0a, large current needs to strengthen heat dissipation.
● output power 20W, more than 15W, please strengthen heat dissipation.
● high conversion efficiency, averaging 88% (efficiency is related to input and output voltage, current and voltage difference)
● with anti - protection, anti - burning
● with overheating protection and short circuit protection
● size 6.6*3.6*14cm (length * width * height)
