1.With power indicator
2.With voltmeter display and voltmeter can be self-calibrated. Adopt more advanced voltage microprocessor, voltmeter error ±0.05V, measuring range 0~40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V)
3.Touch the button to switch the measured input or output voltage, and an indicator light shows which voltage is being measured, and save the setting, even if the power is off and then boot.
4.The voltmeter can be turned off. When it is not needed, it can be easily realized by touching the left button.
5.With terminal, no soldering iron can also be convenient to use, and retain the welding wire wiring points.
6.Input voltage 4.0~38V. (The input voltage must be more than 1.5V higher than the output voltage)
7.Adjustable output voltage range 1.25V ~ 36V continuously adjustable. (Input voltage must be 1.5V higher than output voltage)
8.Output current up to 5A, recommended to use within 4.5A.
9. Output power up to 75W, more than 50W please strengthen chip heat dissipation. (That is, a small radiator must be added.)
10.High conversion efficiency, up to 96% (efficiency is related to input and output voltage, current and pressure difference)
11.Working frequency: 180KHz
12.Load adjustment rate S (I) ≤0.8%, voltage adjustment rate S (U) ≤0.8%
13.With overheating protection and short circuit protection function (but there is always a short circuit in case of accident, try not short circuit)
14.Board size: 6.64* 3.89cm
