DC Buck Converter Module,Voltage Regulator Step Down Module 5A 4.0V 38V to 1.25V 36V Adjustable

FEATURE:With power indicator,With voltmeter display and the voltmeter can be self-calibrated. A more advanced voltage microprocessor is adopted, the error of the voltmeter is ±0.05V, and the range is 0~40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V) HIGH PERFORMANCE:Buck Converter Buck Module,touch the button to switch between measuring input or output voltage, and there is an indicator light to show which voltage is being measured, and the setting is saved, even if the power is turned off and on again. ADVANTAGE:The voltmeter can be turned off, and it can be easily realized by tapping the button on the left when it is not needed.With overheating protection and short circuit protection EASY TO USE:Step Down Module with terminal blocks, it is easy to use without a soldering iron, and the wire connection points are reserved. PACKAGE LIST:1 x Step Down Module;1 x Heatsink;4 x Standoffs and Nuts,(Comes with heat sink for better heat dissipation, and several standoffs and nuts)
