Sell HW-319B LM2596S 3A DC to DC Power Supply Step-Down Module w/Digital Display best price

HW-319B LM2596S Adjustable DC-DC Step Down Power Supply Voltage Regulator Module with Digital Display Feature: 1. With voltmeter display, advanced microprocessor, voltmeter error ±0.05V, range 0-40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4V) 2. Tap the button on the right to switch the measurement input or output voltage, and there is an indicator light to show which voltage is being measured, and the settings are saved, even if the power is turned off and on again 3. The voltmeter can be turned off, and it can be easily realized by touching the button on the left when it is not needed 4. With terminal blocks, it is easy to use without soldering iron, and the connection points of welding wires are reserved 5. Input voltage 4.0-40V (The input voltage must be higher than the output voltage by more than 1.5V.) 6. Adjustable output voltage range 1.25V-37V continuously adjustable (input voltage must be 1.5V higher than output voltage) 7. The maximum output current can be as high as 3A, and the normal stable working current is 2A 8. The internal oscillation frequency of 150KHz is adopted, which belongs to the second-generation switching voltage regulator, which has low power consumption and high efficiency. 9. With overheating protection and short circuit protection function.
