Description

LM2596 Buck Step-down Power Converter Module 4.2-40V to 1.25-37V LED Voltmeter Features: 1. Input voltage range: 4.2-40 v (40 v to limit the highest voltage). 2. Output voltage range: 1.25V - 37V (decompression mode, input output must be greater than 1 V above). 3. Output current: 3A continuous outputs, normal and stable working current in 2A. 4 .Ripple frequency: 150 KHz. 5. Voltmeter precision: ¡À 5 ¡ë. 6. Static power: 20 ma (and input voltage output voltage and digital tube color is closely related to the actual current will exist deviation). 7. Weight: 33g. 8. With voltage display function, the displayed accuracy is ¡À 0.05V, range is 0 - 40V. (Note: in order to voltage display more accurate, please ensure that the input voltage is higher than 4V) . 9. Button to switch measurement of the input or output voltage£¬and LED indicates the current measurement of the input or output voltage; Mentioned in these states are able to be memorized, is not lost even if the power is disconnected. 10. Continuously adjustable output voltage range of 1.25V -37V, 4.2-40V input voltage range.£¨The input voltage is at least high than the output voltage of 1.5V£©. 11. High efficiency, 150 kHz fixed frequency internal oscillator. 12. Guaranteed 3A output load current. 13. Thermal shutdown and current limit protection. 14. IN +: input positive/IN - : input negative. 15. OUT +: output positive/OUT - : output negative. Package includes: 1* LM2596 Voltage Regulator Module
