Item Name: 5A 75W DC-DC Converter Adjustable Step-Down Power Supply Module w/Voltmeter. Smart TV Box Android Quad Core HDMI 1080P Wifi Streaming Media Player UK
Feature:
1. With Power Indicator Lamp.
2. It has a voltmeter display and can be self-calibrated. A more advanced voltage microprocessor is used. 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.)
3. Touch the button to switch the measurement of input or output voltage, and have an indicator to show which voltage is being measured, and save the settings, even if the power is off and then turn on.
4. The voltmeter can be turned off, and it can be easily realized by touching the left button when it is not needed.
5. With terminal, it is easy to use without soldering iron, and retains the connection points of welding wire.
6. The input voltage is 4.0-38V. (Input voltage must be 1.5V higher than output voltage).
7. The adjustable output voltage ranges from 1.25V to 36V. (Input voltage must be 1.5V higher than output voltage).
8. The output current can reach 5A. It is recommended to use within 4.5A.
9. The output power can reach 75W. If the output power exceeds 50W, please strengthen the heat dissipation of the chip. (that is, a small radiator must be added).
10. High conversion efficiency, up to 96% (efficiency is related to input, output voltage, current and voltage difference).
11. It has the functions of overheating protection and short circuit protection (but in case of accidents, try not to short circuit).
