TeOhk Dc-Dc Buck Converter Step Down Voltage Constant Current Converter Module Voltage Regulator Power Converter Adjustable Power Regulator Board with LED Voltmeter & USB Output

1. With crystal case, safe, practical, convenient and beautiful. 2. On-board voltage, current and power meter, you can easily use this module without a multimeter, which is simpler and more intuitive. 3. Onboard USB interface makes it easy to charge your digital products. (Note: The USB output voltage is the same as the module output voltage. It is not a fixed 5V output. Please confirm before charging the USB device.) 4. High power, high efficiency, 5A, low ripple; 5.With current limiting protection, the module will not burn out even if the output is shorted. 6. There are two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in; 7. When used as a lithium battery charger, you can set the float voltage and charge current, and the indicator light indicates whether it is charging or is already full; 8. The onboard voltage and ammeter can be self-calibrated, and there will never be any inaccuracies!
