DROK 20pcs LED Display LM2596 Buck Converter - DC to DC Buck Converter Adjustable Voltage Regulator 4-40V to 1.25-37V
- Robust Protection Built-in safeguards include reverse connection protection, overheating protection, and short-circuit protection provide stable and reliable DC-DC step-down conversion.
- DC Voltage Regulator Adjustable Turn the potentiometer counterclockwise with a mini screwdriver and to step down output voltage, clockwise to step up. Please make sure the input voltage is at least 1.5V higher than output voltage to ensure stable output.
- Precision Calibration Conserve power by turning off the display (long-press 1-4s); reactivate instantly with a short press. Achieve higher accuracy (0.5V adjustable range) via advanced calibration mode (long-press >4s) for both input and output voltages independently. Settings are saved permanently.
- Dual Voltage Monitoring & Display Features a built-in voltmeter with 0.1V accuracy (4-40V range). Note: Voltmeter activates only when input voltage exceeds 4V. Clearly indicates input (IN) or output (OUT) voltage via LED lights and digital display;
