상품 특징

• 【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; toggles with a single button press. Remembers your last viewed setting after power cycles.
• 【High-Efficiency 3A Output】 Delivers a strong 3A continuous output current (recommended 2A for optimal thermals). Utilizes a 150kHz 2nd-gen switching regulator for minimal power loss and high conversion efficiency. Adequate heatsinking is advised for loads above 2A.
