Dual Display 3A Step Down Power Supply Buck Converter Adjustable LCD Step-down Voltage Regulator DC-DC 5-23V To 0-16.5V

Module Performance and Features:

- Equipped with terminal blocks, allowing easy use without a soldering iron.

- Input voltage: 5~23V (maximum 23V, recommended to use within 20V), with reverse connection protection. (The input voltage must be at least 1V higher     than the output voltage.)

- Adjustable output voltage range: 0V～16.5V (continuously adjustable), with automatic saving of the last set voltage.

- Peak current: 3A (recommended to use within 2A). Accuracy: 1%, minimum display: 0.01A. It will heat up significantly when the current exceeds 2A; please find your own solutions for heat dissipation.

- High conversion efficiency: up to 95% (efficiency is related to input voltage, output voltage, current, and voltage difference).

- Load regulation rate S（I）≤0.8%, voltage regulation rate S（u）≤0.8%.

- Size: 62mm44mm18mm.

- Weight: 45g.

Product Highlights:

- Exquisite acrylic shell.

- The display adopts an STN LCD screen, which can show voltage and current simultaneously. With a blue background and white characters, it is clear from any wide-angle view, outperforming similar products that use nixie tubes. Ordinary nixie tubes tend to have segment failures after a period of use, but this product is free from such issues.

- Pioneering button-based voltage adjustment: the left button decreases voltage, and the right one increases voltage. A single press allows fine adjustment of 0.04V, while pressing and holding for 1 second enables quick voltage adjustment. The buttons can withstand 100,000 presses, making voltage adjustment more convenient and faster compared to similar potentiometer-based products.
