Featuring a built-in digital voltmeter, flexible connection options, and a high-frequency 400 kHz switching regulator, it delivers up to 4A output current with high efficiency. Ideal for professionals needing reliable, customizable voltage regulation in industrial and DIY applications. ## Description Specifications: Input voltage: 4.5V-32V. Output voltage: 5V-35V (adjustable). Max. Output current: 4A. Efficiency: Output rib: Switch frequency: 400 kHz. Operating temperature: -40 °C to +85 °C. Size: approx. 66 x 36 x 14 mm / 2.59 x 1.41 x 0.55 inches. Instructions: 1. For the first time, the standard display input voltage and the input indicator in lights. Press the button, then the output voltage and output indicator. Hold the button switch for more than 4 seconds and enter the voltage measurement error calibration function, display in lights (input voltage calibration) and displays the calibration value (default value 0.0). Lights up (output voltage calibration) and the adjustment of the inputs after setting the setting calibration. To turn off voltmeter. Voltmeter is switched on when the switch is switched off. ## Features - Convenient switching: integrated digital voltmeter with a measuring range of 5 V - 35 V. Simply touch the button to switch between input or output voltage measurement, and the corresponding indicator light lights up to visually display the current measurement object. Even if the power supply is switched off or restarted, the final settings can be saved - Multiple connection methods: the input and output terminals are equipped with thread connectors, which can easily connect wires without soldering, while maintaining soldering pads to support soldering, which meet different operating habits and connection requirements - Power output: the second generation switching voltage regulator with a built-in vibration frequency of 400 kHz is used, which has low current consumption and high efficiency. The maximum output current can reach 4A, and it is recommended to work with a current of about 2A. If it exceeds 2A, please install heat sink to improve stability - Wide application: input voltage 4.5V-32V, output voltage 5V-35V adjustable, suitable for various power scenarios such as batteries, current transformers, adjustable voltage regulators and industrial equipment, which easily achieve the voltage conversion from 9V to 12V, 12V to 18V, 18V to 24V - Intelligent calibration: press and hold the button for more than 4 seconds to enter the voltage measurement error calibration mode, calibrate the input and output voltages separately, the indicator light IN lights up (input voltage calibration), the display flashes to display the calibration value, and the turn off can save the calibration value ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0FDWFPMQL | | Manufacturer | Watris Veiyi | | Manufacturer reference | Watris Veiyipn09rihxmw | | Package Dimensions | 7 x 5 x 2 cm; 24 g | ## Images ![Watris Veiyi Voltage Regulator Adjustable, DC-DC 4.5V-32V to 5V-35V Converter, Step Up Module Boost Converter, Power Supply - Image 1](https://m.media-amazon.com/images/I/61b5tMno-kL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/884752066-watris-veiyi-voltage-regulator-adjustable-dc-dc-4-5v-32v](https://www.desertcart.no/products/884752066-watris-veiyi-voltage-regulator-adjustable-dc-dc-4-5v-32v) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-16*
