When you get the product in the first time, please don't use your hands to touch the components, because human static electricity can damage some chips.2. You must make sure that the input voltage is 1.1 times higher than output voltage. Under large current circumstances, pay attention to heat elimination.3. If you use AC-DC converter or transformer coil, please add rectifier (rectifier bridge) and filter (more than 4700uf filter capacitor). If input power supply is unstable, please add LC, L is over 47uf, C is over 2200uf. ## Features - This module has power-down stored function and can store 10 groups preset value.LCD display on the module has the function digital voltmeter and ammeter. - You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power, etc. - The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one. - And it also has the function of extracting quickly two groups stored value. - Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required. ## Images ![Befaith DPS3003 Constant Voltage Current Step-down Programmable Voltage Converter as pictures show 79*43*41mm - Image 1](https://images-eu.ssl-images-amazon.com/images/I/41ZsJoiobQL.jpg) ![Befaith DPS3003 Constant Voltage Current Step-down Programmable Voltage Converter as pictures show 79*43*41mm - Image 2](https://images-eu.ssl-images-amazon.com/images/I/410QLKh8J8L.jpg) ![Befaith DPS3003 Constant Voltage Current Step-down Programmable Voltage Converter as pictures show 79*43*41mm - Image 3](https://images-eu.ssl-images-amazon.com/images/I/51f6IHDiplL.jpg) ![Befaith DPS3003 Constant Voltage Current Step-down Programmable Voltage Converter as pictures show 79*43*41mm - Image 4](https://images-eu.ssl-images-amazon.com/images/I/51r8eJlNJfL.jpg) ![Befaith DPS3003 Constant Voltage Current Step-down Programmable Voltage Converter as pictures show 79*43*41mm - Image 5](https://images-eu.ssl-images-amazon.com/images/I/51pk49rulNL.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.at/products/63633612-befaith-dps3003-constant-voltage-current-step-down-programmable-voltage-converter](https://www.desertcart.at/products/63633612-befaith-dps3003-constant-voltage-current-step-down-programmable-voltage-converter) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-27*
