Parameters Input Voltage: DC 6-30V Output Voltage: DC 0.5-30V adjustable Output Current: 4A (max), adjustable, recommended to use within 3A. NOTE: If the output current or power is more than 2.5A or 35W, you’d better enhance the heat dissipation. Output Power: 60W (max), recommended to use within 50W. NOTE: Please reduce the power when the difference between input and output voltage is large. Operating Temperature: -20~+70℃ NOTE: Pay attention to the temperature of the power tube when using this module, please strengthen heat dissipation if it exceeds 70℃. Wiring: Terminals or solder terminals; VIN means input; VOUT means output. Protections Short circuit protection: Yes (currently constant current value) Over temperature protection: Yes (automatically turn off the output if over-temperature) Tips: There is an additional fan opening on the bottom of the module shell, which can be used to add a fan. Input reverse polarity protection: Yes Output anti-backflow: Yes Voltage Calibration If you find that the measuring values are not accurate, please do as follow: In the condition of power off, hold press the “SET” button and power on to enter the voltage calibration mode, at this time the LCD screen starts to flash. Then release the “SET” button, press the “SET” button to increase voltage value while press the “ENT” button to reduce, till the input voltage value is correct. e.g. If input voltage is 12.65V, adjust the voltage value to 12.65V. It will automatically be saved after 2 seconds, then power off the module to finish calibrating. Package includes: 1 x Boost Buck Converter Module; Components for the case (Nylon post *8; Screw *8; Acrylic board *2) Review: Works Great!!! - Works Great!!! ## Features - Parameter --- Input voltage: DC 6-30V; Output voltage: DC 0.5-30V; Output current: 4A (max), adjustable, recommended to use within 3A; Output power: 60W (max), recommended to use within 50W. Note: This product is intended solely for DC-DC loads that do not incorporate computers or laptops. - Easy to Read LCD Display --- The buck boost board is designed with a large clear digital LCD display on which shows both voltage and current value simultaneously. Which is easy to read and can help the user easily monitor the output voltage, then largely enjoy their DIY work. - Application --- This voltage step up and down module can be used as a normal boost buck converter module with over-current protection, a battery charger, a high-power LED constant current driver module, etc. - Features --- Constant current/voltage mode; Voltage calibration calibration; USB output; Protective case; Short-circuit protection; Over-temperature protection; Input reverse connection protection. You can find the PDF Instructions on this page -- Product information -- Product guides and documents -- User Manual [PDF]. - NOTE --- 1). Constant current adjustable means that CC mode only works when the actual load output current is greater than the setting one, otherwise it will work in a constant voltage state, not the current is adjusted to 2A, then it will become 2A for any load being connected. And if the CC value to be adjusted is small, adjust “ADJ-I” counterclockwise a few more times to change. 2). The case is packaged disassembly to avoid damage during transit. It needs to be manually installed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08RBXCJCF | | Best Sellers Rank | #33,679 in Computers ( See Top 100 in Computers ) #205 in Computer Power Supplies | | Brand | DROK | | Brand Name | DROK | | Current Rating | 4 Amps | | Current rating | 4 Amps | | Customer Reviews | 4.3 out of 5 stars 2,089 Reviews | | Item Dimensions D x W x H | 4.3D x 7W x 2.7H centimeters | | Manufacturer | DROK | | Minimum Frequency | 50 Hz | | Model | DROK-BB630V | | Mounting Type | PCB Mount | | Mounting type | PCB Mount | | Power Source | Dc Power Supply | | Power source | Dc Power Supply | | Product dimensions | 4.3D x 7W x 2.7H centimeters | | Specification Met | CE | | Specification met | CE | ## Product Details - **Brand:** DROK - **Current rating:** 4 Amps - **Mounting type:** PCB Mount - **Power source:** Dc Power Supply - **Product dimensions:** 4.3D x 7W x 2.7H centimeters ## Images ![Buck Boost Voltage Regulator, DROK DC 6-30V to DC 0.5-30V 5V 12V 24V Adjustable Voltage Converter, 4A 60W Power Supply Step Up Down Transformer Board Module with USB Port Case LCD Display Volt Am - Image 1](https://m.media-amazon.com/images/I/71MTpyz4KyL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐ Works Great!!! *by M***R on 6 August 2025* Works Great!!! ## Frequently Bought Together - DROK Buck Boost Voltage Regulator, DROK DC 6-30V to DC 0.5-30V 5V 12V 24V Adjustable Voltage Converter, 4A 60W Power Supply Step Up Down Transformer Board Module with USB Port Case LCD Display Volt Am - Adjustable Voltage Regulator, DROK DC to DC 5.3V-32V to 1.2V-32V 12V Power Supply Module, 12A LCD Step Down Volt Transformer 160W CC CV Buck Converter Reducer - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## 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.com.cy/products/288894038-buck-boost-voltage-regulator-drok-dc-6-30v-to-dc](https://www.desertcart.com.cy/products/288894038-buck-boost-voltage-regulator-drok-dc-6-30v-to-dc) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
