Long press (more than 3second) to restore default settings. 2. IN/OUT Button: Short Press to switch display input voltage or output voltage. Long press to switch display output current or output power. 3. ON LED: Green LED, Output indicator. 4.CC LED: Red LED, Constant current output indicator. when the load current reaches the set current , CC indicator will turns ON. Parameters: Input voltage range: DC 5.5-30V Output voltage range: DC 0.5-30V Output current: 0-3A (natural cooling), Max.4A (enhance heat dissipation) Output power: 35W (natural cooling), Max.50w (enhance heat dissipation) Voltage display resolution: 0.05V Current display resolution: 0.005A Conversion rate: about 88% Soft start: Yes, (a large power load module may fail when it is started) Working frequency: 180KHZ Protection:Input reverse connection protection, Output stop the current from feeding back protection,Output short circuit protection, Input undervoltage protection. The diameter of mounting hole: 4mm Attention： 1.IN- and OUT- must not be short circuit, otherwise the CC function will be invalid. 2. Please ensure that the power of the power supply is greater than the power required by the output load! 3.The input voltage should be over 8V ,if Full-load output . 4.when the input voltage is 5V, you can normally achieve buck-boost, but the voltage and current measurement is inaccurate; less than 4.7V, under voltage protection will be activated ## Features - Precise Button-Controlled Adjustment – No potentiometer required! Easily fine-tune voltage using intuitive buttons for more precise control and hassle-free operation. - Step-Up & Step-Down Conversion – Supports both boost and buck functions, allowing seamless voltage regulation from DC 5V~30V input to DC 0.65V~30V output, perfect for versatile applications. Max output power is 35W, with enhance dissipation, it can reach 50W. - Smart LCD Display – Real-time monitoring of input and output voltage, output current and output power, making it ideal for lab testing, DIY electronics, and power management. - CC & CV Modes – Features constant voltage (CV) and constant current (CC) regulation, making it suitable for battery charging, LED drivers, and solar charging setups. - Safe Protection: with reverse connection protection at input and with anti-backflow at output terminal, so there is no need to add an anti-backflow diode when charging the batter - Note: Its recommended that the input voltage should be higher than 7V. - Warranty: Product covers 1 year warranty.

Can this deliver the low current?** A: Yes. It can deliver 0 to 30 volts & 0 to 5 Amps . This can be set & it will be constant. **Q: can u provide circuit diagram to charge my 7.2 ah lead acid battery ?** A: You can not charge batteries using this, as this provide fix outout voltages (battery needs varying voltage in charge cycle). If you want to charge batteries you can use our solar charge controller, by providing DC voltage instead of connecting solar panel. **Q: can i use this to charge 12V Li-ion battery ?** A: It will provide fix output voltage.... However battery chargers usually have variable voltages based on charging percentage. So not recommended. **Q: can I connect variable current loads to this like an android tablet without battery?** A: Yes you can do so ## Frequently Bought Together - amiciSmart Buck Boost Converter Display, Buck-Boost Board DC 5-30V to DC 0.6-30V Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module - Robotbanao Dual LED 0.28” Red-Blue Display Digital Voltmeter (0-100V) and Ammeter (10A)-LED Display-Digital Voltmeter Ammeter-Voltage Current Tester - Superb Technologies CT-VA 100V 10A Dc Dual Led Red and Blue Digital Voltmeter Ammeter Monitor Panel --- ## 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.ni/products/137332129-buck-boost-converter-display-buck-boost-board-dc-5-30v](https://www.desertcart.ni/products/137332129-buck-boost-converter-display-buck-boost-board-dc-5-30v) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-10-10*
