## Description

Button/Potentiometer/LED introduction: 1.ON/OFF Button: Short Press to select whether output . 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. CV Potentiometer: Adjust output voltage. clockwise，Increasing. 4. CC Potentiometer: Adjust output current. clockwise，Increasing. 5. ON LED: Green LED, Output indicator. 6.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

Review: Definitely Deserve 5 Stars. Amazing Amici team and Amazing desertcart. - Amazing product. It's quite precise and extremely useful voltage regulator. I used it to make a mini UPS for my internet modem which used to restart everytime there was a fluctuation or power disruption thereby wasting precious 15 minutes by the time the connection used to re-establish. It has proven extremely useful as a variable voltage battery Bank and a variable dc voltage source. I thank the Amici team and desertcart for quick delivery and prompt response with any questions or concerns. I definitely recommend the seller and the product. In fact, I'll be buying 3 more of the same product asap. Kudos to the Amici team and desertcart. 5 stars.
Review: Defective product, Defective even after replacing! - I got defective product! When I opted for replacement then they took the product and delevered it back without even reparing it! Please don't buy!

## 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.

## Questions & Answers

**Q: My aplication needs constant current at 25 mAmp (0.025 Amp) at 30 volts. 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

### ⭐ Defective product, Defective even after replacing!

### ⭐⭐⭐⭐ nice product. bad packaging
*by M***E on 28 December 2020*

Lost a star for poor packaging. The board was just put into a plastic bag along with an unattached heat sink and delivered. The heat sink would scratch against the delicate electronics and display on the way. I did not get a cardboard box like some pictures show. Maybe I got a piece returned by someone. The product is really good. It works nicely. Unique smart design. It would have been good to get regular potentiometers though.
