## Description

Parameters： Chip: MP2304 Input voltage: 6~32V Output voltage: 1.5~32V continuously adjustable (Input should be 1.5V higher than output.) Output current: 5A max, adjustable, recommended use within 4.5A. (Over 3A or 35W, please enhance heat dissipation.) Constant current requires an output voltage of above 2V to be adjusted. Current regulation can only be performed in the status of constant current. Output Power: 75W (max), recommended use within 50W. Please reduce the power when voltage difference is large. Operating temperature: -20℃ to +70℃ Operating frequency: 180KHz Conversion efficiency: up to 96% Short circuit protection: Yes (Constant current value set by constant current function) Over-temperature protection: Yes (Automatically shut off the output when overtemp.) Input reverse polarity protection: Yes Output backflow prevention: None. Please add a diode when used for charging. Installation: 8x pillars, 8x 3mm screws Wire Connection: terminal block or soldering terminals; VIN is input; VOUT is output. Dimension: 65.6*40*25mmDisplay Modes: 1). F-0 mode: Display output voltage 2). F-1 mode: Display input voltage 3). F-2 mode: Display input and output voltage alternately 4). USB mode: Display USB output voltage & turn on/off USB outputNote: Output is set as around 20V before leaving factory, if your input is lower than that, please turn potentiometer anticlockwise for at least 10 laps until voltage changes.Package Included: 1x DC Buck Module 4x Copper Cylinder Screws M3*6 4x Double-pass Screws M3*12 8x Roundhead Screws M3*6

## Questions & Answers

**Q: Delivered without instructions -- where can a 'user's manual' be found?**
A: Hi, there is a PDF Instructions on the product page -- Product information -- Technical Specification -- User Manual pdf  
https://images-na.ssl-images-amazon.com/images/I/C1X8DiomGTS.pdf
Hope it could help you.

**Q: Is the usb output fixed or is it adjustable?**
A: It's not fixed. I had it as high as 13.3 volts in my application of the USB connector.  You need to set output to 5v before using any standard usb device.

**Q: In the instructions it says to use a diode if using for charging, where does the diode go?**
A: There are two good answers here; when charging a battery with this converter, a series diode should be placed between this device's output and the battery to prevent the battery from attempting to backcharge this device if this device's output drops below battery voltage.

In addition... if this device is used as a charge controller for a phototaic (solar) panel, a series diode should also be placed between the panel and this device to ensure that this device will never attempt to backcharge the panel.

I suggest the use of a fairly significant Schottky diode for either application.

**Q: Constant output voltage with changing input voltage? If I have solar panels as an input with a chaning voltage (+-. 5V) will this affect the output?**
A: Check the limit of input shown in the instruction manual.  This unit will regulate voltage or amperage, but not both at the same time.

Great little buck converter, comes disassembled as acrylic is fragile but assembly is extremely simple and while a short guide would be nice it's not worth the waste of paper.
