Input voltage must be 1.5 V higher than the output voltage, no boost 2. Do not reverse the input and output interface 3. Keep output under 2.5A (or 10W) and use a heat sink when for a long time working4. The factory settings stay a high voltage, you may need to contrarotate the screw on blue potentiometer about 7-15 circles before the output voltage changes Specifications: - Type: DC-DC buck converter - Input voltage: DC 3.2V - 35V - Output Voltage: DC 1.25V - 30V (adjustable) - Output Current: 3A (max.) - Output Power: 15W (max.) - Conversion Efficiency: 92% (max.) - Switching Frequency : 65KHz - Rectification: non-synchronous rectification - Module property: non-isolated buck module - Operating Temperature: -45℃ to +85℃ - Load Regulation: ± 0.5% - Voltage Regulation: ± 2.5% - Size(L x W x H): 45*23*14mm / 1.77*0.91*0.55inch - Weight: 14g Package List: 6x DC to DC Buck Converter Module Review: Used as a DC input Power supply regulator Review: Awesome ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076H3XHXP | | Brand | Valefod | | Brand Name | Valefod | | Current Rating | 3 Amps | | Customer Reviews | 4.4 out of 5 stars 900 Reviews | | Item Dimensions D x W x H | 23D x 45W x 14H Millimeters | | Item Weight | 14 Grams | | Manufacturer | Valefod | | Maximum Frequency | 65 KHz | | Minimum Frequency | 50 Hz | | Model Number | VA-HW-411 | | Part Number | VA-139-52 | | Power Source | Corded Electric | | Power Source Type | Corded Electric | | Product Dimensions | 23D x 45W x 14H Millimeters | | UPC | 889328049201 | ## Product Details - **Brand:** Valefod - **Power Source:** Corded Electric - **Product Dimensions:** 23D x 45W x 14H Millimeters - **Current Rating:** 3 Amps - **Item Weight:** 14 Grams ## Images ![Valefod 6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step Down Module - Image 1](https://m.media-amazon.com/images/I/71lLCBgYohL.jpg) ![Valefod 6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step Down Module - Image 2](https://m.media-amazon.com/images/I/616do91Hk6L.jpg) ![Valefod 6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step Down Module - Image 3](https://m.media-amazon.com/images/I/6151S6yfoCL.jpg) ![Valefod 6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step Down Module - Image 4](https://m.media-amazon.com/images/I/61OoDgqEJDL.jpg) ![Valefod 6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step Down Module - Image 5](https://m.media-amazon.com/images/I/61j+j2icj-L.jpg) ## Questions & Answers **Q: Is the output a percentage of the input, or a constant? If I have 20 v in, adjust to 5v out; input goes to 30v will output be 5v or 7.5v?** A: Output voltage is set by the variable resistor and stays independent of the input voltage ( as long as the input voltage stays a few volts above the output voltage). If the input voltage dips, the output voltage will also dip. **Q: What are the dimensions of this voltage regulator?** A: 43 x 21 x 12 mm using caliper on actual product. **Q: Is there any datasheet / CAD model that shows mounting hole dimensions and location of the mounting holes?** A: None I know of just trace it out with standoff mounted in your project case and use dremel dril bit kit according to thread hole size. Good-luck. **Q: Does anyone have the dimensions of mounting holes, and voltage input/output locations?** A: Mounting holes will work with standoff kits on amazon nylon or etal with screws .
