## Description

Product Description DC-DC Step Down Converter, 8-40V to 5V Buck Converter 10A 50W with Fuse Waterproof It is a highly reliable DC-DC Converter,they have the characteristics of wide input voltage, low power consumption, high efficiency and high reliability.We provide different power supply voltage converters for various application equipment. Safety Instructional Manual 1. The load connected to the output end of the converter should not be more than max listed load power, any higher rated load will cause damage to the power regulator. 2. Can not used long time by the MAX. If your device's load is close to MAX power, please select a higher power converter. 3. Please connect the converter and your device according to the wiring diagram provided. Converter Connection Input: red(+) black(-) Output: yellow(+) black(-) Protection: input transient high voltage protection, output over-current protection, chip over-temperature protection.(please note that there is no input short circuit protection and reversed connection protection, please connect wires correctly, or the power may be burnt) Fuse & Safer The transformer is equipped with a fuse, and the fuse will be blown if the voltage is too high, which can reduce the risk of fire or explosion and fully protect the safety of users. IP67 waterproof module DC transforme Better Heat Dissipation. Adopts thermal conductive organic silicone filling and sealing technology is waterproof, moisture-proof, seismic and adapt to a variety of harsh environment. Wide Applications Widely used to golf cart, motor, speaker, GPS, LED car display screen, photo-voltaic power,industrial equipment ect.

Review: Seems to do what I expected. - I've been using this to power a Jetson nano, 2x raspberry pi zero's broadcasting video and 4x encoders and it copes well so far. Had to reduce its size a little but compact and powerful. For my requirements the fuse holder is placed in the wrong place, but removed it and resoldered the leads, just the trick. Very content with purchase
Review: All good. - All work fine.

## Features

- [DC-DC Step Down Converter] This buck converter 8-40V to 5V converts the DC 8-40V into DC 5V. Low power consumption. Voltage input: DC 8-40V, output: DC 5V. Max Current: 10A 50W. WARNING: 1.Please confirm whether the output voltage is correct before use; 2.Please confirm the positive and negative polarity of the power before wiring; 3.Must connect the input negative wire to GND or - before use, or the output volts will not change!
- [With Fuse & More Safer] For the safety of users, our step down converter are equipped with fuses. When the voltage is too high, the current exceeds(15A), the circuit breaks down or is abnormal, the fuse will blow and the transformer will stop working, thereby protecting the electrical appliances. In addition, this can reduce the risk of fire or explosion. Comparing with other ordinary transformers, our products are more advanced and safer. High conversion rate over 96%. longer service life.
