DC 8-30V to 3.3V 3A Voltage Converter:Efficiently converts a DC input of 12V or 24V to a stable 3.3V output, supporting currents up to 3A. Output Power: 9.9W. Note:The load connected to the output side must not exceed the specified maximum load. Various protections: DC Voltage Converter supports short-circuit protection, over-temperature protection, over-current protection, anti-disconnection protection; small size, ultra-thin, easy to install; dust-proof, moisture-proof, shock-proof and other functions. Support short-circuit protection: when the output is short-circuited, the product stops working without output, and the output can be resumed after troubleshooting. Please pay attention to the correct input, negative reverse connection, will lead to permanent damage to the product. Storage: Store the product in a cool and dry place, avoid contact with corrosive substances, and keep away from fire and heat sources. The product adopts synchronous rectification technology, high conversion efficiency and stable performance.Please note: Do not immerse the product completely in water (the product is not waterproof). Widely used: Voltage Converter is widely used in Motor, LED light strip, monitoring systems, motors, electronic systems, car radios, stereos, buses, minibuses, trucks display, car billboards, solar panels, walkie-talkies, DIY equipment and so on.

Output: White (+) Black (-). Tips： To ensure the product is in optimal working condition, an input voltage of 8-30V is recommended. Precautions： 1. No reverse polarity, power supply has no reverse polarity protection, reverse port will damage the power supply. Please note that the positive and negative polarity of input cannot be interchanged. 2. During operation, the load can not be overloaded, leave space for the power supply to ensure that the power supply works stably for a long time. 3. If the ambient temperature is too high during operation, the power consumption should be reduced accordingly, and the power supply can work stably for a long time under low temperature to ensure normal operation. 4. Do not use it near a heat source (such as fire or heater). 5. Do not connect the input cable to 220V power supply. 6. Do not put the product into fire or heat it. 7. Do not short-circuit the positive and negative terminals of the product with wires or other metal objects. 8. Prohibit non-professionals from disassembling and repairing the product.
