Feature: 1. Come with automatic protection functions such as overcurrent, overvoltage, overheating, short circuit and so on, use at ease. 2. The built‑in protector automatically cuts off the circuit when the protected circuit is an unsafe value, and resumes normal operation when the value returns to the normal range. 3. Designed to be potted with organic silica gel, waterproof, dustproof and anti‑vibration, use at ease, bring you more convenience. 4. Comprehensive protection, perfectly suitable for use in various harsh environments, and more stable and reliable to use. 5. Suitable for surveillance cameras, electronic refrigerator, portable DVD, audio, security system, portable tool, printer and so on.

Package List: 1 x Power Regulator Note: 1. In order to ensure the normal operation of the converter within the input voltage range, the input voltage must not be lower than the minimum or maximum input value restricted by the product during use. The input voltage value must be higher than the output voltage value by more than 2V. If there is no voltage difference of 2V, the output The value will be lower, but it will not damage (affect) the use of the converter.2. The input current must be greater than or equal to the required power of the output load device (for example, if the power of the load device needs to be 100W, then the input power must be greater than or equal to 100W). When the converter is in use, the current of the load device should not be greater than the maximum current value that the converter can withstand, and leave as much margin as possible for the converter to ensure that the converter works normally and achieves the highest conversion efficiency.3. The positive and negative poles of the converter cannot be reversely connected during use. Reverse connection may cause damage to the converter. It is recommended to add a suitable fuse to the input terminal during use.4. When there is no load, the chip works in light load mode, and the output voltage may vary within a certain range.
