About this item

he LED bulb driver is designed to power a 9-watt LED bulb, providing efficient illumination while minimizing energy consumption. 2. **Input Voltage Range:** The driver is compatible with a wide input voltage range, typically around 100V to 300V AC, ensuring compatibility with various power supply systems. 3. **Output Voltage and Current:** The driver generates a stable output voltage typically around 12V to 18V DC, with a constant current output designed to suit the LED specifications and ensure consistent brightness and performance. 4. **Efficiency:** The driver is built with high-efficiency circuitry, often exceeding 85% efficiency, to minimize power losses during the conversion process. 5. **Surge Protection (4KV):** The driver is equipped with surge protection capabilities to safeguard the LED bulb against voltage spikes caused by lightning or other electrical disturbances. The surge protection rating of 4KV (4000 volts) ensures that the driver can handle substantial voltage surges without damaging the LED components. 6. **Voltage Protection (440V):** The driver features voltage protection that prevents damage to the LED bulb in cases where the input voltage exceeds a certain threshold, typically set around 440V. This protection is crucial for maintaining the longevity of the LED bulb and the driver itself. 7. **Constant Current Regulation:** The driver employs a constant current regulation mechanism to ensure that the LED receives a consistent and appropriate current, regardless of variations in input voltage. This feature contributes to stable brightness and extends LED lifespan. 8. **Short Circuit Protection:** The driver includes short circuit protection to automatically shut off the output current in case of a short circuit, preventing damage to the driver, LED components, and the connected power system. 9. **Overload Protection:** To prevent overheating and potential damage, the driver incorporates overload protection. If the load connected to the driver exceeds its rated capacity, the driver will take measures to safeguard itself and the LED bulb. 10. **Thermal Management:** The driver is designed with thermal management mechanisms such as heat sinks or temperature sensors to regulate its operating temperature. This ensures optimal performance and prevents overheating that could negatively impact the driver's efficiency and lifespan. 11. **Electromagnetic Compatibility (EMC):** The driver is designed to comply with electromagnetic compatibility standards, minimizing electromagnetic interference that could affect other electronic devices in the vicinity. 12. **Isolation:** The driver often includes isolation components to electrically separate the input and output sides, providing safety and preventing potential hazards. 13. **Form Factor:** The driver's compact and lightweight design allows for easy integration into the LED bulb's housing while maintaining space efficiency. 14. **Certifications:** The driver may have certifications such as CE, RoHS, and UL, indicating compliance with international safety and environmental standards. It's important to note that the technical details provided above are general specifications and features typically found in LED bulb drivers with surge and voltage protection. Actual specifications may vary based on manufacturer, model, and design considerations.
