LED IC isolation constant current drive power transformer external built-in 3W5W7W9W12W24W36W downlight spot lamp ballast

LED IC isolation constant current drive power transformer external built-in 3W5W7W9W12W24W36W downlight spot lamp ballast

The drive power adopts mature scheme, patch and manual plug-in to ensure high stability of the product. The product has a high constant current accuracy, and the output voltage will be automatically adjusted according to the lamp bead voltage you receive (if eight 3.2v lamps are connected, the output voltage will be automatically adjusted to 25.6v). This circuit has overcurrent protection, short circuit protection and open circuit protection. The power supply has a bad chance of about 5 in 1000. Wide applicability, suitable for bulb lamp, spot lamp, projection lamp, etc.

Product features:
1. Features of ultra-small size design, low noise and safety;
2. Adopt high efficiency, low consumption and stable imported chips to achieve the purpose of energy saving and environmental protection;
3. Constant output current. It ensures the security and stability of LED, improves the light efficiency of LED, and reduces the light fading
4. Overload, overvoltage, short circuit and overcurrent protection ensure the safety of power supply;
5. Wide voltage alternating current input, no need to distinguish positive and negative poles;
6. The output terminal is red positive pole and white negative pole.

Special reminder: bare board built-in type, use must be wrapped in a layer of insulation glue outside the power supply, to prevent short circuit and leakage!
