Dimming Operation
■ Instruction:
1. Confirm if the rated input voltage of the power supply is within the range of market voltage before use.
2. Pay attention to the distinction between the input and output lines of the power supply to avoid power damage or unnecessary safety accidents caused by connecting the reverse line.
3. The power supply cannot be stacked for installation (placement), and the installation distance between the power supply and the power supply should be greater than 10cm. Multiple power supplies should be installed in a narrow space, and the environmental temperature should be less than 55 ℃ during use; For example, distribution boxes, etc.
4. In order to extend the service life of the power supply, the power supply should be installed in an environment that is conducive to heat dissipation as much as possible;
5. As the ambient temperature increases, the power used by the power supply gradually decreases, and the lifespan of the power supply also gradually shortens.
6. Do not use under abnormal loads: Overloading can cause damage to the power supply, and extremely light loads can cause the power supply to malfunction.
7. To ensure safety and reduce interference, please ensure that the grounding wire is reliably grounded
8. If the LED driver do not work normally, pl. don’t maintain privately, but contact us: sales1@smartselectronics.com Or take a phone call: 0086-595-27256889
