5.1. Reliability

MTBF

When working at rated load and ambient temperature is 25 ° C, the theoretical average time of failure of this constant voltage power supply is 10,000 hours, and the average time of failure of actual life test exceeds 10,000 hours.

6. Protection

6.1. Temperature protection: 85 degree protection is set inside the product, and it will recover automatically when the temperature drops.

6.2. Over-voltage protection: When the product fails, the output voltage reaches 130% of the rated voltage, the internal components of the product breakdown, and there is no output, thereby protecting the safety of external equipment.

6.3. Short-circuit protection: When the output is short-circuited, the product will perform protection and isolation mode, and the average input power is less than 20W.

6.4. Overcurrent protection: When the current reaches 10A-12.5A, the product protection has no output.

9. Matters needing attention

9.1. It should be easy to dissipate heat during installation and should not be installed near the heat source;

9.2. Avoid working under abnormal conditions for a long time, such as overload, short circuit, work in the non-operating voltage range, etc .;

9.3. When installing and using, please note that the working voltage of the lamp should be consistent with the output voltage of the power supply, and the working current of the lamp cannot exceed the rated maximum output current of the power supply;

9.4. Wiring connections must be firm and reliable, and insulated to prevent leakage.
