10. FUSE PROTECTION

 

 

The Fuse inside the power supply shall open when the AC input current is over the rated current of 

fuse. This Fuse protection will cause switching power supply to fail. 

10.1 SAFETY

 

 

The power supply shall compliance with the following Criterion:

 

 

1)      UL60950/UL60065 

 

2)      EN60950/EN60065 

 

3)      GB4943-19950/GB8898-2001

11. CONFIGURATION & GENERAL PRECAUTIONS 

 

 

Relative Humidity: ≤ 80% 
Storage Temperature: -10 ~ + 60

℃ 

Operation 

Temperature: 0 ~ +40

℃  

 

Keep the board away from conductor, static electricity and water when it is working. 

 

Don’t push or pull the connectors when the board is working. 

 

Clean the board with soft dry cloth when it’s dirty.
