FAQ

How to choose our power supply?                                                                                        

 

1. Single output

To determine the power after the output voltage is decided. The power range of our switching power supply is 10W to 1500W, output voltage from 3V to 220V DC. If the requirement is 24V, 1A, we can choose S-25-24, and within cost range, retain 10% -20% of the power allowance.

 

2. Multi-output

The multi-output power supply has the main and secondary circuit output. The character of main circuit output is better than the secondary.To ensure the load regulation and so on, every circuit has to be with a certain load. If just using the second circuit, the main circuit has to be matched with corresponding dummy load (more than 0.5A or larger)

Questions for our power supply?                                                                                            

1. When using your power supply, find the shell with voltage, is that normal?

Answer: That is normal. According to the EMI request, the input port and the shell are connected by a capacitor, which causes the voltage on the shell. It’s specified in the IEC standard that the leakage current is less than 3.5mA. It’s safe and won't cause any damage to people.

 

2. When needing 24V voltage, but only 12V power supply at hand, can this work to connect 2 pieces 12W power supply in series?

Answer: It’s workable. We can cut down the cost through that way sometimes.

 

3. Can use S-50W power supply as the charging power supply?

 Answer: Yes. But in order to avoid battery feedback, please be advised use a series diode on the output, and pay attention to the diode heat dissipation.

 

What is the MOQ of our power supply?                                                                                 

 

MOQ: We support sample order.(1~5PCS)

More than 500PCS,can pring Logo on the products.
