Note

1. All parameters are measured at 230VAC input, rated load, ambient temperature 25 ℃, humidity 70%;

2. Accuracy: including setting error, line adjustment rate, load adjustment rate, etc.;

3. Ripple test: connect the power supply and load with a 30cm long twisted wire, with 0.1u and 47u capacitors on the load side and 20MHz oscilloscope on the load side;

4. Line regulation: at rated load conditions, the input voltage changes from low to high measured;

5. Load regulation: the measured output from 0% to 100% load change load measured;

6. When the loadis more than 400w,itneed to increase at least 10CFMforfan cooling.

FAQ



Q1. Can I have a sample order for power supply?
A1: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.

 

Q2: Do you accept OEM/ODM for the switching power supply?
A2: Yes. we do.

 

Q3:How about the quality?
A3:We have the better professional and experienced engineers team and strict QA and QC system.Repair rate under 0.1%~0.2%

 

Q4:What is PFC?
A4:PFC stands for Power Factor Correction. The purpose of PFC is to improve the ratio of apparent power and real power. The power factor is only 0.5~0.7 in non-PFC models. In PFC models, the power factor can reach above 0.9. The calculation formulas are as below: 
Apparent Power=Input Voltage x Input Current (VA) 

Real Power= Input Voltage x Input Current x Power Factor (W)
