1. All parameters 230VAC input, rated load, ambient temperature 25 ℃, measured under conditions of 70% humidity;

2. Accuracy: includes set up tolerance, line regulation, load regulation and so on;

3. Ripple Test: 30cm long strands connect the power supply and the load, the load side and 0.1u and 47u capacitor to 20MHz oscilloscope measured at the load end;

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

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

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)
