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)
