Notes
|
1. All parameters are measured at 220 V AC input, rated load, ambient temperature 25 ° C, humidity 70%;
2. Accuracy: including setting error, line regulation, load regulation rate;
3. Ripple test: 30cm long wire with the power and load, load and 0.1u and 47u capacitance to 20MHz
oscilloscope measured at the load side;
4. Line regulation: the rated load conditions, the input voltage changes from low to high measured;
5. Load regulation: Measured output is measured from 0% load to 100% load change.

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)
