FAQ

1.How to choose a switching power supply?

To increase the reliability of the smps, like dual output switching power supply, we suggest users choose a unit that has a rating of 30% more power than actual need. Make sure that the model qualifies for the safety standards and EMC regulations you need.

2.What are switching power supplies?

Dual output switching power supplies input a commercial AC power supply (such as 110 VAC or 220 VAC), uses a high-speed semiconductor switching process to convert the input to high-frequency electric power.
