Tips: What is the voltage regulation test in switching power supply?

Line regulation test, which means the rate of change of the output voltage with the input AC voltage when the power supply has a certain load. What is investigated is that when the input AC grid voltage varies within a certain range, the output voltage of the power supply cannot have too much jump. Generally set at ±2%-±5%.

Existing reviews of 15V DC 10A 300W Switching Power Supply

Good quality power supply

This switching power supply is compact but powerful. It fits easily into my equipment cabinet and provides a steady 15V output without noticeable fluctuation. After several weeks of use, everything is still working smoothly.

This is a great buy.

I am using this to power a variety of equipment that only needs about half the rated power. Nice package, Steady DC voltage, great regulation, even at quickly varying current. Very quiet too. Overall, so far, so awesome. I would recommend it to anyone.
