In addition to voltage stability, the regulated power supply can also play a protective role in overvoltage, undervoltage, phase loss, short circuit overload and other aspects. When the spike pulse with high amplitude and narrow pulse width occurs in the power grid, the electronic components will fail due to the low voltage resistance, and the anti-surge components of the regulated power supply can play a very good role in inhibiting.

In addition, the regulated power supply also has the function of isolating conducted electromagnetic interference and lightning protection, which is widely used in data equipment. Thus, the difference between ups and regulated power supply is still obvious. The main function of the UPS is to provide power for loads. The main function of the regulated voltage supply is to stabilize the voltage, so that the power supply equipment can work normally under the rated voltage.
