What is the difference between UPS power outage and regulated power supply?
I believe that friends who are engaged in UPS production or sales may encounter problems with regulated power supplies to some extent. Many new friends have this problem. What is the difference between an uninterruptible power supply and a regulated power supply? Nowadays, UPS manufacturers share the differences between UPS and regulated power supplies.
To understand the difference between UPS and regulated power supply, we first need to know what UPS is. Next, we will explain the working principle of UPS.
When the grid voltage is normal, the UPS stabilizes and supplies power to the load. At the same time, UPS also uses the battery in the machine as a power source for charging. When the voltage of the power grid is abnormal, UPS can convert the DC power of the battery into AC power through an inverter to maintain power supply to the load. From this, it can be seen that UPS can achieve automatic conversion between grid power and battery power, ensuring uninterrupted load power supply.
As for the appropriate switching time, it depends on the application situation of UPS. When used on a regular computer, the switching time is acceptable within 10ms; When used on precision communication equipment or computer equipment, power outages are not allowed. Therefore, zero switching is required at this time. Therefore, when purchasing UPS, you need to know where you are using it.
Unlike regulated power supplies, regulated power supplies can automatically adjust the output voltage to stabilize voltage devices that fluctuate significantly and do not meet the requirements within the set range, providing rated voltage for various electrical equipment and ensuring that electrical equipment operates at normal voltage. It can be seen that the regulated power supply has the following functions
1、 Stable voltage:
When the voltage of the power grid fluctuates instantaneously, the stabilized power supply can respond quickly within 10-30ms, compensate for the voltage amplitude, and stabilize within ± 2%.
2、 Multifunctional comprehensive protection:
In addition to voltage stability, regulated power supplies can also play a protective role in overvoltage, undervoltage, phase loss, short circuit overload, and other aspects. When high amplitude and narrow pulse width spikes appear in the power grid, electronic components can cause faults due to low voltage resistance, and the surge resistant components of the regulated power supply can effectively suppress them.
In addition, the regulated power supply also has the function of isolating conductive electromagnetic interference and lightning protection, and is widely used in data equipment. From this, it can be seen that the difference between UPS and regulated power supply is still significant. The main function of UPS is to provide power for the load. The main function of a regulated power supply is to stabilize the voltage and ensure that the power supply equipment operates normally at the rated voltage. The above is the share provided by UPS manufacturer for you. I hope it can help you.
