What is the difference between uninterruptible power supply and regulated power supply?
I believe that friends who are engaged in UPS production or sales may encounter more or less problems with regulated power supplies. Many new friends have this problem. What is the difference between uninterruptible power supply and regulated power supply? Today, UPS manufacturers share the differences between UPS and regulated power supplies.
In order to understand the difference between UPS and regulated power supply, we first need to know what UPS is. Next, we will explain how ups work.
When the grid voltage is normal, the UPS supplies power to the load after stabilization. At the same time, the UPS will also charge the battery in the machine as a power source. When the grid voltage is abnormal, the UPS can convert the battery's DC power into AC power through the inverter to maintain power supply to the load. It can be seen that UPS can realize automatic conversion between grid power and battery power to ensure uninterrupted load power supply.
As for the appropriate switching time, it depends on the application of ups. When used on ordinary computers, the switching time is acceptable within 10ms; when used on precision communication equipment or computer equipment, power outages are not allowed. Therefore, a zero switch is required at this time. Therefore, when purchasing a UPS, you need to know where you will use it.
Different from the regulated power supply, the regulated power supply can automatically adjust the output voltage to stabilize the voltage equipment with large fluctuations and unqualified voltage within the set range, provide rated voltage for various electrical equipment, and ensure that the electrical equipment operates at normal voltage. Next work. It can be seen that the regulated power supply has the following functions
1. Stable voltage:
When the grid voltage fluctuates instantaneously, the regulated power supply can respond quickly within 10-30ms, compensate the voltage amplitude, and stabilize it within ±2%.
2. Multifunctional comprehensive protection:
In addition to voltage stability, the regulated power supply can also protect against overvoltage, undervoltage, phase loss, short circuit overload, etc. When spike pulses with high amplitude and narrow pulse width appear in the power grid, electronic components are susceptible to failure due to low withstand voltage. The anti-surge components of the regulated power supply can play a very good role in suppressing them.
In addition, the regulated power supply also has the functions of isolating conducted electromagnetic interference and lightning protection, and is widely used in data equipment. It can be seen that the difference between UPS and regulated power supply is still obvious. The main function of UPS is to provide power to the load. The main function of a regulated power supply is to stabilize the voltage so that the power supply equipment can operate normally at the rated voltage. The above is the share provided to you by the ups manufacturer. I hope it helps you.
