What is the difference between a not inter ups disconnected power supply and a stabilized power supply?
I believe that those who are engaged in the production or sales of UPS may have encountered the problem of stabilized power supply more or less. Many new friends have this question. What is the difference between an uninterruptible power supply and a regulated power supply? Nowadays, UPS manufacturers share the difference between UPS and regulated power supply.
In order to understand the difference between ups and regulated power supply, we first need to know what ups are. Next, we will explain how ups works.
When the grid voltage is normal, the UPS stabilizes and supplies power to the load. At the same time, the UPS charges the batteries in the machine as a power source. When the grid voltage is abnormal, the UPS can maintain the power supply to the load by converting the DC power from the battery to AC power through the inverter. It can be seen that UPS can realize automatic switching between grid power and battery power to ensure uninterrupted power supply to the load.
As for the appropriate switching time, it depends on the application of the ups. When used on ordinary computers, the switching time is acceptable within 10ms; when used on precision communication equipment or computer equipment, power failure is not allowed. Therefore, zero switching is required at this time. Therefore, when purchasing a UPS, you need to know the occasion for which you are using the UPS.
Different from the regulated power supply, the regulated power supply can automatically adjust the output voltage, so that the fluctuation is large, does not meet the requirements of the voltage equipment stabilized in the set range of values for a variety of electrical equipment to provide the rated voltage, to ensure that the electrical equipment in the normal voltage work. It can be seen that the voltage stabilized power supply has the following functions
First, stabilize the voltage:
When the grid voltage fluctuates instantaneously, the voltage stabilized power supply can respond quickly within 10-30ms to compensate for the voltage amplitude, stabilized within ±2%.
Second, multi-function comprehensive protection:
In addition to voltage stabilization, the regulated power supply can also play a protective role in over-voltage, under-voltage, phase loss, short-circuit overload and so on. When there is a high amplitude narrow pulse width spike pulse in the power grid, electronic components due to low voltage tolerance and capacitive failure, regulated power supply anti-surge components can play a good role in suppressing.
In addition, the regulated power supply also has the function of isolating the conductive electromagnetic interference and lightning protection, widely used in data equipment. As we can see, the difference between the ups and the regulated power supply is still obvious. the main function of the UPS is to provide power for the load. The main function of voltage stabilized power supply is to stabilize the voltage so that the power supply equipment can work normally under the rated voltage. Above is the share of ups manufacturer for you. I hope it can help you.
