Many customers may ask: What is the difference between UPS uninterruptible power supply and regulated power supply? Today, I will share with you the differences between the two.To clarify the difference between the two, we first need to understand what UPS is and its working principle.

       UPS uninterruptible power supply(Uninterruptible Power Supply)It is an uninterruptible power supply that contains energy storage devices. Mainly used to provide uninterrupted power supply for some devices that require high power stability. When the mains power is normal, UPS is rectified by the mains power, providing DC voltage to the inverter for operation, and the inverter provides AC power to the load. At this time, UPS is an AC mains voltage stabilizer, and DC power is also charged to the internal battery. In case of abnormal power supply, the inverter is powered by the battery to continue supplying AC power to the load, maintaining normal operation of the load and protecting the load's software and hardware from damage. Since the inverter is always in operation, the output will not be interrupted. Generally used in computer and digital information system applications. Load with high power supply quality is required, with important emphasis on inverter switching time, output voltage, frequency stability, purity of output waveform, and no various interferences. Its characteristics are stable voltage and frequency, high output accuracy; Fast conversion time, 0-10ms; Usually, dual conversion circuits supply power, and only switch to bypass power when the inverter malfunctions or is overloaded, resulting in low energy utilization.

       Stabilized Voltage Supply is an electronic device that can provide stable AC or DC power to a load, including two categories: AC stabilized power supply and DC stabilized power supply. When the voltage of the power grid fluctuates instantaneously, the stabilized power supply can quickly respond within 10-30ms, compensate for the voltage amplitude, and stabilize within ± 2%. The stabilized power supply can automatically adjust the output voltage to stabilize voltage equipment with large fluctuations and non-compliance within the set range, providing rated voltage for various electrical equipment and ensuring that electrical equipment operates at normal voltage. In addition to voltage stability, a regulated power supply 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 may experience faults due to low voltage resistance. The surge resistant components of the voltage stabilizing power supply can effectively suppress them. Stable voltage power supplies also have the functions of isolating conducted electromagnetic interference and lightning protection, and are 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 to 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.
