The utility input AC power into a regulated DC power supply, supply batteries and inverters, and then by the inverter re-being turned into stable, pure, high-quality AC power. strong>AC power. It completely eliminates any power problems (voltage fluctuations, frequency fluctuations, harmonic distortions, and all kinds of interference) that may occur in the input power supply.
From the basic principle of application, UPS is a kind of power protection equipment containing energy storage device, with inverter as the main component, voltage and frequency stabilization output. Mainly by the rectifier, battery, inverter and static switch and other components.
UPS uninterruptible power supply role
1, voltage stabilization. A utility voltage is susceptible to power transmission line quality, for example, closer to the substation of the user voltage is higher about 130 ~ 120V, farther away from the substation of the user voltage is lower about 100 ~ 90V, such as voltage is too high or too low will make the user's equipment to shrink the life of the equipment, the seriousness of the equipment will be burned, the use of on-line UPS can provide a stable voltage power supply, the voltage varies less than 2V, which can extend the life of the equipment and the protection of the equipment. The on-line UPS can provide stable voltage power with voltage variation less than 2V, which can extend the equipment life and protect the equipment.
2, blackout protection. A utility power momentary terminal if equipped with UPS, then immediately by the UPS uninterruptible power supply will be converted to battery DC power AC power to continue to power the load.
3, high and low voltage protection. A utility voltage is too high or too low when the UPS built-in voltage regulator will make appropriate adjustments to keep the utility voltage in the usable range, if the voltage is too low or too high over the usable range, the UPS will be converted to AC battery DC power supply to continue to supply power to protect the user's equipment.
4, frequency stability. A utility frequency is divided into 50Hz/60Hz two kinds, the so-called frequency is the cycle of change every second, 50Hz is 50 cycles per second, Taiwan utility frequency is 60Hz, the mainland is 50Hz. generator operation by the client's sudden changes in electricity consumption caused by the changes in the speed of the power converted to power frequency fluctuation, the UPS UPS converted power can provide a stable The power converted by the UPS can provide a stable frequency.
