UPS is a kind of uninterruptible power supply containing energy storage device.
UPS is mainly used to provide uninterruptible power supply to some equipments which require high power stability.UPS is a kind of uninterruptible power supply containing energy storage device.
When the utility power input is normal, the UPS will be the utility voltage regulator supplied to the load, at this time, the UPS is an AC voltage regulator, while it is also charging the battery in the machine; when the utility power interruption (accidental blackout), the UPS will be immediately the battery's DC energy, through the inverter switching conversion method to the load to continue to supply 220V AC power to the load, so that the load maintains its normal work and protects the load software and hardware from damage. UPS equipment can usually provide protection against over-voltage or under-voltage.
UPS development characteristics
1, UPS using modular online parallel expansion function. At present, most of the high-power segment of the UPS have been equipped with redundant parallel function, UPS internal multi-module redundant parallel operation, and even more than one UPS system composed of redundant operation technology, in parallel operation, when a single module or single machine failure, its function is automatically transferred to the redundant unit to assume, and greatly improve the reliability of the UPS power supply system.
2, high efficiency, high reliability. Improve the energy efficiency of UPS itself, optimize the load efficiency curve, reduce the input current harmonics, and improve the power factor.
3, UPS digital, intelligent.
4, UPS green, energy saving, environmental protection. Energy saving and environmental protection has become the guiding principle of UPS product technology innovation. For UPS, the input power factor shows its ability to absorb grid active power and the degree of impact on the grid.
