, namely, uninterruptible power supply, it is a kind of contain energy storage device, inverter as the main component of the constant pressure constant frequency of uninterrupted power supply.
Its main purpose is for a single computer, computer network system or other power electronic devices to provide uninterrupted power supply.
When normal mains input, UPS power supply will provide load mains voltage stability after using, UPS uninterruptible power supply at this time is pretty and an ac mains voltage regulator, at the same time it also to the internal battery recharged;
When mains interruption, UPS immediately to battery power, machine to load by the method of inverter transformation continues to supply 220 v alternating current (ac), make the load to maintain normal work and protect the software and hardware load from being damaged.
In addition, UPS power supply power for the protective equipment, its performance parameters is of great significance is one of our important consideration when the choose and buy.
Mains voltage input range wide, indicates to the use of mains ability (
Reduce the battery discharge)
Output voltage and frequency range is small, indicates to the mains adjustment ability is strong, stable output.
Waveform distortion rate is to measure the stability of the output voltage waveform, and voltage stability is that when UPS suddenly up from zero load to full load, the output voltage stability.
And UPS, power factor, conversion time efficiency are important parameters for characterization of UPS performance, determines the protection of the load capacity and utilization of grid.
Performance is better, to protect the stronger the ability, overall an off-line UPS protection for load, the worst of online interactive slightly, on-line can solve almost all of the common power problems.
The increasing consumption demand in key segments such as stabiliser for ac, three phase voltage regulator
and stabiliser for ac have been driving the sales of and its derivatives worldwide.
