There are two parts to measure the performance of UPS: one part is the adaptability to the utility grid and load; the other part is the technical performance of the UPS. These performances include: Input indicators:①Capacity②Input index 2 Input voltage, current and frequency range, phase number③Input power factor, input current harmonics)Output indicators:① Output voltage, output…
With the rapid development and wide application of computer industry, communication industry, various office equipment and precision electronic instruments, the demand for UPS is increasing, and the requirements are getting higher and higher. With the continuous improvement of manufacturing technology, the improvement of control technology and the continuous development of power devices, UPS has developed…
Take double-conversion online UPS as an example. According to the definition of UPS, UPS has two functions: one is that it can still provide uninterrupted power to the load when the mains fails; the other is to reduce voltage surges, high-voltage spikes, Transient over-voltage, voltage sag, line noise, frequency deviation, continuous low voltage and low-quality…
The so-called UPS power supply, that is, uninterruptible power supply, is a combination of lithium ups battery energy storage inside and a combination of rectifier and inverter as the main part. It is used to turn mains electricity into uninterrupted, high-quality communication required for stable computer operation. A kind of constant voltage and constant frequency…
Due to the complexity of the power supply and utilization of the mains power grid, such as the insufficient capacity of the mains power grid, the performance and quality problems of power transmission and transformation and various power distribution equipment, the irrationality of the configuration of various electrical equipment, and the inter-equipment Mutual influence, the…
